Hi all,

I´ve compilled FreeRTOS version 5.0.2 with IAR Workbench, following the same example for LPC2000 port, all works fine with the flash led example but when I add more code files to the project, even without using their functions, the program doesn’t run anymore… I’ve noticed that when I add more heap to configTOTAL\_HEAP\_SIZE in FreeRTOSConfig.h, even using less than memory limit, everything stops working too.

Could you give any possible solution to this issue?

Thank you.

Did you remember to change linker script from that used to base your port to be correct for LPC2294?

Does the call to vTaskStartScheduler() return.&nbsp; If it does you are out of heap.

Yes, I’ve changed the script for memory boundaries of Phytec PCM-023 board, using the workbench edit script tool, and the vTaskStartScheduler() doesn’t return,&nbsp; the board led stops flashing… it seems that it’s branching to a wrong address…

When I change configTOTAL\_HEAP\_SIZE&nbsp; to 14196 or to 14204 it stops working, and when I change its value to 14200 works fine!!! Very strange!!!
