RTOS KEIL to GCC conversion

Question

I have a FreeRTOS code under KEIL compiler and all is OK. When I convert the same code to CooCox under GCC, where are only changes in asm code in port.c etc. It does not work. It is looping in debug in function xPortStartScheduler() where prvPortStartFirstTask() go to Svc_Handler and again to xPortStartScheduler() etc. I think that problem can be somewhere in vectors or startup file.

In CooCox I can't find heap and stack initialization instead of Keil sturtup.

Someone has an idea?

Answer 1

I'm new to freeRTOS but you may find the startup file in CooCox by adding CMSIS boot component to the project. View->Repository and add CMSIS boot component to visualize the startup file in cmsis_boot/startup directory.

Answer 2

Problem was solved by rewriting vector table of imported CooCox sturtup where "vPortSVCHandler" was not defined. – Hw-dev Cz
