Hi,
I am trying to port a library that is working with FreeRTOS to RTX. The microcontroller is the same: STM32F4. The library uses critical sections. I have tried using the same implementation for the critical section for RTX as for FreeRTOS(BASEPRI) but I often end up in UsageFault. I know that RTX uses extensively the SVC in the code.
Could it be that the Critical sections should be implemented differently ? Do you know of any other differences between FreeRTOS and RTX that could cause problems?
Best regards, Sebastian
Yes, poor choice of word...I meant protecting data. Any opinion on why and when to use SVCs instead of s/w (PRIMASK) for Cortex-M0.
