BUILD FAILED (exit value 2, total time: 7s)

Thank you for reporting this problem. Please try opening FreeRTOS.h, and finding the lines:

#ifndef configUSE_PORT_OPTIMISED_TASK_SELECTION
	#define configUSE_PORT_OPTIMISED_TASK_SELECTION 1
#endif

and change the 1 to a 0.

That fixes the problem for me. The default of one will have to move into individual port layers.

Regards.

okay thanks a lot. actually the problem was that i forgot 1> to include "portasm_dspic.s" in the project sources 2> to implement "vApplicationIdleHook".

i got issues with configUSEPORTOPTIMISEDTASKSELECTION too. i changed it to 0 and got no more errors

i have this warning : ../../../Source/portable/MemMang/heap1.c: In function 'pvPortMalloc': ../../../Source/portable/MemMang/heap1.c:114:39: warning: cast from pointer to integer of different size

should i ignore it ? is it possible to fix it ?

THANKS :) alban

Yes that can be ignored.

Regards.
