    For anyone else out there who's struggling with DDR3 SDRAM on the Arty A7, here's a project for Vivado 2019.2 that builds out-of-box and successfully reads / writes (via the MIG user interface) to / from memory. Hopefully this'll save someone the pain I went through figuring out how to interface with the DDR-SDRAM via Verilog. Arty-SDRAM.zip

    Hi everyone, LINX can be installed on the Raspberry Pi 4. The LINX 3.0 Target Manual Install Process (https://www.labviewmakerhub.com/doku.php?id=learn:libraries:linx:misc:target-manual-install) did not work due to changes in the latest version of Raspbian. Here is the procedure that I used to install LINX. The procedure also works on the Raspberry Pi 2B, Pi 3A+, Pi 3B and Pi 3B+ running Raspbian Buster. 1. Setup the Raspberry Pi using the latest Raspbian Buster Image. 2. Change the default password for the Pi account on the Raspberry Pi. 3. Setup a WiFi or Ethernet connection from the Raspberry Pi to your router. 4. Enable SSH on the Raspberry Pi. 5. SSH into the Raspberry Pi or open a terminal window on the Raspberry Pi desktop. 6. Check that the Raspberry Pi can access the Internet by entering the command ping -c 4 raspberrypi.org 7. Enter the commands shown in bold below. Note: The text may wrap due to the web browser window size. I recommend copying the text into a text editor to see the original formatting. The commands are in the attached file linx_install_commands.txt # Enable i2c and spi sudo raspi-config nonint do_i2c 0 sudo raspi-config nonint do_spi 0 # Update Raspbian sudo apt-get update sudo apt-get dist-upgrade -y # Install LINX sudo sh -c 'echo "deb [trusted=yes] http://feeds.labviewmakerhub.com/debian/ binary/" >> /etc/apt/sources.list' sudo apt-get update sudo apt-get install -y lvrt-schroot # Move the nisysserver.service and labview.service files to the systemctl folder sudo mv /etc/systemd/system/multi-user.target.wants/nisysserver.service /lib/systemd/system sudo mv /etc/systemd/system/multi-user.target.wants/labview.service /lib/systemd/system # link liblinxdevice.so to the Raspberry PI device driver file liblinxdevice_rpi2.so sudo schroot -c labview -d /usr/lib -- ln -s liblinxdevice_rpi2.so liblinxdevice.so # Enable the nisysserver.service and labview.service to start on boot sudo systemctl enable nisysserver.service sudo systemctl enable labview.service # Start the nisysserver.service and labview.service sudo systemctl start nisysserver.service sudo systemctl start labview.service You should now be able to connect to the Raspberry Pi from the LabVIEW Project Explorer.

    MTDS PMOD Connection issue

    Hello @WillTx, 1. There is an IP for Pmod MTDS with the drivers you need to make your Pmod MTDS working. It also contains 10 demos from which you can learn a lot. You can find it here : https://github.com/Digilent/vivado-library/tree/master/ip/Pmods/PmodMTDS_v1_0. You need to download the entire vivado-library (from here) then follow the tutorial for using Pmod IP cores in Vivado. 2. Your block design after adding the Pmod MTDS IP: 3. You can use the board flow to automatically connect to JB Pmod connector without a XDC constrain file (as it shows in the tutorial at step 3). You need to install the board files first. If you want to use the Cora-Z7-07S-Master.xdc constraint file, below are the lines corresponding to JB Pmod connector : 4. Please follow the REAME.txt found in drivers/PmodMTDS_v1_0/examples/ Cheers, Ana-Maria

    FTDI chip not recognized anymore

    I think it's Linux... Try the "dmesg" command immediately after plugging or unplugging. It should show some related events. The obvious, try with a different computer and a different cable. Especially cables fail often.

