  1. The USB plug was yanked on one too many times and started failing. When it was broke more than it worked, I fixed it enough that I could use the board. I ended up fixing it a couple more times but the last time there just wasn't enough left to succeed. It really sucks because that board was central to so much of getting hobby projects going. It lived a mostly good life since I bought it back in 2011 an I'm not ready to say good bye. Unless I can get the interface back, it's just a breadboard (a pretty one tho!) so I'm open to try anything if there's a chance. I'm hoping that there are some solder pads on the bottom that can be accessed, maybe if some supporting electronics or something were in place. Or there's a secret backdoor JTAG if you plug lines in to the right combination of board outputs? Anyhow, if there are schematics anyone has for the USB area, I'd love to see them. Please help!

    USB to JTAG module

    I am hearing some modules are going obsolete. Which module should I be purchasing if I were to use it with Vivado 2018.3?
  3. Hi everyone, I was trying to solve a persistent problem on my Analog Discovery because at first it had a worn USB contact so I replaced it with a spare part, expecting it to work properly, but apparently now it has a short-circuit. When I connect it to USB, it consumes about 640mA of current from my computer's USB. I tested it with a phone charger with higher current capacity as well and it also consumed 640mA. When trying to pinpoint where is the problem, one of the components between the FTDI chip and the USB connector heats very much. I would like to know which are the values of those components so I can repair my Analog Discovery device. Thanks.
  4. Hello everyone, I'm currently working on a bare-metal USB host project on the Eclypse Z7 platform, utilizing the USB Micro AB connector (J5) present on the board. PL is already set up to be able to use the USB 0 adapter, but the example code provided with the "usbps" driver only seems to cover DEVICE-related applications. Is there any HOST example available, or can anyone provide some guidance on the necessary steps of setting the USB host up? I'm just not able to get it up and running. I'm glad for any advice. Thanks.
  5. We have a Teledyne T3PS3000 programmable supply connected as USB client to ADP3450 running in linux mode. The serial connection is detected and reports something along these lines in the terminal: The power supply can accept text-like SCPI commands to change power supply settings and modes. How can we issue commands to the port? Either through Waveforms or the linux shell? Can't seem to find it as a generic serial device that we can just echo commands into... Ultimately we would like the power supply configuration parameters to be part of our automated testing.
  6. I am interfacing between a USB IC (a FT2232H FTDI chip) and a EEPROM IC (a 93AA56BT). To make the FTDI chip recognizable by Xilinx tools I need licensed Digilent Serial Numbers. How can I get a licensed serial number file to enable a USB-JTAG FTDI interface? Are these licenses keyed specifically to your chips? How can I enable a JTAG-USB FTDI interface?
  7. I have some problems getting started with the ad2 board. When i plug it into my laptop it doesn't get recognized. In fact, the computer doesn't even realize that a usb device is plugged in. It is also not found in the device-manager. When i open the waveform software it shows "no device detected". I have tried switching usb cables, different usb-ports, restarting the laptop, different laptops and changing the usb settings. What else can i do? I also want to mention, that the board was succesfully used by someone else before. Thanks! Johannes
  8. Hi everyone, so I have a atypical question about J17 port. So accidentally I damaged it, because the board fall and the micro usb cable was connected to PROG port so the board throws the port and causes a physical damage on it. I want to repair it, resoldering the port, because it’s more practical carry a Micro USB cable instead a JTAG to USB converter to program. So if you can help me with the verification of the connections. For example the USB OTG port J13 looks like all the pines are used although the UART port J14 looks like only uses 4/5 pines. I attach the photo of the crime scene and if someone could help me about the connections of the died points. Thanks a lot. ??
  9. Disclaimer: I'm not an expert, just a student working on a school project. My zybo z7 board stopped showing up as /dev/ttyUSBx on my linux vm when connected using the UART microUSB port. On my windows host the com port does show up but I cannot open a connection with putty (115200 8n1), no error info or strange characters, just an error sound effect with no explanation. I tried everything on the pc side (driver reinstall, reboot, enable/disable port, different ports, different cables) but I suspect that it is the board not communicating. I use external power with WALL selected and booted from an sd card with a 500 mb fat32 partition with a boot and image file generated with xilinx petalinux which were not changed from when everything worked fine. There is also a 3gb ext4 partition where the fs is. The only thing that changed before the problem occured is that a few to-be-tested precompiled kernel modules where added to the ext fs in the home folder. Other students with the same set-up do not have this problem. I tried different sd cards and remade the partitions and redid the boot/image/fs generation but no success. When booting from QSPI the example program works fine so I don't think the board is broken (The serial com doesn't work in QSPI either but I don't know if it's supposed to). Maybe it needs some kind of factory reset? Is there a way to confirm if the microUSB port is working? Help will be appreciated. btw: upon startup I can see the RX led flickering but never the TX led
  10. Hi Digilent staff, and fellow forum members, Just wondering if you guys had considered making a USB HID -> PS/2 PMOD board? I was thinking of something like the circuit on the Nexys 3,4 boards which uses a PIC to convert a USB keyboard to PS/2 compatible signals. Would be handy for using newer USB keyboards/mice on PMOD socket equipped FPGA boards. PS/2 devices are becoming harder to find brand new. I (for one) would be interested in a few. Kind regards, Leslie
  11. Hello Everyone, We have develop simple imaging system based on Nexys Video development board. We have interfaced Sensor with VGA/QVGA resolution using PMoD ports which provides Monochrome 14-bit data and we are sending this data on Ethernet using UDP packets on PC. We have designed our custom UDP protocol for sending data. Currently we are having Nexys Video board but as per data-sheet this USB port is used for storing programming file. Now we would like start development of similiar imaging system with USB output port. We are new to USB development on FPGA. Can you please share us how to proceed.? How to get started with USB design in Verilog? Is this possible on this board?
  12. Hi All, I'm working on a project that requires me to read a file from a PC (mac, windows, or linux), or external thumb drive onto Xilinx Zybo Z7 board. The communication does not have to be over USB however it does have to be able to read a file either on a USB or a Computer as well as write to that same device. I've looked at several different forums and can't find anything that would make this seem doable. Any help in this matter would be greatly appreciated, thanks for your help. If you could provide an example of a small working project that would be immeasurably helpful.
  13. Hi, I am using windows OS and want to know the use of USB port on Zybo board. I have no idea how it works. Can I able to implement using verilog or I must need Zynq processor? I appreciate if anyone have sample project which will describe the use of USB port using zybo board on windows OS. BR ALI
  14. Hi! Is there an example project for transferring data to the PC via USB 2 for the old Nexys 2 board? I was googling as well as looking on the documentation section of this website and I couldn't find anything. I need a bitrate of at least 4 megabits/second, so serial port emulation will be insufficient. I don't care about sending data to the board, just receiving. It would be great if it was specifically for the Nexys 2 but I understand that since it's old there might be nothing, so is there a tutorial/example project for a similar board I could use as a guide? I'm still fairly new to VHDL. Thanks for your help!

