  1. Hello, I am Raghu, doing my Master Thesis. I am using Zedboard to emulate few sensor's signals. I have already implemented DA1 and AD2 on to Zedboard and connected in the loop. They both work perfectly fine. But next step was to implement DA4 in my design, and I didn't find any drivers for the same. So I tried using normal AXI SPI IP in the hardware design for DA4 and tried to develop my own driver (considering DA1's driver as an example). All the initialization part works perfectly fine and the communication also takes place as per DA4's datasheet. But when it is asked to send data, it is not sending the exact data. Any help regarding the same would be very helpful. Please find the attached for my complete SDK project and a separate Program file. DA_4.zip DA_4_Prog.zip
  2. Hi, I want to read analog data from ad1 pmod. For Vivado part, I use digilent pmod ips to connet fpga. For SDK part, I use AD1.h and AD1.c library in examples. My sensor sends to me analog values between 0-3.3V. (This is a heart rate ECG values). During using arduino, all heart beat data can be read. But I use same function for zedboard, Analog values doesnt look like arduino's. How I can configure and fix this problem? As you see ad1-zedboard connection as below.
  3. Hello, I want to access analogue pin of XADC header to input audio data in FPGA (Virtex VC707 here). But i am getting error in writing bit-stream "Partially routed nets". Design is below: As we provide the pin number and voltage standard in constraint file for pin assignment, but here the I/O Std is faded and cannot be edited. I have also edited constraint file manually but still getting this error. Pin assignment are as under for VC707 Schematics diagram for VC707 Any help will be appreciated. Thanks,
  4. Hello, I have recently purchased Zedboard along with Pmods AD1 and DA4. I want to implement Gradient Descent algorithm in the Zedboard using these Pmods with bandwidth more than 100 kHz. To get started, I tried to regenerate a analog signal using the Pmods AD1 and DA4. The experiment is completely explained with block design and output plots in the ADC_DAC_1_compressed.pdf. The SDK C code for acquistion and generation (adc_dac.c) as well as for finding max. working speed of DAC (dac_maxv.c) are atttached. The ADC clk is set to 20 MHz and DAC clk is to 50 MHz. It could be observed from the ADC_DAC_1_compressed.pdf that the maximum speed (frequency) the DAC (DA4) can write is only 33 kHz. The desirable acquisition and generation rate should be more than 200 kHz for my case. I identified that, the Xspi transfer written in the code (adc_dac.c) sends only 8 bits out of 32 bits of the DAC per clock cycle. Can we directly write all the 32 bits of the DAC in a single clk cycle using SDK ?? or is there any other way to make the ADC and DAC work faster?? What am I missing?? Looking forward to you suggestions and other similar references. Thanks in advance
  5. Hi, I have a ZEDBOARD which I want to interface it to an analog input signal and see the sinusoidal output. i'm following lab 3 tutorial by Adam Taylor. So, as for the first step, I tried to connect the signal generator to Vn and Vp. I expected to see the sinusoidal shape of the voltage in XADC dashboard (XADC wizard demo). and also set the ENABLE_ALL_AUXILIARY_CHANNELS check mark, which will include Vp/Vn. I set the function generator to frq 50Hz and amplitude 400-600 vpp, or DC also I applied and checked the signal on the dashboard and serial oscilloscope both. But, the board produces no reaction and the Vp_Vn channel still gives an uneven sine wave or i guess its noise or something else. I tried so many times but still i'm stuck at this point . Could anyone suggest any solution or PoW ?
  6. Hi, experts: I'm using Zedboard, I try to use JC1 or JD1 to connect to external LVDS port. when I opened VIVADO, choose Zedboard, I can only see push buttons, leds, slide switches. How can I see either JC1 or JD1 so I can set it as PMOD GPIO and then connect it to my LVDS input port. I saw some examples that all the I/Os are supposed to be shown on the board window, but for my project, only a little was there. example board window: my project board window: Thanks Zen
  7. Hi All, Hereby two video's of my ZedBoard with an ad-fmcomms3-ebz daughter board from Analog Devices. Although the AD9361 is capable of much more and this is my first experiment with a SDR I'm exited to show you my progress with this simple demonstration of a FM broadcast modulator and demodulator, using a ZedBoard with Analog Devices ad-fmcomms3-ebz FMC daughter card. Greets, Iw@n
  8. Hello, I am currently working on a project using the Zedboard and some Pmods from Digilent. As of now, I have booted Ubuntu 16.04 onto the ARM core using the Petalinux tools through an SD card. I have also been looking into the GPS pmod and got the bare-metal example to work from programming the FGPA. Through my personal computer (Ubuntu 18.04), I have been able to interface with the Ubuntu 16.04 on the ARM and the GPS pmod. However, I am a little confused as to how the GPS pmod in the PL communicates with the Ubuntu on the ARM. I would really appreciate some insight on the last leg of this triangle of communication. For the bare-metal exercise, I used the IP blocks provided in the vivado-library. I noticed that there were a few files under the driver folder that were related to the software side, but I'm unsure how to move forward. When I rebuilt the Petalinux package with the hdf that included my GPS pmod, the module did not show up on Ubuntu. Do I need to create the hardware driver separate from the vivado-library files? If yes, is that using the petalinux tools or SDK or something different? I have already looked into most of the forum posts and Xilinx documentation provided for the Zedboard, pmods, and petalinux, but did not find an explicit explanation. Thank you in advance!
