Hi, My target is an ATMega323 and I am working on a simple example where I set/clear bits on PORTA from within a spawned task just to verify the task is running.  The xTaskCreate call appears to work based on the return value, but PORTA does not get updated.  If I move the PORTA manipulation outside of the task, it works fine.  Do I need to do something specific to enable port manipulation from within a task? Thanks,    Robert

Have you started the scheduler vTaskStartScheduler after creation of tasks? 

What a rookie mistake.  Started the scheduler and everything began working.  Thanks.
