This means that it is definitely related to your heap/task size. I think you should debug more into that direction into understanding your new task stack requirements.

UPdate : i canged the heap_1.c to heap_2.c that has a better ram managment from my understading and it works.

The only issue is that when i'm connected the Log thread don't work anymore and i have no log printing.

Hello, i've tried but the issue is still the same even if i allocate mush more stack

#define configTOTAL_HEAP_SIZE                                                     ( 16384 )

i tried also with 8192 but the issue is still the same

I think the hrs_freertos example is using up all the free stack that is allocated in the FreeRTOSConfig.h file.

You need to increase the maximum heap size configTOTAL_HEAP_SIZE so that there is enough stack from the new task you created. All the hardfaults and unpredictable behavior you are seeing could be a side affect from the stack overflow. Give enough stack to you task and most likely this issue will go away.
