Interesting, at the time I looked at this, Zephyr didn't support anything **Gigadevice** related, but now it seems to have better support for **some** boards: See "gd32" in https://github.com/zephyrproject-rtos/zephyr/tree/main/boards/arm. Which...

>I'm just treating the mcu like a STM32 from Zephyr's viewpoint And what mapping from GD32 to STM32 are you using there?

Hm, looking at the memory map for [GD32F303xx](https://github.com/CommunityGD32Cores/gigadevice-firmware-and-docs/blob/main/GD32F30x/GD32F303xx-Datasheet-Rev1.5.pdf) page 15 and [STM32F103C8](https://www.st.com/resource/en/datasheet/stm32f301c8.pdf) page 51, they are different in e.g. already GPIOA peripheral address. But RCC, UART, I2C and TIM are...

I treat my GD32F303CC with the `stm32f1x.cfg` config file. Sources like https://www.eevblog.com/forum/microcontrollers/psa-gd32f303-is-not-a-drop-in-substitute-for-stm32f303/ also say its more a STM32F103. Your current problem might actually be flash protection and I've had that...

>for some reaosn PlatformIO only showed me the Link for Remote Update That's weird. Can you restart VSCode again and show a screenshot of the available project tasks?

Sounds great! I also dropped some notes earlier in https://github.com/MarlinFirmware/Marlin/issues/21473 asking what makes sense that we do on our side. We have a discord server linked at https://github.com/CommunityGD32Cores/ArduinoCore-GD32#collaborating as communications...

I'm not sure about this -- wouldn't we be doing duplicate work that https://github.com/sipeed/platform-gd32v has already done? What are is that platform missing, feature wise? I see the RISC chips...

And when we have SPL support, won't people also be asking for Arduino support through https://github.com/sipeed/Longduino? Or should we adapt https://github.com/CommunityGD32Cores/ArduinoCore-GD32 to also support the RISC-V chips?

The SPL is indeed maintened from the Gigadevice side, but the sipeed paltform references https://github.com/sipeed/platform-gd32v/blob/master/platform.json#L43-L48 and that was last update a whopping 3 years ago (https://registry.platformio.org/tools/platformio/framework-gd32vf103-sdk/versions), so richard has a...

We have not yet adapted [genpinmap](https://github.com/CommunityGD32Cores/platform-gd32/tree/main/misc/scripts/gd32_genpinmap) to work with this type of chip that would auto-generate the needed Arduino files, but we plan to do so. However, we do have...
