I'm trying to use FreeRTOS with GCC 4.4.1 from CodeSourcery for Coldfire mcf51cn.
I have compiled FreeRTOS CodeWarrior demo for MCF51CN128 with GCC. Adapted makefile from MCF52233 demo and trying to run an LED task.
It look like I have a problem with context switching. Inserting breakpoints into vPortYieldISR and stepping it look like it crashes after switching back to LED task: - vPortStartFirstTask: (LED) - vPortYieldISR: (IDLE) - vPortYieldISR: stores context of current task, restores context of LED task (doesn't look like a garbage or pointing out of stack) __cs3_interrupt_vector_coldfire()
Compiler options are the same as for MCF52233 apart from cpuid and liker script.
