InstrFetchProhibited at cpu_start: Pro cpu start user code
Posted: Fri Jul 05, 2024 10:05 am
Hello,
we have a bigger project where a lot of code was added in a separate branch. This branch works fine until its merged into the main branch. The code does not have any obvious flaws, which could explain the error below.
I am a bit confused what needs to happen, that a crash triggers directly where cpu_start: Pro cpu start user code should be printed. Maybe somebody can help me there. Thanks.
