  1. Hello. I believe similar questions are present on the forum before mine. But I specifically want to know aside from the peripherals difference (RAM, SDCard, VGA etc.), is it ideal to assume the HDL designs (except the peripherals IP) would be compatible with both of them if one is supported by some project. For instance, lowRISC has a guide based on Nexys for its core booting Linux (https://www.lowrisc.org/docs/untether-v0.2/fpga-demo) whereas SiFive E310 has been demonstrated on Arty. The LiteX project supports both the boards (at least from the code base it looks so). Can s
  2. Totally new to all this. 73 year old grandpa, retired engineer, returning to grad school, microelectronics concentration. Lots of technology catch-up to do. So, starting with VHDL. I must self-teach VHDL and need my first FPGA. Can someone help me understand these 3 possible choices for someone in my position: (1) Basys MX3 PIC32MX, (2) Nexys A7-100T, (3) Zybo Z7. Don't want to buy anything too complex, but I have to get the basics with ability to grow. Many questions about compatibility, accessories, programming... Can you help me get started?
  3. I had left my board connected to my laptop and power to the board was abruptly cut off when the laptop died. I tried to connect the board to a different computer and realized that it no longer turned on. Though, the computer's device manager shows that something is plugged in. Yet, adept and vivado are unable to recognize that a device is connected - on vivado I was planning to restore the board to it's default setting using a .bin file but received the following error message: ERROR: [Labtools 27-2269] No devices detected on target localhost:3121/xilinx_tcf/Digilent/210292AA77E6A. Check cable
  4. Hi, I have a Nexys A7-100T board. I want to supply voltage using external battery pack for my measurement. But for my measurement setting,voltage supply line has 6.5Ω resistance.When I supplied 5 V to voltage supply line, FPGA coundn 't activated. I guessed the reason for activation problem is voltage drop. I supplied about 7.25 voltage so that voltage between battery’s positive terminal to the center pin of JP3 and the negative terminal to the pin labeled J12 is about 5 voltage.I checked the center pin of JP3 and the pin of J12 is about 5V. But I coundn 't activated.
  5. I am trying to operate the Nexys Video development board using the vivado hardware manager on a windows 8 system. However I keep getting No hardware targets exist on the server error. Steps i have taken to remedy the situation include: Re-installed Vivado with included cable drivers Tried different versions of vivado Tried on a different PC Formatted PC and installed vivado Updated FTDI drivers Tried 3 different (new) USB cables Installed cable drivers manually The programming jumper is in the right position (jtag), the USB cable is plugged into t
  6. Hello, We are looking at evaluating the Nexys video board for a new electronics platform for our company. I was wondering, are the source files for PCB layout design available to customers? Also what is the operating temperature range of the board? Thank you, DB
  7. I have been following this tutorial and have had no luck. I am uncertain about how to configure the QSPI IP, because the tutorial starts assuming that I have done that part successfully, so I am not even sure if this is the root of my problem. I have tried these two configurations of this IP, compiled them, and exported them to the SDK, and none of them solved the problem: I made sure JP4 is in the QSPI position. On step 3.1 in the tutorial, I can see that the FPGA is programmed successfully and I see the following output (since I chose not comment out the VERBOSE define as su
  8. Hi, I am am able to compute the FFT using IP core block available in Vivado 2017. However, whatever is the sample rate of input signal to FFT IPcore, the frequency resolution of the FFT is fixed by clock frequency of the FFT. Example Frequency resolution = sampling frequency/number of samples DDS compiler generates sinusoidal frequency 976.56Hz at a clock freq of 1MHz,therefore the sample rate is 1Ms/s. this signal is given as input to the FFT IPcore 9.0 which is clocked at 5MHz with number of samples as 65536. therefore, Expected frequency resolution = 1MHz/65536, however
  9. Hi, I have been looking on the Digilent site for a while now but I haven't found what the maximum operational temperature of the Nexys Video board is. I use the board to test another in house developed board but I need to run a thermal test at 60°C. Is this possible with the Nexis Video? Kind regards, Oceley
  10. Good morning, I am currently using the uart protocol to communicate my Nexys 4 DDR with Matlab, but I have the inconvenience that I need to send signals of more than 8 bits, someone knows how to receive matrices in vhdl by uart (something like the function fread de matlab). Thank you for your attention
  11. Hello, I'm trying to understand the HDMI capabilities of the Nexys Video Artix-7. I don't own a board yet, so these queries are based on reading spec sheets; please excuse any errors or omissions on my part. The FPGA on the Nexys Video is XC7A200T-1SBG484C, which supports 4 GTP transceivers at 3.75 Gbit/s [1]. However, based on my best interpretation of the Nexys Video data sheet [2] the HDMI ports aren't using the GTP transceivers. The GTPs are used for DisplayPort and FMC connector. Given the HDMI ports aren't using the GTPs, what is the maximum data rate the FPGA can su
  12. Good morning everyone, I am currently developing a computer application in Matlab with help of VHDL and the Nexys 4 DDR, my problem is that I need to send a vector of 16 or more bits through an aurt module, the aurt module only sends 8 bits but I need to send more bits. anyone have any idea how to receive more than 8 bits per aurt? , I know that you should make the matrix reception module in vhdl and I was trying with this module that I have, but it does not work, and I have no idea how to do it to receive matrix. thanks. recepción.txt
  13. Good afternoon someone knows how to implement a UART communication protocol in l nexys 4 for the XADC, someone who can explain it to me and how to implement it?
