Heap size problem in PIC18F8720
Posted by Nobody/Anonymous on April 6, 2005
I have a heap_size problem compilating freertos for the pic18f8720. The C compiler shows the warning message 'cannot fit the section'. The only solution that I found was to fit the heap_size at 251 bytes!
The pic18f8720 has 4kbytes of RAM.

You need to modify the linker script to create a block large enough to hold the heap.
Take a look at the linker script 18f452.lkr found in the demo/PIC directory of the download. The block named BIG_BLOCK is where the heap goes.
Also take a look at the thread:
which notes a get around for variables that straddle the block boundaries.
