  1. 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.
  2. 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
  3. 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?
  4. 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 VHD

    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
  6. 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 fo
  7. 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 bo
  8. 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 d

    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 :)
  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. 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.
  12. Hello While I was working on ZedBoard with USB-JTAG, the USB port suddenly broke apart. When I contact the USB port pins with the board pins, I can still do stuff, but I want this port to be fixed to the board. So I requested RMA to my seller but she told me that the warranty period is over and guided me to post a question in this forum. I bought the board on Oct 05, 2018. Any way to get this broken port fixed?
  13. @Bianca @Rainer Urian can you help me ? i am also working on zybo board and suffering from same problem. my usb port ( j10 and j9 ) are not getting detected . can you tell me how to resolve this issue ?
  14. Hello everyone , I'm realtively new in programming FPGA's and needed some help . My micro-usb port got shorted so i had to resort to programming my basys-3 with a usb drive . I followed the reference file from digilent on that and everything was working fine . I used it the same way for the next few months . I stopped using the board for a months after and when i tried programming it today again , the bit file did got programmed . INstead the busy led next to the port forever keeps blinking . I tried formatting with FAT32 , resetting , testing the demo file on QSPI but noth
  15. Hi! We are working with a Basys-3 FPGA and were wondering if it is possible to read large data files from a USB stick. We are trying to let the Basys 3 produce music through a module, but the internal ROM/Flash storage of the Basys is too small for, for instance, .Wav files or .Wav converted to .coe files. Is there a possibility to use the USB stick support for programming for this application or perhaps another method? Thanks! Kind regards, Jonathan
  16. So my current project is very simple, but I've yet to settle on how the control logic is going to be implemented. I think the FSM and Microblaze are both perfectly viable solutions, but I want to find the intersection of maximum learning and minimum complexity. The controller will be performing three tasks: -Pass alternating I and Q data from another module via usb to the user. -Receive data from the user via usb to set a desired frequency. -Interface with the clocking manager to request the new frequency. I am sure I could create an FSM to accomplish this, the USB controller h
  17. Hi, We are going to purchase JTAG-USB Cable to debug our own developed chip. 2 questions here: 1. I assume this JTAG-USB Cable is able to auto-sense my VDD voltage level as long as it is within the range 1.8V ~ 5.0V. Is this correct? 2. We need this JTAG-USB Cable to do some configuration in our chip. Do I use "Digilent Adept Suite" or "Digilent AVR Device Programmer" to generate my JTAG signals/waveforms ? And one request: 1. I need a datasheet of JTAG-USB Cable datasheet if possible. Please advice, thank you. Tifei
  18. Hello, I just opened my new basys3 board (novice EE student). As per the documentation I tried to power the board via usb-b (port j4) first through a laptop usb then through a 5v 2A charger making sure the jp2 jumper was set on usb and jp1 to the spi flash test program but the board did not turn on (not even the power good led). Trouble shooting that I performed: 1. Changed cable twice (didn't work) 2. Changed charger and usb ports (didn't work) 3. Powered board from external 5v power supply - the board worked perfectly. My question is could the smd sold
  19. Good day everyone! I need help on programming the Nexys 3 using a USB memory stick. Here is what I tried so far: 1. Save a single .bit file to a USB memory stick. I have tried my own .bit files as well as the Digilent's Built-In Self Test. I have also tried two USB flash drives. 2. Connect two jumpers on the mode switches. I have also tried none and mode 0 only. 3. I then attached the USB flash drive to the Nexys 3 and press the reset button. But unfortunately the bit file does not get programmed to the FPGA.

  20. Hello, my friends, i am new here and it is my first project. This project will be my BSC. I have to make next: 1. Make USB CAM interfacing on System Level using systemC... My diagrams are shown in the post. I need to capture the photo using a USB CAM. After that, the picture needs to be stored in some memory. After that the image processing logic (In my case, the logic needs to have the photo (stored in memory) as its input, the idea is just to decrease the photo size (pixels) and the output is the result (decreased size picture)), after that the result of processing needs t
  21. Regarding: Zybot Project I am having an issue getting the USB WIFI Adapter to successfully connect to the internet. What is working: 1) Micro SD card Prepared for Boot on Zybo 2) Successfully able to boot and login to linaro 3) Connected a 4:1 USB hub to the USB port on Zybo and all ports are working - Tested this by connecting 1 mouse on all 4 ports, (one at a time) and the mouse works on all 4 ports 4) Camera is working fine, (motion is installed, server scripts copied to init.d and permissions changed) 5) Able t
  22. Hi, I'm running Arch Linux (https://archlinuxarm.org/platforms/armv7/xilinx/zedboard) on Zedboard and I'd like to use the OTG-USB as a host, but my Zedboard doesn't seem to detect the device plugged in (I've tried a USB flash drive). What are your suggestions? I've followed the instructions on http://zedboard.org/sites/default/files/documentations/GS-AES-Z7EV-7Z020-G-V7-1.pdf , but Zedboard just won't see the device.
  23. HI, for my new PYNQ-Z1 to connect over its "USB HOST" interface: (1) will any USB Hub do, e.g., when concurrently a USB WiFi dongle and a USB-Webcam are connected to the PYNQ-Z1? (2) what is your recommendation(s) of a "compatible" stereo camera module (cf. attachment) for the PYNQ-Z1 board ? Thanks.
  24. Hi FPGA gurus ! I am facing trouble while trying to attach my Atlys USB JTAG device to a Centos 6 virtualbox VM. I recently had no choice but to upgrade my computer from Windows 7 to Windows 10. As a Windows 10 version of ISE 14.7 was available, I decided I could do the upgrade before realizing that ISE 14.7 for Windows 10 was indeed ISE 14.7 for Linux running a VirtualBox... Nevermind. The problem is that it seems I can't attach Digilent USB JTAG to the VirtualBox. Here is my configuration : Windows 10 Pro VirtualBox 5.2.8 (I upgraded it so that I could install Extensions
  25. hello, I am interested in the following reference design: https://reference.digilentinc.com/learn/programmable-logic/tutorials/nexys-4-vga-test-pattern-with-mouse-overlay/start The design currently does not provide any sources: Is this project abandoned? I believe it had not been updated since 2015. Is there a later version available (this one, perhaps, or on github?) I am interested in the USB host with mouse, which I intend to implement on the Zybo/Zybo-Z7. Do you provide the sources for this project? Is there a project you can recommend, There is also the BIST for t
