Hello, i am trying to get one simple project in FreeRTOS with a dsP30f4013 and when i build it i get this Output:

HOW CAN I GET THESE ERRORS GONE? THANK you very much

If you have configUSE_IDLE_HOOK set to 1 in FreeRTOSConfig.h then you must provide an application callback function called vApplicationIdleHook(). Either provide the implementation of the function or set configUSE_IDLE_HOOK to 0:

undefined reference to vPortYield’

vPortYield is defined in portasm_DSPic.S, which you are building, but your device is not a dsPIC device so the preprocessor directives prevent the function outputting any code. You should be building portasm_PIC24.S instead.

Regards.

Sorry - my mistake - ignore that last comment, rereading your post I see you are indeed using a dsPIC.

In which case the most likely cause is that the pre-processor is preventing the vPortYield() function from being included.

Does your project define one of the following:


#if defined( __dsPIC30F__ ) || defined( __dsPIC33F__ )

Regards.

Hello i fixed the problem with vApplicationIdleHook(). Thanks.

Now i need to know where should this line go, in wich file?:

#if defined( __dsPIC30F__ ) || defined( __dsPIC33F__ )

here it is at port.c

 #endif /* __HAS_EDS__ */
 #endif /* MPLAB_PIC24_PORT */

 #if defined( __dsPIC30F__ ) || defined( __dsPIC33F__ )

 #define portRESTORE_CONTEXT()

So, what should i do regarding vPortYield issue? thanks in advance

You don’t need to add that line anywhere, it is already in portASM_pic24.S file, therefore if neither dsPIC30F or dsPIC33F is defined then vPortYield() will be excluded from the build, and I suspect this is what your problem is.

Those definitions come from the Microchip provided architecture header files, you should not need to defined them manually as setting the correct compiler options will result in the correct header files being included, which in turn will result in the correct chip specific pre-processor macros being defined.

Regards.

ok, i understand but im using a dspic30f4013 and i still getting build failed. as shown in the original post:

building the original demo in a diferent directory also give me the same errors, and i also opened the portasm_dsPIC.s file and its empty wich is very rare, in teh original demo when builded correctly i found assembler inside the .s file.

new edit: i just went to the original .s file , opened and copied then pasted into my .s file inside y project folder and it just builded correctly. can anyone understand what happened? why the filed was includes blank?

do you set dsP30f4013 as device in MPLABX project options