    Hi, reading between the lines of your post, you're just "stepping up" one level in FPGA design. I don't do long answers but here's my pick on the "important stuff" - Before, take one step back from the timing report and fix asynchronous inputs and outputs (e.g. LEDs and switches). Throw in a bunch of extra registers, or even "false-path" them. The problem (assuming this "beginner mistake") is that the design tries to sample them at the high clock rate. Which creates a near-impossible problem. Don't move further before this is understood, fixed and verified. - speaking of "verified": Read the detailed timing analysis and understand it. It'll take a few working hours to make sense of it but this is where a large part of "serious" design work happens. - Once the obvious problems are fixed, I need to understand what is the so-called "critical path" in the design and improve it. For a feedforward-style design (no feedback loops) this can be systematically done by inserting delay registers. The output is generated e.g. one clock cycle later but the design is able to run at a higher clock so overall performance improves. - Don't worry about floorplanning yet (if ever) - this comes in when the "automatic" intelligence of the tools fails. But, they are very good. - Do not optimize on a P&R result that fails timing catastrophically (as in your example - there are almost 2000 paths that fail). It can lead into a "rabbit's hole" where you optimize non-critical paths (which is usually a bad idea for long-term maintenance) - You may adjust your coding style based on the observations, e.g. throw in extra registers where they will "probably" make sense (even if those paths don't show up in the timing analysis, the extra registers allow the tools to essentially disregard them in optimization to focus on what is important) - There are a few tricks like forcing redundant registers to remain separate. Example, I have a dozen identical blocks that run on a common, fast 32-bit system clock and are critical to timing. Step 1, I sample the clock into a 32-bit register at each block's input to relax timing, and step 2) I declare these register as DONT_TOUCH because the tools would otherwise notice they are logically equivalent and try to use one shared instance. This as an example. - For BRAMs and DSP blocks, check the documentation where extra registers are needed (that get absorbed into the BRAM or DSP using a dedicated hardware register). This is the only way to reach the device's specified memory or DSP performance. - Read the warnings. Many relate to timing, e.g. when the design forces a BRAM or DSP to bypass a hardware register. - Finally, 260 MHz on Artix is already much harder than 130 MHz (very generally speaking). Usually feasible but you need to pay attention to what you're doing and design for it (e.g. a Microblaze with the wrong settings will most likely not make it through timing). - You might also have a look at the options ("strategy") but don't expect any miracles on a bad design. Ooops, this almost qualifies as "long" answer ...

    Hi @Kris Persyn, It depends on how you manage your resources, driving immersive visuals on a HDMI display can be done in multiple ways at different resolutions, some are PL taxing others are DDR taxing; you could generate entire frame buffers in PL or PS or you could find a optimal algorithm to change just the previous frame or you could allocate a high number of frame buffers and then run them in a loop. It also depends on how math lab synthesizes the IP you will need to add to your design. If you design your project properly and don't aim for a resolution higher more 720p( I'm being conservative, we managed to drive the HDMI at 1080p with processing filters without a problem) I think it should be enough for what you want to do, resource wise. My suggestion, download and install Vivado, download and install the board files, create and implement your project look at the resource consumption and then buy a board. - Ciprian

    In your constraint file, the ddc pins have lowercase "ddc_scl_io" and "ddc_sda_io". Your block design has the port in uppercase "DDC". The case must match. Try editing your constraint file to have "DDC_scl_io" and "DDC_sda_io".

    Access to the GPIO with the API

    I'm not competent to lecture on software best practices but this topic merits discussion. Perhaps a few comments will kick one off and lure people better qualified than me to participate. There are ways of accessing hardware from software applications in just about anyway you choose. That doesn't mean that hey are all ideal or even acceptable. As a rule, using well worn libraries are preferred. In general they are not the fastest or the easiest or most simple way to interact with hardware. For safety, consistency, and orderliness they are better than reference by address. One concept is hard to argue against. If there is a possibility that another application or process has access to the same hardware then direct manipulation of hardware is a very dangerous thing to do. For some embedded projects you are guaranteed that only your code is running. This doesn't mean that direct access is a wise choice, especially if you have levels of interrupts running. For embedded systems that have an OS or RTOS where hardware is specifically isolated from end user applications by design, direct access of hardware is rather foolish because you have no control over what code the processor(s) is running a any given instant. Worse yet direct manipulation of hardware creates a situation in which neither you nor your OS can know what the state of your hardware is at any given moment. You can always alter your OS by adding kernel mode drivers if the standard ones don't fit your needs. The bottom line is understand the consequences for your design choices and code safely. You are guaranteed to pay for bad choices. For software development a general rule of thumb is that if what you are doing is direct and simple then it's likely a bad idea.

    It's been too long ago but I do remember taking the scenic side journey into investigating performance of floating point on Intel processors. Mostly what I remember is that it was interesting, informing, had unexpected surprises and was a valuable exercise. Just recommending the excursion to anyone interested in 'bit exactness'.

