Hello !

Do you have idea why macro portSWITCH_TO_USER_MODE()  is not defined for freertos  ?

Hi, Eugene,

I have searched  "portSWITCH_TO_USER_MODE() " as a key words in google, the api function is related to MPU(memory protection unit), which can limit the resource scope a task can access. I think the freeRtos example does not use the function.
