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:

Thanks

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.
