I'm adding FreeRTOS to my device, but I'm stuck on task priorities.

So guys I'm adding FreeRTOS to my device, but I'm stuck on task priorities. Even though I've checked everything I could check, higher-priority tasks aren't interrupting lower ones , preempting as it's called. Any ideas on what might be causing this?

Solution

Sounds like you might be dealing with a priority inversion, which can happen when the lower priority tasks continues because of a mutex or semaphore
