    fpga programming using Ubuntu 18.04

    amamory

      Hello,

       

      I am testing a mini-itx board with Ubuntu 18.04 host OS.

       

      The tests with builtin software went ok. However, when i try to program the FPGA via this module

      https://store.digilentinc.com/jtag-smt2-surface-mount-programming-module/

       

      The USB device is not even recognized. I checked with 'dmesg' command. Nothing changes when i plug the usb in or out.

       

      It seems that there are 2 possibilities:

      1) there is a special device driver for https://store.digilentinc.com/jtag-smt2-surface-mount-programming-module/

      2) there is some jumper to allow jtag programming that I am missing.

       

      Reading the manual, I see that SW7[1] enables the JTAG Cascaded. I switched this on and off and nothing changes. The USB port is not recognized.

       

      So, what is necessary to have the USB JTAG working on Linux ?

       

      best regards,

      Alexandre
