STM32H563: Not able to set NVIC priorities properly for HDMA & SPI

PFlor.2 · ‎2024-11-26

See attached .ioc

Tried to change LIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY from 5 to 1 in the FreeRTOS settings, but didn't seem to allow me to lower the priority levels in NVIC settings.

Hello @PFlor.2

First let me thank you for posting.

Could you provide more details about which priority level you are not able to modify.
Share screenshots if possible.

Pretty much any of the peripheral priority levels in the NVIC settings except the TimeBase which is using Timer6, it is set to priority 0 but all others cannot be set lower than 5 in .ioc NVIC settings. Thought maybe it had something to do with using FreeRTOS.
