Compile and perform unit test for STM32 on Host

Postby dpa » Tue May 07, 2019 11:18 am


According to, it is possible to compile code meant for STM32 target for x86 host. My main goal is to unit test my code on Host (PC x86) before deploying on target (STM32)
But by compiling my code with toolchain PC Tools, I got these errors:

To unit test on a different platform, you need to stub out all platform specific code, especially anything that uses assembly since you are using very different CPUs.
