[FreeRTOS Home] [Live FreeRTOS Forum] [FAQ] [Archive Top] [April 2005 Threads] 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.
RE: Heap size problem in PIC18F8720 Posted by Richard on April 6, 2005 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: https://sourceforge.net/forum/forum.php?thread_id=1255600&forum_id=382005
which notes a get around for variables that straddle the block boundaries.
