- Are there makers in the forum using Ubuntu on Windows Subsystem Linux to compile MakeCode bootloaders for STM32 devices (i.e. F030, F103, F401 etc.)? - May I ask how did you setup the STM32 libraries for compilation? - What is the easiest method to compile for STM32 when running on Windows 10? ---

This is a question for @mmoskal. ---

I got it to work some time ago with the Ubuntu on WSL2. I don’t think there’s anything special - you just need `arm-none-eabi` in your PATH. The BMP debugger will probably not work with WSL though… ---

Are you using libopencm3 and GCC for STM32 development in MakeCode? ---

GCC yes, for all embedded development. libopencm3 I only used in bootloaders, since they were based on existing bootloaders. I usually use STM libraries. The codal is mostly using the HAL [https://github.com/lancaster-university/codal-stm32](https://github.com/lancaster-university/codal-stm32) and I’ve been working on new JACDAC implementation for STM32F0 with the LL STM drivers (which I would recommend over HAL). ---

not using WSL, but WSL2. Basically I run my own distro on it, but it does not need anything special… Note: WSL is not ideal (either run a VM or WSL2, which is technically the same). ---

How did you setup your compiler toolchain? I need some tips here. ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/1X/11322e1997778080680e59c46766f7ca442fb1f6.jpeg)
