    By the way… your udemy course “Build Your Own RealTime OS” is a valuable resource for me as I`m writing from the scratch my own Multi-threads full preemptive OS on NXP S32K144. I read “definitive-guide-to-arm-cortex-m3-2nd-edition” and ARM documentation but I still don´t catch how to implement it and use it. I got stuck during context switch while an asynchronous interruption arrives and I guess PendSv can help me to carry out the context switch in this case.