    I've spent some time since my first post trying to figure out what's in store for users with Vitis. With Vivado 2019.2 + Vitis you still need a Linux host to develop Petalinux applications. It was a chore, but I did manage to install Petalinux 2019.1 onto a Ubuntu 18.04 VM running in HyperV on my Win10 Pro box. This PC has 32 GB ram so I can allocate 8 GB to the VM. I haven't as yet actually created a project with the Petalinux tool this way yet. My plan is to wait and see how well Xilinx develops the tools with the next release before moving to 2019.2 and the new paradigm. Note that Vivado 2019.2 also breaks even Xilinx IP created in previous versions. For now I'm sticking with VIvado 2019.1 and Petalinux 2019.1. In 2019.2 tools Vivado and Vitis are not integrated. You still have to export hardware but you can't launch Vitis from Vivado. I'm assuming that at some point in the future users will start off in Vitis and launch Vivado from within that IDE. ** It's been my experience that overall performance with Linux VMs in WIn10 is poor unless you start with one of the 'optimized' quick start images from Msoft. Unfortunately, there is no way to change the default disk size of 12 GB, which is way too small do doing anything useful... like even install Petalinux. You can resize the VM disk size after creating the VM but you still need to install a disk management tool like Gparted onto your VM to re-size the Unbuntu partition to make use of the expanded disk size. Needless to say all of this should be done before completely setting up and updating the VM. The whole process of installing Petalinux was rather messy and time consuming. And HyperV is... well Msoft, so get used to frustration, pain and misery.

    Hi @attila Thank you again for all the support you've provided me for the past weeks. I am now capable of receiving more than 409 characters using the Wrapper I created base from your example. It uses the Record acquisition mode and I set the buffer size to 3 million for now. I'll increase it when the need arises. I used 1 UART controller and branched out its Tx pin to 2 DIO pins of the AD2 (DIO #0 & 1). I transmitted 500 characters: (If Record mode is not the acquisition mode, the received result will be blank) For DIO # 0, it received: with a length of: For DIO #1, it received: with a length of: I could not have done it without your guidance, thank you again and more power to you and Digilent Best regards, Lesiastas

    I own three of FMC equipped boards that you mention and frequently use at least one on a regular basis. Just for arguments sake; lets say that I want to design my own FMC mezzanine card using all of those differential pairs. Where do I find the trace routing report letting me know what the trace lengths are for the Genesys2, Nexys Video and Zedboard?

    Yes, that cable is suitable from connection perspective. Still, there are functionality issues that you must be concerned. Most of the Pmods communicate using protocols like SPI, I2C, etc. This is specified on the Pmod datasheet. This means that the pins corresponding on the maching connector (on the system board) must implement that specific functionality. Normally using a FPGA board will be easier to configure Pmod pins to the needed functionality. Still, as you use a microcontroller board, this might be more difficult or even impossible. Please check if the pins associated to the Pmod rows correspond with the associated function on the Pmod. Another possibility is to re-configure the pins if your microcontroller allows pins reconfiguration. Please check (in the board schematic) which microcontroller pins are connected to the Pmod connector, and then check (in the microcontroller datasheet) the functions for these pins. Good luck.

    Hi, Sorry to barge in, but if anybody can point me to the Hibbert Transformer info I would be very grateful. However, here is an FPGA friendly way to calculate mag = sqrt(x*x+y*y), with about a 99% accuracy. You can easily see the pattern to get whatever accuracy you need. #include <math.h> #include <stdio.h> #define M_SCALE (16) /* Scaling for the magnitude calc */ void cordic_mag(int x,int y, int *mag) { int tx, ty; x *= M_SCALE; y *= M_SCALE; /* This step makes the CORDIC gain about 2 */ if(y < 0) { x = -(x+x/4-x/32-x/256); y = -(y+y/4-y/32-y/256); } else { x = (x+x/4-x/32-x/256); y = (y+y/4-y/32-y/256); } tx = x; ty = y; if(x > 0) { x += -ty/1; y += tx/1;} else { x += ty/1; y += -tx/1;} tx = x; ty = y; if(x > 0) { x += -ty/2; y += tx/2;} else { x += ty/2; y += -tx/2;} tx = x; ty = y; if(x > 0) { x += -ty/4; y += tx/4;} else { x += ty/4; y += -tx/4;} tx = x; ty = y; if(x > 0) { x += -ty/8; y += tx/8;} else { x += ty/8; y += -tx/8;} tx = x; ty = y; if(x > 0) { x += -ty/16; y += tx/16;} else { x += ty/16; y += -tx/16;} *mag = ty/M_SCALE/2; /* the 2 is to remove the CORDIC gain */ } int main(int argc, char *argv[]) { int i; int cases = 300; printf("Irput Calculated CORDIC Error\n"); for(i = 0; i < cases; i++) { float angle = 2*M_PI*i/cases; int x = sin(angle)*20000; int y = cos(angle)*20000; int mag, a_mag = (int)sqrt(x*x+y*y); cordic_mag(x,y, &mag); printf("%6i %6i = %6i vs %6i %4i\n", x, y, a_mag, mag, mag-a_mag); } } Oh, here is the output with a couple more iterations added.

