Hello,

I am developing via a CMake project in VSCode. My build environment got corrupted by trying to mv/rename firmware folders via git. Now i cannot build anymore.

build finished with error(s).

 

I already tried deleting the build folder via `rm -rf build/Debug`

and then regenerate CMake `cube-cmake -S . -B build/Debug`

After that i regenerated the CubeMX project. 
The error persists. 

It looks like CMake is trying to build for an M4 instruction set, despite me having setup H7 in CubeMX.
It worked like a charm before. I am really stuck, would appreciate some help!

Hi @95lux 

Did you made the right adjustments in the Cmakelists.txt file to point on the new FW ?

Sorry, this can be closed. Was a dumb CMake error on my side. 

I had to include the correct toolchain file, when regenerating the build env:

cmake -S . -B build/Debug \
 -G Ninja \
 -DCMAKE_TOOLCHAIN_FILE=./cmake/gcc-arm-none-eabi.cmake

 Thanks for replying!

Additionally, you can rely on CMakePresets.json, which should already define the toolchain file and the generator:

cmake -S . --preset Debug
cmake --build --preset Debug
