Nexys Video - Firmware for onboard USB JTAG


Is there a way using Vivado 2019.1 (or other tool) to read/update the firmware of the USB JTAG PIC processor?  Our process requires that we identify all programmable components and confirm that any non-volatile memory is configured as expected.  Using Xilinx iMPACT software the following information is reported after connecting to the Nexys Video A7-200 (410-316) board,

  • INFO:iMPACT - Digilent Plugin: Plugin Version: 2.4.4
  • INFO:iMPACT - Digilent Plugin: found 1 device(s).
  • INFO:iMPACT - Digilent Plugin: opening device: "NexysVideo", SN:xxxxxxxxxxxx
  • INFO:iMPACT - Digilent Plugin: User Name: NexysVideo
  • INFO:iMPACT - Digilent Plugin: Product Name: Digilent Nexys Video
  • INFO:iMPACT - Digilent Plugin: Serial Number: xxxxxxxxxxxx
  • INFO:iMPACT - Digilent Plugin: Product ID: 01600155
  • INFO:iMPACT - Digilent Plugin: Firmware Version: 010F
  • INFO:iMPACT - Digilent Plugin: JTAG Port Number: 0
  • INFO:iMPACT - Digilent Plugin: JTAG Clock Frequency: 10000000 Hz

I assume the that the Firmware Version (010F) is referring to the USB JTAG firmware. 


  1. Is the reported Firmware 010F the USB JTAG firmware version?
  2. What is the recommended method for reading the version \ update the embedded USB JTAG firmware?
  3. I understand this is not a Xilinx forum but is there a known method to read\update the firmware using Vivado or using any of the installed Digilent plug-ins?

Thank you.

Hi @Goodbye,

I apologize for the delay; to clarify, you are inquiring about the material on the FTDI chip downstream of the microUSB port (J13)? Or the USB HID port and it's PIC24 (J15)?

Presuming it is the first one, there is not a way to change the firmware through Vivado or installed Digilent plug-ins, though it is very possible to overwrite the EEPROM on the device with FTProg and cause it to no longer be recognized as a programmable device by iMPACT or Vivado.
