STM32H7 with LL HAL freeRTOS not running

[hs2 (Hartmut Schaefer)]

In fact the FreeRTOS related interrupts have intentionally the lowest prio.

What is config KERNEL INTERRUPT PRIORITY?

Which port are you using? My answers assume a Cortex-M, but the answers will be different if that is not the case. Where did this text come from as I think it is subtly wrong for the general case, which may be because it is out of date or it may be because you are not using a Cortex-M but something like a PIC24. In the Cortex-M case interrupts that cause a context switch have to run at or below configMAX_SYSCALL_INTERRUPT priority, nothing to do with configKERNEL_INTERRUPT_PRIORITY. Tasks …

I’m not sure but I think you should comment only xPortSysTickHandlerbecause of using TIM7 but not all other FreeRTOS handlers.
