After a few days of head pounding, I’ve traced a problem: enabling vTaskList with:
~~~
define configUSETRACEFACILITY 1
define configUSESTATSFORMATTING_FUNCTIONS 1
~~~
…causes FreeRTOS to halt at vPortFree().
vTaskList worked fine in 7.0 and 7.3, and did not require setting these constants.
I have not touched the memory management scheme. Looked at which memmang file has been selected and see** heap_1.c**
How to fix?
Here’s the entire config:
