@crosswick Just for my interest, what exact chip or board do you have in mind?

Yesterday I've added a board definition for the E103C8 [here](https://github.com/maxgerhardt/platform-gd32/tree/main/boards) and expanded the SPL blinky and UART example to work with it. If you clone [this](https://github.com/maxgerhardt/gd32-pio-projects), import the `gd32-spl-blinky` project...

Hm okay, can you open a new issue in https://github.com/maxgerhardt/platform-gd32/issues with the output and the used `platformio.ini`? Just to keep the discussion separate from here :)

Update: Me and a group of people (@obra, @howitzer74, ..) have recently started a massive initiative to support GD32 chips in PlatformIO. With * new Arduino Core (already basically working,...

A custom platform integration is available at https://github.com/nigelb/platform-apollo3blue, maybe @valeros can have a look at integration

Above integration is already a PlatformIO integration, with installation instructs in theree. Do you have the board and can test that? (:

@nigelb's platform works nicely on my Sparkfun Artemis ATP 👍  

Will also be extended to compile the Arduino core for the W600 series soon.

@Jason2866 interestingly enough I actually do have such a board and also used the Arduino core (inside Arduino IDE), might have a look at that after that.

Update: https://github.com/maxgerhardt/platform-w60x can now compile the Arduino core for all the same boards the original Arduino core can. Upload via serial works (bootloader upload with PA0 -> GND, RESET) ...
