Is freertos Preemtion for touchgfx?

[Epamuk]

Hi,

I have a project for STM32L4R9AI and I have analog and digital clock screens. When I set configUSE_PREEMPTION to 0 my code is stuck. Some tasks are working but my_clock_task and model tick doesnt work.

If I set configUSE_PREEMPTION to 1 , everything is ok.

I want to work without preemtion . Is it a compulsory situation to make configUSE_PREEMPTION=1 for touchgfx?
