Dear Sir/Madam, I am trying to adapt the pic24 FreeRTOS demo to another project (still based on the pic24) I have been able to remove all the demo code successfully except for the crflash.c coroutines. If i comment out the call to vStartFlashCoRoutines( mainNUMFLASHCOROUTINES ) in main i get the following run time error: Target halted due to Software Breakpoint in user code I have tried removing the crflash.c code and setting configUSECOROUTINES to 0 etc…but i then get lots of compile/link errors. My question is what steps do i need to follow in order to completely remove crflash from the project? Thank you so much Best wishes

but i then get lots of compile/link errors

Can only guess unless you post the errors.

Hi Dave With configUSECOROUTINES set to 0 in FreeRTOSConfig.h, i get the following errors: make[1]: Leaving directory ‘C:/Para/MicroChip/Explorer16/FreeRTOSExplorer16/FreeRTOS/Demo/PIC24MPLAB/RTOSExplorer16PIC24.X’ nbproject/Makefile-impl.mk:39: recipe for target ‘.build-impl’ failed build/default/production/ext/1472/main.o(.text+0xe6): In function _vApplicationIdleHook': : undefined reference tovCoRoutineSchedule’ build/default/production/ext/1472/main.o(.text+0xe8): In function _vApplicationIdleHook': : undefined reference tovCoRoutineSchedule’ build/default/production/ext/1163846883/crflash.o(.text+0x1e): In function .L3': : undefined reference toxQueueCRReceive’ build/default/production/ext/1163846883/crflash.o(.text+0x20): In function .L3': : undefined reference toxQueueCRReceive’ build/default/production/ext/1163846883/crflash.o(.text+0x32): In function .L4': : undefined reference toxQueueCRReceive’ build/default/production/ext/1163846883/crflash.o(.text+0x34): In function .L4': : undefined reference toxQueueCRReceive’ build/default/production/ext/1163846883/crflash.o(.text+0x7a): In function .L10': : undefined reference toxQueueCRSend’ build/default/production/ext/1163846883/crflash.o(.text+0x7c): In function .L10': : undefined reference toxQueueCRSend’ build/default/production/ext/1163846883/crflash.o(.text+0x8e): In function .L11': : undefined reference toxQueueCRSend’ build/default/production/ext/1163846883/crflash.o(.text+0x90): In function .L11': : undefined reference toxQueueCRSend’ build/default/production/ext/1163846883/crflash.o(.text+0xb2): In function .L15': : undefined reference tovCoRoutineAddToDelayedList’ build/default/production/ext/1163846883/crflash.o(.text+0xb4): In function .L15': : undefined reference tovCoRoutineAddToDelayedList’ build/default/production/ext/1163846883/crflash.o(.text+0xec): In function .L22': : undefined reference toxCoRoutineCreate’ build/default/production/ext/1163846883/crflash.o(.text+0xee): In function .L22': : undefined reference toxCoRoutineCreate’ build/default/production/ext/1163846883/crflash.o(.text+0xfc): In function .L21': : undefined reference toxCoRoutineCreate’ build/default/production/ext/1163846883/crflash.o(.text+0xfe): In function .L21': : undefined reference toxCoRoutineCreate’ make[2]: *** [dist/default/production/RTOSExplorer16PIC24.X.production.hex] Error 255 make[1]: *** [.build-conf] Error 2 make: *** [.build-impl] Error 2 BUILD FAILED (exit value 2, total time: 4s) Thanks

build/default/production/ext/1472/main.o(.text+0xe6): In function _vApplicationIdleHook’: : undefined reference tovCoRoutineSchedule’

This error tells you vCoRoutineSchedule() is called in the idle hook. As you set configUSECOROUTINES to 0 coroutine code will not be built so vCoRoutineSchedule() is undefined. Just remove the call and the error will be fixed.

build/default/production/_ext/1163846883/crflash.o

Same thing. If configUSECOROUTINES is 0 you cant build files that use coroutines, so dont build crflash.c.

sorry, my mistake, i did comment out the vCoRoutineSchedule() earlier, so that error goes away…when you say don’t build crflash.c… is it just the case of removing the file from the project?…or do i have to modify the makefile or something?

Hi Dave Ok, ive taken out the crflash file from the project, was getting some other errors after that, so did a clean build and all fine now! Thanks for all your help…much appreciated.