    Hey guys, I've made some experiments that could be interesting for your as well. I put tap water into my ceramic container, I heated it to different temperatures and measured the impedance every 5 degrees. You can see the values between 60 ° Celsius (140 ° Fahrenheit) and 5 ° Celsius (41 ° Fahrenheit). Red is 60 Celsius, blue is 5 Celsius and there are 10 steps between them.

    Analog Discovery 2 vs Raspberry Pi 3

    Szia and Attila I got a Raspberry Pi 4 last week on release day (got the 2GB version as they sold out of 4GB in half a day) . Just got it plugged into the Analog Discovery and it works! Not really tried it for long but it seems to work reliably, but only well on USB3. On USB3 port, first time it wasn't recognised, but tried again after swapping devices around a then it was detected. Maybe it clashed with my wireless mouse dongle When I tried USB2 port, it connected immediately but I found that every few minutes (max 5-10mins) it would throw a device error window and I would have to clear and reconnect. Maybe RPi foundation kept the FTDI chipset for USB2 and used a new one for USB3 (Pi datasheet only says there is one chipset and it's not FTDI). I will try and soak test tomorrow, but looking good on USB3. So far it has been running 23mins with no apparent glitches, and Chromium tabs open. Waveforms taking 13-20% of CPU in task manager.

    Thinking of which... actually I do have a plain-Verilog FIFO around from an old design. It's not a showroom piece but I think it did work as expected (whatever that is...) For 131072 elements you'd set ADDRBITS to 17 and DATABITS to 18 for 18 bit width. module FIFO(i_clk, i_reset, i_push, i_pushData, i_pop, o_popAck, o_popData, o_empty, o_full, o_error, o_nItems, o_nFree); parameter DATABITS = -1; parameter ADDRBITS = -1; localparam ADDR_ZERO = {{(ADDRBITS){1'b0}}}; localparam ADDR_ONE = {{(ADDRBITS-1){1'b0}}, 1'b1}; localparam DATA_X = {{(DATABITS){1'bx}}}; input wire i_clk; input wire i_push; input wire i_reset; input wire [DATABITS-1:0] i_pushData; input wire i_pop; output reg o_popAck = 1'b0; output wire [DATABITS-1:0] o_popData; output reg o_error = 1'b0; output wire [31:0] o_nItems; output wire [31:0] o_nFree; output wire o_empty; output wire o_full; reg popAckB = 1'b0; reg [DATABITS-1:0] mem[((1 << ADDRBITS)-1):0]; reg [ADDRBITS-1:0] pushPtr = ADDR_ZERO; reg [ADDRBITS-1:0] popPtr = ADDR_ZERO; reg [DATABITS-1:0] readReg = DATA_X; reg [DATABITS-1:0] readRegB = DATA_X; wire [ADDRBITS-1:0] nextPushPtr = i_push ? pushPtr + ADDR_ONE : pushPtr; wire [ADDRBITS-1:0] nextPopPtr = i_pop ? popPtr + ADDR_ONE : popPtr; assign o_popData = o_popAck ? readReg : DATA_X; // === items counter === // note: needs extra bit (e.g. 4 slots may hold [0, 1, 2, 3, 4] elements) reg [ADDRBITS:0] nItems; assign o_nItems = {{{31-ADDRBITS-1}{1'b0}}, nItems}; assign o_nFree = (1 << ADDRBITS) - nItems; localparam NITEMS_ONE = {{(ADDRBITS){1'b0}}, 1'b1}; assign o_empty = nItems == 0; assign o_full = nItems == {1'b1, {{ADDRBITS}{1'b0}}}; always @(posedge i_clk) begin // === preliminary assignments === readRegB <= DATA_X; popAckB <= 1'b0; case ({i_push, i_pop}) 2'b10: nItems <= nItems + NITEMS_ONE; 2'b01: nItems <= nItems - NITEMS_ONE; default: begin end endcase o_error <= (i_push && ~i_pop && o_full) || (i_pop && o_empty); // === output register (delay 1) === o_popAck <= popAckB; readReg <= readRegB; pushPtr <= nextPushPtr; popPtr <= nextPopPtr; if (i_push) mem[pushPtr] <= i_pushData; if (i_pop) begin readRegB <= mem[popPtr]; popAckB <= 1'b1; end if (i_reset) begin pushPtr <= ADDR_ZERO; popPtr <= ADDR_ZERO; o_error <= 1'b0; o_popAck <= 1'b0; popAckB <= 1'b0; readReg <= DATA_X; readRegB <= DATA_X; nItems <= 0; end end endmodule

