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

You mean protecting sections of data - not code !
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.
