I built you a minimal config, could work like this, maybe I mixed up RX/TX, but it's a good start :)
Code:
odippel@odippel:/usr/src/riocore$ PYTHONPATH=. bin/rio-generator riocore/configs/TangNano9K/config-mecanix.json loading: riocore/configs/TangNano9K/config-mecanix.json loading board setup: TangNano9K writing gateware to: Output/Mecanix/Gateware !!! gateware changed: needs to be build and flash ||| loading toolchain gowin writing linuxcnc files to: Output/Mecanix/LinuxCNC odippel@odippel:/usr/src/riocore$ ls Output/Mecanix/Gateware/ blink.v      hash_new.txt  Makefile  pwmmod.v  rio.sdc  stepdir.v  uart_baud.v  uart_tx.v debouncer.v  impl          pins.cst  rio.gprj  rio.v    toggle.v   uart_rx.v    uart.v .... PYTHONPATH=. bin/rio-test riocore/configs/TangNano9K/config-mecanix.json /dev/ttyUSB0

I'm sorry, I was a bit bored :)

O M G. Wait, are you showing us that all what's missing to RIO to be fully functional is a fpga dev board and the toolchain installed? As in "screw Gowin IDE'??? If that's the case then that's a pretty serious game changer.

I have so much to learn about your solution, obviously. Excitement is getting outta control!!

I just wanted to show that it is not that difficult to support new boards.
It is a bit more complicated to create the board with a picture and the correct pin positions for the setup tool, but this is only optional.

If the toolchain is already supported, it is quite easy,
copy a similar one and adjust the values (type/clock-speed and pin).

One word, Oliver; EPIC.

Let me learn what you've done for yourself and all of us first. This will require time on my side, but will be worth it I have a feeling - "it works" (see visual)!! I'll update on progress and hopefully can contribute what was done at my end. Interim, let me know if you need the sources/gerber/bom/anything for the dev board in use. Better yet, let me know what else could potentially go on it to make it a "RIO-BOARD" (RTL8111H?!) and I'll see what I can do.

Stupid me... I could have cloned/checkout the 'dev' branch rather than main and use what you've done already.
Explains why I couldn't find it locally lol. Let's try that again.
