With no loop the task continues executing code and jumps the stack space ... WebFeb 19, 2024 · FreeRTOS creates one IDLE task per core. It also sets watchdog timers on these Tasks. This means if these tasks get starved of execution time, then after a timeout period, the watchdog gets triggered and resets the chip. The IDLE tasks do some important FreeRTOS "household" work in the background, so you have to give them time.
