Serial/UART not working on Linux with the SMF2000

[adrien220615]

Hi all,

(First post, I hope it respects the local habits)

I have a SMF2000 (SmartFusion2) board and I'm trying to set it up with Linux. I've downloaded SoftConsole-v2021.3-7.0.0.599 and I'm running a basic hello world program.

I expect to see a UART file (/dev/ttyUSB0) for the printfs, but nothing appears. I've tried to look into udev rules without success. How do you get the serial output from the SF2 on Linux? (I know the SF2 code is fine, it works perfectly on Windows)

Thanks in advance
