Hi folks,

When trying to compile RTOS for MSP430 gcc I get the following error messages:

FreeRTOS\tasks.o: In function `prvIdleTask’:
…/FreeRTOS/tasks.c:1785: undefined reference to `vApplicationIdleHook’
FreeRTOS\tasks.o: In function `prvAllocateTCBAndStack’:

Build error occurred, build is stopped

I´ve looked for pvPortMalloc, and it is prototyped in portables.h, but there isn´t such a function in port.c (where it should be located, at least in theory) or anywhere else. I´ve not looked for the other functions.
I don´t get what I´m missing here, and I don´t believe it is related to my compiler or IDE (using latest mspgcc within eclipse), since I´ve already compiled good code with it.

Any help will be very welcome.

Hi Andre,
a) Define void vApplicationIdleHook() in your Application to get an idle event from the scheduler. This can also be disabled in the FreeRTOS_Config.h
b) You need to add one of the three heap managers to your project. heap_1…3.c for having memory management. Files are located in FreeRTOS/portable/MemMang
c) For Queue stuff add the queue.h to your include area.

Hope this helps,
Peter

Thanks Peter,

     I´ve added heap_1.c heap manager, and it worked like a charm. No more complains from the compiler.
     I´ve seen there is a documentation on this on the website (after reading your hints), but I think this should be made more clear on the pages, specially on the "Source Organization" page, since it says that the kernel is composed of only 3 files (4 if co-routines are enabled); this should clearly count as a file, since it is needed for a clean compile. What do you think?
     Maybe I should contact Mr. Richard Barry regarding this. Thank you one more time, best regards,

Andre.