    Read from MicroSD in HDL, Write on PC

    Hi @dcc, I'm not certain how you are verifying that the HDL is writing to and then reading back from the SD card in a normal formatting style, but in general FAT32 is a widely used format for SD cards that has existing material for it. I am uncertain why you are using a special tool to write to the SD card though; from what I can tell the tool is Windows compatible, so why not just use the Notepad program which comes with Windows and save a .txt file with the data you are interested in reading to the SD card or just using Windows Explorer (the file manager) to move the file of interest onto the SD card? If you do have a header in your file, you will need to take account for that, though I do not know what you mean by "random file" in this case. Thanks, JColvin

    Hi JColvin, I am definitely not using ISE. I think JPeyron had it correctly. I didn't have my board.Repopaths variable set and so the project wasn't finding the board files. Once I set this variable as suggested, the pin mapping and IO types were auto populated as expected. Kudos, Sean

    OpenCV and Pcam5-c

    Hi @Esti.A, SDx, which includes SDSoC (Software Defined System on Chip), is a development environment that allows you to develop a computer vision application, in your case, using C/C++ and OpenCV library. The target of SDx-built applications are Xilinx systems on chip (SoC) (Zynq-7000 or Zynq Ultrascale+). Xilinx SoC architecture has two main components: ARM processor (single or multi core) named Processing System (PS) and FPGA, named Programmable Logic (PL). Using SDx to build an application for SoC allows you to choose which functions from your algorithm are executed in PS and which ones are executed in PL. SDx will generate all data movers and dependencies that you need to move data between PS, DDR memory and PL. The PL is suitable for operations that can be easily executed in parallel. So if you are going to choose a median filter function to be executed in PL, instead of PS, you will obtain a better throughput from your system. As you said, you can use OpenCV to develop your application. You have to take into account that OpenCV library was developed with CPU architecture in mind. So the library was designed to obtain the best performance on some specific CPU architectures (x86-64, ARM, etc.). If you are trying to accelerate an OpenCV function in PL using SDx you will obtain a poor performance. To overcome this issue, Xilinx has developed xfopencv, which is a subset if OpenCV library functions. The functionalities of xfopecv functions and OpenCV functions are the same but the xfopencv functions are implemented having FPGA architecture in mind. xfopencv was developed in C/C++ following some coding guideline. When you are building a project, the C/C++ code is given as input to Xilinx HLS (High Level Synthesis) tool that will convert it to HDL (Hardware Description Language) that will be synthetized for FPGA. The above mentioned coding guideline provides information about how to write C/C++ code that will be implemented efficiently in FPGA. To have a better understanding on xfopencv consult this documentation. So SDx helps you to obtain a better performance by offloading PS and by taking advantage of parallel execution capabilities of PL. Have a look on SDSoC documentation. For more details check this. An SoC is a complex system composed by a Zynq (ARM + FPGA), DDR memory and many types of peripherals. Above those, one can run a Linux distribution (usually Petalinux, from Xilinx) and above the Linux distribution, the user application will run. The user application may access the DDR memory and different types of peripherals (PCam in your case). Also, it may accelerate some functions in FPGA to obtain a better performance. To simplify the development pipeline Xilinx provides an abstract way to interact with, named SDSoC platform. SDSoC platform has two components: Software Component and Hardware Component that describes the system from the hardware to the operating system. Your application will interact with this platform. You are not supposed to know all details about this platform. This was the idea, to abstract things. Usually, the SDSoC platforms are provided by the SoC development boards providers, like Digilent. All you have to do is to download the last SDSoC platform release from github. You have to use SDx 2017.4. You don't have to build your own SDSoC platform. This is a complex task. You can follow these steps in order to build your first project that will use PCam and Zybo Z7 board. The interaction between PCam and the user application is done in the following way: there is an IP in FPGA that acquires live video stream from the camera, the video stream is written into DDR memory. This pipeline is abstracted by the SDSoC platform. The user application can access the video frames by Video4Linux (V4L2). The Live I/O for PCam demo shows you how to do this. I suggest you to read the proposed documentation to obtain a basic knowledge needed for SDSoC projects development. Best regards, Bogdan D.

