Hi, 
I have just installed STM32 Cube IDE 2.0.0 for Mac OS Apple Silicon, and then installed the GCC ARM for STM32 10.3-2021.10 toolchain through the toolchain manager. However when I import a project using this toolchain I get the nullgcc error.
I also tried creating a new project and setting the toolchain to 10.3-2021.10 but still get the same error.

When I look into the eclipse plugins folder searching for the toolchain binaries, I only see a .jar file but not the actual compiler folder with the binaries
 

ls -l /Applications/STM32CubeIDE.app/Contents/Eclipse/plugins/ | grep gnu-tools-for-stm32

Hello ​@jesusmtz,

Thank you for sharing this request. I have already reported it to our development team for investigation under this internal ticket number CDM0064534.

In the meantime, have you tried to you to use Intel environnement with Rosetta? 

Regards,

Aimen

Hi Aimen,

Thanks for the reply.
Yes, I am currently using STM32 Cube IDE 1.19.0, however I am trying to upgrade to 2.2.0 since Apple has announced is ending the support for Rosetta, and I get I notification to update stm32cubeide. 

So it would be really helpful if I can fully migrate to the apple silicon version :) 

I have not the Intel 2.2.0 version


Regards,
Jesus Martinez
