Hello we would like to use FreeRtos on a M33 (STM32L5). For our projects we would like to use the following settings for the priorities: NVIC_SetPriorityGrouping(4); → 8 Groups with 32 Subpriorities bxxx.yyyy Our idea is that the groups should serve the following purpose: 0 Not used because not…

Setting all the priority bits to preempt priority makes the configuration much simpler and therefore, is still recommended for v8M ports. Consider the following example where 3 priority bits are implemented and priority group is set to 5: 000 | Priority Level 0, Sub priority Level 0 001 | Priority…

I’d like to add this pretty good explanation of FreeRTOS interrupt mapping and configuration.
