In this tutorial, we look at how memory is managed in an RTOS (specifically, FreeRTOS).

How to configure tasks in FreeRTOS to share a global variable and execute concurrently with the same prioritization level.

Priority inversion occurs when a high priority task yields to a low priority task because the low priority task holds a lock, such as a mutex or semaphore, needed by the high priority task.