    Hi, there's a lot of new information in your last post. You aren't just "trying" FPGA but have a professional interest in Zynq. Don't let anybody scare you it's "difficult" and go for it, possibly with the cheapest board, no tutorials and low expectations like, blinking LEDs for quite a while. Given the price tag of any industrial training coarse, an FPGA board for self-study is a no-brainer. Maybe save some money to buy your FPGA engineer a coffee once a week, with some questions in mind

    Pmod DA3 clocking

    It looks to me like DA3_WriteSpi() was adapted from code for a different device and has vestigial and incorrect code. Reviewing the AD5541A datasheet, several things stand out There is only a single register in the chip so there is no need for the u8 reg parameter. There is no need for a"config byte" to be sent before the data. The transfer is always 16 bits so there is no need to allow for arbitrary length data quoting from the datasheet "Input data is framed by the chip select input, CS. After a high-to-low transition on CS, data is shifted synchronously and latched into the serial input register on the rising edge of the serial clock, SCLK. After 16 data bits have been loaded into the serial input register, a low-to-high transition on CS transfers the contents of the shift register to the DAC register if LDAC is held low". Reviewing the PmodDA3 schematic, the ~LDAC signal is softly pulled to ground with a 10K resistor. So there is no need to explicitly toggle ~LDAC. What all this means is DA3_WriteSpi could be simplified to something like void DA3_WriteSpi(PmodDA3 *InstancePtr, u16 wData) { u8 bytearray[2]; bytearray[0] = ((wData & 0xFF00) >> 8); bytearray[1] = (wData & 0xFF); XSpi_Transfer(&InstancePtr->DA3Spi, bytearray, 0, sizeof(bytearray)); } You would then call it passing in just the instance pointer and the value you want to write to the DAC. u16 dacValue = 1234; DA3_WriteSpi(&myDevice, dacValue); I do not have a PmodDA3 on my bench so I cannot verify the function works, You can give it a try and let us know how it goes.

    Pmod DA3 clocking

    It seems to me the AXI Quad SPI block is sending address + data. Looking at the .xci file again, I see C_SPI_MEM_ADDR_BITS set to 24 bits. So 24 bits of address and 16 bits of data would yield 40 bits.

    Pmod DA3 Pinout

    That is one of the conventions commonly used to indicate an Active Low signal. So in this case, you pull Chip Select low when you want to access the chip. After you have toggled in all the data bits on the DIN line, you pull LDAC low. The Pmod DA3 reference manual has a link to the D/A chip's datasheet. That is the best first place to look for information on the device's function. The required signal timings are on page 5 of the datasheet.

    Hi @neocsc, Here is a verified Nexys Video HDMI project updated from Vivado 2016.4 to Vivado 2017.4. You should be able to find the updated project in the proj folder . Here is a GitHub project done in HDL using the clocking wizard, DVI2RGB and RGB2DVI IP Cores for another FPGA. Here is a unverified Nexys Video Vivado 2017.4 HDMI pass through project made from the linked Github project. In the next few days I should have the bandwidth to verify this project. thank you, Jon

    The hot plug detect should be on the rx side. The source will see that and will then initiate the DDC conversation.

    Hi @neocsc, Please attach a screen shot of the error. Not all timing errors will break a project. 1) Are you still able to generate a bitstream or does the timing error force the bitstream generation to stop? 2) If you are able to generate a bitstream please export the hardware(include bitstream), launch sdk and import application. Then program the fpga and run as ->launch on hardware(system debugger). 3) If so does the project make a serial terminal menu? $) If so does the project generate a HDMI pass through along with a pre-generated image? thank you, Jon

    The answer is yes, that fixed it! Thank you so much! The odd thing is that I tried this in one of my attempts and put it back to QSPI as it didnt work. Regardless thank you so very much for walking me through this. all looks good now:

    So the picture that you post of a (relatively) gigantic scope probe clip resting on a fairly small FPGA device in a BGA package is a way of making a statement. It might also be viewed as a picture that might be making a statement to you. I routinely use an LED to verify that my design is at least being clocked properly. Make a 32-bit counter and connect bit 26 or so to an obuf driving one of the boards LEDs. You can get an approximation of a 1 blink/s LED rate with a little math depending on the clock rate and the chosen counter bit. For me the clock rate of interest isn't the external clock coming into the FPGA but some clock output of an MMCM or PLL that I'm using for my design. If the LED is blinking then I at least know that something is alive in my design. You've got to be careful with those large scope probe grabbers around fine pitch components. I prefer to bring out a few debug versions of particular signals of interest to a PMOD and connect that to a scope probe ( the PMOD has DGND pin(s) ). You still have to exercise some caution with the ground clip on your scope probe as it's easy to short an adjacent pin to ground and ruin your day. It would be very useful if Digilent provided GND test points, or at least holes for test points, in an area of their boards for scope probing. The safest thing might be to stick a pin into the GND receptacle of one PMOD connector and probe on signals in another. Insulation stripped off suitably sized wires can help as well to keep ground clips from accidents. It's really easy to have that ground clip pop off whatever it's connect to and bounce around on exposed parts of your board; nothing good will come of that. I limit scope probing to when it's necessary. There are usually safer ways to evaluate signals in your FPGA design. Lastly, you should understand that its very easy to get a false impression of what a signal looks like, especially with normal scope probe ground clips. Think Heisenberg.

