Hello everyone,
I try to implement the ST nucleo f303k8 board for the zephyr framework. I started with the official zephyr repository. I successfully implemented the board, the soc and the dts for the f303x8 series. I was able to build the board with the hello world example using the CLI tool west and the zephyr sdk. Now I would like to integrate the new board to the awesome vscode extension PlatformIO. I used the nice guide to add the custom board to PlatformIO.
First issue I had to solve was to add the new mcu in the “framework-zephyr/soc/arm/st_stm32/stm32f3/Kconfig.soc” file with:
config SOC_STM32F303X8
bool "STM32F303X8"
select CPU_HAS_ARM_MPU
I tried to put the modified Kconfig.soc with the new soc into the zephyr project folder but that would not solve the issue. How can I solve that so I don’t have to modify the original framework file?
After temporary fixing the first issue I get some cmake errors I am not able to solve.

I looked at the “/home/sebastian/.platformio/packages/framework-zephyr-hal-stm32/stm32cube/CMakeLists.txt” file and there is some logic to decide which mcu driver the compiler should use.
I guess that in some point cmake misses to pass the mcu type or it is missing at all.
What I don’t understand is why the config is building with the zephyr SDK and the tool west but not with PlatformIO.
I put the whole project with the CMakeOutput.txt and the CMakeError.txt into my dropbox so you can test if you can reproduce this error.
My system specs are:
Linux Mint 19.2
vscode version 1.51.0
PlatformIO version 2.2.0
Thanks in advance for the help and the awesome PlatformIO extension.
