i m getting this error when i m going to build the project. Error – section ‘.udata_portheap.o’ can not fit the section. Section ‘.udata_portheap.o’ length=0x00000476. please tell what i am missing… regards

Have you changed the linker script?  The one in the FreeRTOS.org download creates one large block into which the heap can fit.  If you are using the linker script from your MPLAB distribution then you will get this error. Regards.

Is there a BKM to manipulate the lkr file provided with MCC18 to work with FreeRtos? I´m trying to use a PIC18F4620 with a DEMO and I need the associated lkr file or some knowledge to correctly modify the one provided in the MCC18 distribution. Regards.

I modified the original from Microchip for pic18F4620 to allow the heap to fit. Here it is: // $Id: 18f4620.lkr,v 1.3 2008/05/20 19:32:00 Lorenzati Exp $ // File: 18f4620.lkr // Sample linker script for the PIC18F4620 processor LIBPATH .