    Cmod S6 - Multilayer?

    You might go to Texas Instruments' site (or AD or both) and find documentation for some $500 high frequency ADC or DAC eval board as example to study.. There's nothing wrong with copper planes, generally. Free-standing structures (such as non-connected filler polygons) can be bad, if they resonate. So are loops if the driving wire spans an area together with the GND return wire (for which the ground plane is an obvious solution). The worst resonators have high quality factor meaning loose coupling meaning it can be surprising how the energy managed to couple in. There's no such thing as too many ground vias... Note, your ground plane can do very interesting things in combination with the metal box it's in (resonant cavity) but that's a different story.

    And.... I have this sense that if you keep describing what you did you will answer your own question. I don't have enough information yet to help. [I confess that I haven't bothered to read through your code] Verbalizing problems, if you go into enough detail, is often a fairly reliably way to resolve them. Sometimes it helps to have someone throw in a good question or two.

    You are not wrong - but for that device ID the tooling will not let you use all the LUTs present on the silicon die. It is a somewhat artificial restriction, and might have some implications for the power and thermal properties of the package (e.g. a smaller package may not be able to dissipate the heat).

    Hi, Abdul, Here are my notes/recommendations: 1. Open your block diagram in Vivado where you created BRAM configuration and then check the address editor. You should see whether the BRAM address was assigned. If you find assigned see axi_bram_ctrl_0 OffsetAdress and the Range then the BRAM was created and mapped to the memory. 2. Writing and reading from BRAM requires a clock signal. Check Xilinx templates for BRAM which you can access inside the Vivado. I am not sure that the code you've used to write into BRAM does anything. 3. You don't use an absolute address in your HDL when BRAM created in Vivado. Vivado maps the address 0x4000_0000 to 0. So you can start from the address 0 and it will be the lowest address of the BRAM. If your don't use Vivado then you will need to define your block in HDL and include addresses, and many other parameters. 4. The C-code in SDK should use BRAM address from the file parameters.h. You just need to use XPAR_AXI_BRAM_CTRL_0_S_AXI_BASEADDR as the begining of the BRAM address space. 5. You can treat BRAM as RAM meaning that all read/write operators are the same. For example you can copy BRAM content into the RAM: for(i = 0 ; i < BRAM_SIZE ; i++) *(destination + i) = *(source + i); where source = XPAR_AXI_BRAM_CTRL_0_S_AXI_BASEADDR Disclaimer: always read documentation, whatever you find on Internet might not be correct. Good luck!

