FreeRtos not running on PIC32MZ

[maharvey (Marc-Andre Harvey)]

I think that you are running in the same issue as me:

configLIST_VOLATILE required - Missing configASSERT in listREMOVE_ITEM

Using the provided sample code for the PIC32 platform and FreeRTOS v202112.00. I ran into an issue in tasks.c when enabling the compiler optimizations (XC32 v4.00 compiler, -O2 optimization). The exception happens in xTaskResumeAll() when the listREMOVE_ITEM macro tries to remove an item with a null pointer as the container. The macro creates a pointer pxList and de-references it without checking if it is NULL, causing an exception. In my case, it seemed to be caused by an aggressive compiler …

I recommend that you add #define configLIST_VOLATILE volatile in FreeRTOSConfig.h to err on the safe side, I would randomly get null-pointer de-referenced without it.