  14. Hello! I'm newbie in xilinx, and I have one more problem with microblaze with ddr3. I want to have access to DDR3 memory in my MB processor, without processor caches. I implement some design, write very simple code: #include "xparameters.h" int main() { int a = 0; for(;;) { a++; } return 0; } and I can't start debug ... When I start debug, it don't stay at main (but, thread is still running). When I pause it, I see in disassembler what processor stays at _hw_exception_handler In attach you can see system, linker mapping, and problem.. Pl
  15. Hello! Where can I find the sourse of demo project for Nexys Video Board? I don't see the archive link on the official website. There is a problem with an OLED display. The official datasheet doesn't have a table of command system. That's why I'd like to have a look at you demo-project. UG-2832HSWEG04-Univision Technology.pdf
  16. Within the schematics of the NEXYS 4 and NEXYS VIDEO boards I couldn't find the part with the Micro-USB JTAG bridge. The part with the FT2232HQ chip is left out in both schematics. Is there a reason for neglecting those parts? Could I find the schematics elsewhere? I'm especially interested in the differences between a combined JTAG and UART Micro-USB solution (as seen on NEXYS 4) and two separate solutions Micro-USB JTAG (1) and Micro-USB UART (2) (as seen on NEXYS VIDEO).
  17. In my lab at work we are using a stash of old Nexys 2 boards for a prototype project. I need to verify the exact part number of the Hirose Fx2 connector, because it's highly embarrassing when you drop $20k on hardware and the cables don't mate. I have looked through the official docs without luck, and appreciate the help. It seems to me it's a FX2-100P-1.27DS. Correct? Many thanks!
  18. Hi, At the start of the year I purchased a Nexyss 4 DDR board from Digilent. I hadn't used it until a few weeks ago, but now am using it for a university project. However, I have discovered two issues with the board while using it. 1. Switch 3 (of the sliding switches), is faulty. The switch will sometimes read as "on", even when the switch is in the "off" position unless it is actively pulled back. I can verify that this is not a coding problem because it happens when the device boots into the default program (loaded by digilent) and all other switches work. 2. Transistor
  19. Hi, I am looking to buy a board of the Artix-7 family and trying to choose one between Arty, Basys 3 and Nexys 4 DDR. I have the following questions. 1. Is it true that the Vivado software that comes with Arty can only be used for one year since Arty is an evaluation board? 2. Is it possible to install the Vivado software on different computers and work on them (using the same board)? Does this behavior differ in any way among the three boards mentioned above? 3. I am confused about the number of cells in Nexys 4. On Digilent's website, it says Arty & Basys 3 both have about 33K logi
  20. Hello everyone, I am using a Nexys 4 DDR for a school project. I am building a system that uses a video camera to detect and track human motion. Several questions: 1. Which port should I use to connect the camera? The immediate one available on the board is the USB host connector, but is it possible to use it to connect a camera? 2. Are there any PMODs available to connect a camera module? 3. Any recommendations for a specific camera model to use for this project? Basically, I need to take the video input, perform some filtering to recognize face and arms, downsample t
  21. My goal is to send data from the fpga to the pc using DSPI. This data, in this case RGB data, gets transformed into video using Unity. There are, however, several problems with sending data from the fpga to pc. Currently the pc is receiving data from the fpga as follows, From the pc side: Open the device (NexysVideo) using the function DmgrOpen(&hif, "NexysVideo") Enable DSPI transfer using the function DspiEnable(hif) Set the SPI mode using the function DspiSetSpiMode(hif, idMod, fShRight) Set the master (pc) clock frequency using the function DspiSetSp
  22. Hey all , I am taking a continuous 16 bit serial input from an AFE to nexys 4 ddr board and storing it . Now I have to take this data to pc using usb . I have been searching for this for a long time now (2 weeks to be exact ) but could not find any simple solution . I am using ISE design suite 14.7 VHDL for programming. This is my first fpga project, so please bear my incompetence. Thank you
  23. I have implemented the DDR3 on the Nexys VIDEO as shown in this tutorial https://reference.digilentinc.com/nexys-video/gsmb so my question is how can i mofidfied the IP MIG for reach 800 Mb/s on the nexys video? when i open the IP for modified teh parameters in clock period i set 2500 ps, input clock period 1250 ps (800 MHz), system clock : No buffer, Reference clock: Diferencial, clk_reference with pin number R4/T4, so when i run the synthesis occurs a problem in the clk_ref Note: some of the setting of my IP MIG In this part i connect the pins R4
  24. I am trying to run a microblaze project on the Nexys video development board. However I am having cable driver issues and thus I am attempting to apply the design using a USB host (using a pendrive). I am able to apply a design with simple vivado hardware designs and that works fine. However I cannot get the sdk code for the microblaze to run. Currently I am using the download.bit file generated by the SDK. This bit file is generated using a bootloop. I am following this tutorial (https://reference.digilentinc.com/nexys-video/gsmb) and so the design should not be the problem. My que
  25. I plan to use Nexys video for image processing. I did a project before where the FPGA gets the data straight from the sensor but now I will be using one of the interfaces (HDMI, USB, etc). There is a number of options, probably any of them valid, I'm just asking for suggestions. The most available cams have USB interface but Nexyx does not have 'pure' USBs unless I'm wrong and I'm not that much willing having an embedded processor just to interface USB to my video format stream. Second thing I though was to use the HDMI input but can't find many cameras with that output... Of course I want to
