is this thread really the only mention of GD32 on this ChibiOS forum or is that me failing to use search?

Anyway a bit confused about https://github.com/psycowithespn/ChibiO ... V/issues/1 but interested to leverage the progress done here :)

Hi,

There is a GD32 port in the community repository, not sure how mature it is but most things should be very similar to STM32.

Replied to the issue. Do note that the GD32 stuff on the community repo is RISC-V specific (GD32V*). Others should be compatible with STM32 code.

The GD32VF103 port is stable and I use it daily in my keyboards https://karlk90.github.io/yaemk-split-kb/. The RV-ELIC IRQ handling and context switching code had some bugs but all of them have been fixed. So far I think this port is pretty much done, as the only novell thing was the RV core, periphreal wise this mcu is a f103/f105 clone.