    USB audio on PYNQ-Z1

    Hi there, I am pretty new to using the pynq-z1 board. I wish to do some audio recording via a usb microphone! I am struggling with doing this successfully, is anyone able to help me with this? I am getting "no soundcards found" when issuing alsa commands arecord -l and aplay -l. I understand pynq -z1 receives audio samples as PWM or PDM, but im not sure exactly what that means in terms of linux drivers available. any help would be appreciated! Thanks
  16. Hi, I have a recently buyed a Zybo board and wanted to use it with Vivado 15.1 on Windows 10 I installed the cable drivers but the USB cable did not appear in the Windows device manager. Only the Jungo Windriver is there. It seems as would the FTDI chip be invisible for Windows. So, I assumed it is either defect or misconfigured. Therefore I tried to use the FTDI tools like FT_Prog to check the FTDI chip on the USB port. But still no luck. This tool doesn't work. It complains that FTD2XX.dll is missing. This DLL will not be installed by the Xilinix cable driver form Vivado. Therefore I tried to install the drivers form the FTDI site. This worked without errors, but FT_PROG nevertheless complains that FTD2XX.dll is missing. Then I copied the FTD2XX.dll directly to the FT_PROG installation folder. The "FTD2XX.dll is missing" error is gone, but the tool shows me no FTDI device. Any ideas? Rainer
  17. Hello, I am currently working on refurbishing an existing programming bench using the Nexys Video™ FPGA Board Development Kit. Requirements for the test station require that I must use direct Tx/Rx RS232 data communication to the Artix-7 FPGA without the use of the FTDI FT232R USB-UART bridgeUART/Serial Converter Interface as described in the user manual. This used to be achieved with a now obselete Spartan-6 FPGA development board that provided a direct RS232 Serial Port on board. I cannot recall the exact model # for the retired board. Is there any way I can input RS232 data directly into the Nexys Video FPGA Dev Kit without the use of a USB/UART Bridge? Thank you

    Firmware via Android

    Hello, we are looking for help to write our FW on Spartan6 via USB port & Android app, our tablet have USB type A standard ports, also type C port. We need to write it like we do from Windows Impact software, can someone help us with that? thanks :)
  19. I am interested in buying Spartan-7 FPGA Module: https://store.digilentinc.com/cmod-s7-breadboardable-spartan-7-fpga-module/ but first I would like to know if it suffers same USB cable issue as CMOD-A7: Since FTDI circuitries look similar on these two boards I just want to make sure the faulty design was not copied over from A7 onto S7.
