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
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 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 ?