  9. Hi there, I'm new to the world of FPGAs, and was able to get my hands on the aforementioned Zedboard. I wanted to hook up a camera module to it for some real time processing stuff but I can't seem to find a suitable module. I've looked up PCAM-5c but it isn't compatible with my board although I did find some TerAsic although I'm not sure if they'll work or not. Any thoughts or recommendations?
  10. Hi, I am relatively new to working with the Zedboard. I've managed to get an I2C/I2S audio example working (using bare-metal) , that i've downloaded from here. http://www.zynqbook.com/download-tuts.html Now, I would like to get the same example working using the Linux Kernel. However, I can't seem to be able to access the I2C bus. The bus appears to be there, but denies access. zynq> i2cdetect -l i2c-0 i2c Cadence I2C at e0004000 I2C adapter zynq> i2cdetect -y 0 Error: Can't use SMBus Quick Write command on this bus From looking at the SDK, the I2C appears to be at 0xe0004000 Has any one got any suggestions, or point me in the right direction to find the correct settings..? Everywhere I have googled seem to provide i2c solutions for different boards, or bespoke platform setups. What I don't understand is why it just doesn't work "out-of-the-box" with the default settings. Or perhaps, i have missed something. I am using Xilinx SDK 2018.3, and the Xilinx kernel My kernel settings are these: CONFIG_REGMAP_I2C=y CONFIG_I2C=y CONFIG_I2C_BOARDINFO=y CONFIG_I2C_COMPAT=y CONFIG_I2C_CHARDEV=y CONFIG_I2C_MUX=y CONFIG_I2C_MUX_PCA954x=y CONFIG_I2C_HELPER_AUTO=y CONFIG_I2C_ALGOBIT=y CONFIG_I2C_CADENCE=y CONFIG_VIDEO_IR_I2C=y CONFIG_SND_SOC_I2C_AND_SPI=y CONFIG_RTC_I2C_AND_SPI=y My device tree looks like this: i2c@e0004000 { compatible = "cdns,i2c-r1p10"; clocks = <0x1 0x26>; interrupt-parent = <0x4>; /*interrupts = <0x0 0x25 0x4>;*/ interrupts = <0x0 0x19 0x4>; reg = <0xe0004000 0x1000>; i2c-clk = <0x61a80>; #address-cells = <0x1>; #size-cells = <0x0>; }; The default device tree entry for i2c was disabled, so i've tried different combinations. Any help would be gratefully received Dave

  12. want to buy ZEDBOARD ZYNQ-7000 ARM/FPGA SOC. Will RTL code provided with the board? what do i expect to get? Thanks,
  13. Hey, Can I use Digilent's peripheral "Pmod DA2: Two 12-bit D/A Outputs" on zedboard ? If I check, https://reference.digilentinc.com/learn/programmable-logic/tutorials/pmod-ips/start this link, under Platforms Supported, ZedBoard is not listed. That makes me wonder if I still can use PMODDA2 and other Pmods on my zedboard? IF yes, i think we do not have an IP specificially created for PMODDA2...
  14. Hi all, Would like to find cheaper Zedboard than buying a new one. Would be very taxing to get a new board. Thanks.
  15. Hi all I'm currently working on a project based on ultrasound. I've created a pulsetransmitting board already which hooks into the zedboards FMC-LPC connector (I needed 64 high-speed channels), yet now I need to make a receiving side as well. Since returning signals are in the range of 250-300kHz, I was looking into ADCs of around 1MSps@12 or 14bits. (max. 4 channels needed) Now is the problem that I can't find any spec on the frequency the zedboard PMODs can handle. Is it possible to have speeds of approx 20MHz or is this out of range of the (high-speed) PMOD connectors? Would it be a better idea to make a board with a female-male connector on top of each other so I can pass the signals which need to be passed to the previous made board (as I only need a couple of its transmitting channels, stack the boards with the FMC-LPC connector) and use the other connections for an ADC board, since the FMC should be capable of higher speeds? any thoughts? Thanks!
  16. I'm trying to boot a Zedboard using a SD card, and it fails. The Power good LED is on, but the 'Done' light remains off. I tried 4 different SD cards (all UHS-I), but later read that UHS-I cards aren't supported, so I'm using a non-UHS card and it still fails to boot. MIO6:2 headers are '01100', which is the SD card boot configuration. I've also shorted JP6 on the board. VADJ is at 1.8V The board boots successfully from QSPI - the blue LED and 4 red LEDs come on. I formatted the SD cards using both: the official SD Card Formatter & Windows 10's inbuilt 'Format' Then I copied the 5 files from the Out-of-box Demo on Digilent's website: https://reference.digilentinc.com/reference/programmable-logic/zedboard/start?redirect=1 I've also tried the 'zedboard_oob_design' from the Avnet forums, and the Analog Devices images from their website - and the board still fails to boot. I've tried the SD cards on another Zedboard, and it fails to boot on that one as well. The UART doesn't print anything (115200, 8N1) either. Is there anything I'm forgetting to check? Does the SD card require a specific format, sector size, partitions etc?
