FreeRTOS on tower MCF51CN with GCC problemPosted by Eugene Leigh on February 24, 2010 Hi All 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. Any ideas? Thanks Eugene