    Hi @akhilahmed, In the mentioned video tutorial, the leds are controlled using "xgpio.h" library but the application is standalone. If you want to use a linux based application you have to use linux drivers for controlling. In the current Petalinux build, which is used in SDSoC platform, UIO driver is the best approach. Steps: 1. Vivado project generation: - Extract .dsa archive from /path_to_sdsoc_platform/zybo_z7_20/hw/zybo_z7_20.dsa - Launch Vivado - In Tcl Console: cd /path_to_extracted_dsa/prj - In Tcl Console: source rebuild.tcl - In this point you should have the vivado project which is the hardware component of SDSoC platform. Open Block Design. Change to Address Editor Tab. Here you will find the address for axi_gpio_led IP: 0x4122_0000 2. Petalinux UIO driver: - Launch SDx - Import zybo-z7-20 SDSoC platform - Create a new SDx linux based project using a sample application (e.g. array_zero_copy) - Build the project - Copy the files from /Dubug/sd_card to SD card - Plug the SD card in Zybo Z7. Make sure that the JP5 is set in SD position. Turn on the baord - Use your favorite serial terminal to interact with the board (115200, 8 data bits, 2 stop bits, none parity) - cd to /sys/class/uio - if you run ls you will get something like: uio0 uio1 uio2 uio3 uio4 uio5 - Now you have to iterate through all these directories and to search for the above mentioned axi_gpio_led address: 0x4122_0000 - For example: cat uio0/maps/map0/addr will output: 0x41220000, which means that the axi_gpio_led can be accessed using linux uio driver through uio0 device. - Code: #include <stdio.h> #include <stdlib.h> #include <sys/ioctl.h> #include <sys/mman.h> #include <stdint.h> #include <unistd.h> #include <fcntl.h> #define UIO_MEM_SIZE 65536 #define UIO_LED_PATH "/dev/uio0" void UioWrite32(uint8_t *uioMem, unsigned int offset, uint32_t data) { *((uint32_t*) (uioMem+offset)) = data; } uint32_t UioRead32(uint8_t *uioMem, unsigned int offset) { return *((uint32_t*) (uioMem+offset)); } void led_count_down(uint8_t *ledMem) { uint8_t count = 0xF; uint8_t index = 0; for (index = 0; index < 5; index++) { UioWrite32(ledMem, 0, count); count = count >> 1; sleep(1); } } int main() { // Set Leds as output int led_fd = open(UIO_LED_PATH, O_RDWR); uint8_t *ledMem = (uint8_t *) mmap( 0, UIO_MEM_SIZE, PROT_READ | PROT_WRITE, MAP_SHARED, led_fd, (off_t)0); UioWrite32(ledMem, 4, 0x0); // Set all leds as output while(1) { // Start led count-down led_count_down(ledMem); } return 0; } - Build the project and copy the content of Debug/sd_card on SD sd_card - Power on the board and connect to it using a serial terminal - run the following commands: mount mmcblk0p1 /mnt cd /mnt ./project_name.elf - Result: A countdown should be displayed on leds.

    AD2 over voltage :-(

    Hi @peter taylor This was a ferrite between the Analog Discovery and USB ground. Supposed to filter noise from USB cable/PC which acted as a fuse... You can solder a simple short instead this ferrite. Hopefully only this was damaged. Be careful. The devices and circuits should have the same ground. The AD ground is connected to the PC ground over the USB cable.

    Zynq book - tutorial 5 Zybo Z7

    Hi @n3wbie, Th working project is attached. what you have to take in to account when using this audio codecs with Digilent products is that you need to configure the codec (using I2C) as well as receive the samples using I2S IP core. Basically one is for the control of the codec and the other one is to receive the samples. I have written a small driver for both the I2S core and the I2C SSM2603 which is in the source files of the SDK project (in the sdk folder) which configures the registers for the codec and I2S IP core; the documentation for the codec can be found here. The IP core has not yet been documented which is the main reason we have not added it to the Digilent vivado-ip library, but it needs a 100MHz input for it to be able to synthesize the 12.228 MHz MCLK and the subsequent clocks for the I2S protocol. The demo project reads the buttons and based on the ones you press it will: BTN0 - Record 1s BTN1 - Set Mic input BTN2 - Set Line In input BTN3 - Playback 1s The project is not really optimized so it uses a variable "RecSamples", allocated to the stack memory which holds the recorded samples(48000 samples representing 1s at a 48KHz sampling rate) and it is also used fro play back, so don't press play back before record. The rest should be easily traceable from the comments in the driver and the main source code. If you have any other questions feel fr to ask. Ciprian ZyboZ7Audio.zip

    Arty A7 flash chip

    Hi @[email protected], I believe the new part that is used in the Arty A7 boards (and other A7 boards) is now a Spansion S25FL128SAGMF100; based on old schematics, I believe this was added in Rev D of the Arty A7 (dated August 2017), though I do not know when that particular Rev was then released (or if it even was released) to the public. I confirmed that the Arty S7 also uses this part and I wouldn't be surprised if most of our other Artix 7 based boards use it now as well. I've requested that the chip name and images are updated in any appropriate tutorials and requested that the pdf version of the reference manual (updated wiki) is updated as well. Thanks, JColvin

    MMCM dynamic clocking

    Hey, something else I just saw when reading the clocking guide was: MMCM Counter Cascading The CLKOUT6 divider (counter) can be cascaded with the CLKOUT4 divider. This provides a capability to have an output divider that is larger than 128. CLKOUT6 feeds the input of the CLKOUT4 divider. There is a static phase offset between the output of the cascaded divider and all other output dividers. And: CLKOUT4_CASCADE : Cascades the output divider (counter) CLKOUT6 into the input of the CLKOUT4 divider for an output clock divider that is greater than 128, effectively providing a total divide value of 16,384. So that can divide a 600 MHz VCO down to 36.6 kHz.
