Hello, I start using Free RTOS on H755ZI dual core, I only use RTOS on core M7, core M4 do nothing and I received a notice from CubeMX:

"CubeMX strongly suggests to use a time-base source other than SysTick when FreeRTOS is used."

But I can not change Systick to other timer be like the image above. What setting step did I miss?

Hello,

FreeRTOS needs Systick for its time base scheduler while HAL needs another timer like TIM6 or TIM7 for its time base.

You need to enable TIM6 or TIM7 in "Timers" section before to switch the system base timer for M7 from systick to TIMx:
