Hi all,
I’m using Cortex M33 and CMSIS FreeRTOS 10.5.1. In my project, I have total 5 tasks.
Idle: Priority 0,
App_CyclicTask: xTaskCreateStatic (Priority 1, puxStackBuffer: 600)
App_EventTask: xTaskCreateStatic (Priority 3, puxStackBuffer: 500)
App_CriticalTask: xTaskCreateStatic (Priority 5, puxStackBuffer: 500)
TmrTask: Priority 6
At first, it seems to work ok but after amount of time, I see tickcount does not increase and task is not switching anymore, I assume that OS is hanging (no hardfault, it just hang there)
So, if anyone has experienced with this issue or if you need more info, please let know!
Here is the FreeRTOSConfig
