hello all,

what can be the reason for FreeRtos to start running before I call vTaskStartScheduler();

I know for sure that its really running because the created tasks are actives.

thanks in advance

Avi

Is an interrupt that performs a context switch executing before you start the scheduler? Normally that would cause crash but I cannot think of any other possible causes.
