Hi everyone,

I'm working on an STM32H7RS project (NUCLEO-H7S3L8) with the following setup:

  • Bootloader in internal flash (0x08000000)

  • Application in external OSPI flash (XIP) at 0x70000000

  • Using FreeRTOS

  • Using TIM6 as the HAL time base (not SysTick)

  • Configured using latest STM32CubeMX and STM32CubeIDE (v1.18.1)

My current issue is that while HAL_Delay and TIM6 is working, SysTick seems not to work inside of the RTOS as soon as the scheduler starts.

I noticed that because ther CPU got caught inside osDelay without throwing an error. 

I also already checked the NVIC, but it seems pretty fine to me. Did i otherwise miss something what i configured wrong inside my IOC file?