  17. Hello i'm using 2 ZedBoards cards with Vivado 2017.4 (for the record - i've tried to work with 2018.1 but from some reason there was a problem with the wifi's library and someone here at the forum suggest to work with 2017.4. link to this post: https://forum.digilentinc.com/topic/17224-pmod-wifi-sdk-problem/#comment-42818 the 2 ZedBoards are connected with the PmodWiFi module, this module has been tested and the hardware is working fine. my goal is to transfer a 120*160 matrix of integers from one zedboard to another. i've succeded to transfer string or several integers between the boards. the project are based on the tcp client and tcp server which exists in the examples inside PmodWiFi library. (also tried the UDP examples, didn't work). i'm sending each time an array of 160 elements. so in total in each transfer there are 640 bytes of data. the function being used is: tcpSocket.writeStream((u8*)mat,160*4)) in while loop until 120 transfers are being made. the current situation is that i'm not getting all the packets at the second card. in average 15-20 packets from total 120 packets are recieved. after a research i've made, i get an offer to put the function -> DEIPck::periodicTasks(); after every write stream but it didn't work. putting sleep(2) after each send also didn't solve the issue. attached a screenshot of the relevant code which will help to explain how the send data works. i'll be glad if someone could help with this topic or refer me to relevant project.
  18. Hey All, I am trying to make a simple IP block design in Vivado 2018.3 to test the ESP32 PMOD out using AT commands for data transmission. I will attach a picture of my current block diagram to this post. I am getting a critical error (reference below) that says the IP has a packaged board value of "digilentinc.com:cora-z7-10:part0:1.0" which is for the Zybo z7 board. My questions are: Q1)Will this design work regardless of this error, as the Zybo and Zed boards are similar and both run off the zynq-7 architecture? Q2)If the answer to Q1 is "no", is there a method of adapting this IP for the Zedboard? (I should be using the latest IP library from Digilent) [IP_Flow 19-4965] IP PmodESP32_axi_gpio_0_0 was packaged with board value 'digilentinc.com:cora-z7-10:part0:1.0'. Current project's board value is 'digilentinc.com:zedboard:part0:1.0'. Please update the project settings to match the packaged IP.
  19. Greetings all, I am new to zedboard. This might be a basic question. I want to send some data via UART0 to DDR memory through direct memory access AXI. (GPS data) Again I want to collect another set of data from UART1 and writing it to DDR memory.(GSM/LTE module) Now if interrupt from one UART( UART1) occurs, I want the processed data of UART0 which is on the DDR memory to be read via UART1(GSM module) and send to a remote server. Any suggestions and advice on how can i design the hardware?
  20. hey everyone, there are hardware & software setup files of AMS101 platform for some Xilinx's evaluation cards i.e. AC701, VC707, KC705 and ZC702. (https://www.xilinx.com/support/documentation-navigation/see-all-versions.html?xlnxproducttypes=Boards and Kits&amp;xlnxdocumentid=UG960) However, I want to use AMS101 with ZedBoard but no idea how to set up. Any suggestions to do that? thanks
  21. Hey, I want to use ZedBoard's XADC for sampling an external analog signal. Only one channel (single channel) is sufficient for now. Therefore, I tried to use the dedicated inputs, namely VP/VN in bipolar mode. When I check USERGUIDE480's page 32, the following picture is given: 1) From this figure, I understand that VN port must be supplied with an external 0.5 DC voltage source. Am I correct? Can i get this 0.5V dc from the ZedBoard not using an external supply source? 2) Is it enough I only connect VP/VN pins of XADC header leaving out other pins unconnected? I mean should I connect AGND or DGND to ground? thanks in advance, mehmet PS: Sorry, I posted this question to the incorrect sub-forum.
  22. Hi everyone, My friend send me his project, but when I open it, it appear this error. All IPs is locked and cannot be customized. He and me use different vivado version. What is the problem ?

  23. Good day! I am designing a board that uses Zynq 7000 SoC and I came across a power management solution from NXP (MMPF0100) that might be the best fit for my application. I would like to understand the entire functionality of the PMIC. NXP had used this PMIC with Zedboard as a design example but haven't shared the entire schematic of the Zedboard using the PMIC anywhere. I request you to share the schematics of Zedboard with MMPF0100 and also the PCB design files, if available. Nishitha

    Axi DMA always busy

    Hi, I'm doing a project that uses AXI DMA. I already done my Ip Core, my Block Design e and my SDK code. The problem is that when my program reaches while(XAxiDma_Busy(&axiDma, XAXIDMA_DMA_TO_DEVICE)) it gets stuck. I'm using a Zedboard and Vivado 2017.4. I did a search, found out that it's a very popular problem, but I had no success solving it, so I'm posting here trying to get more help. I'm attaching my sources. Thank you srcs.zip
