Are there any restrictions in using vTaskDelay nested im oder functions?


vTaskDelay in function1() works fine, but in function2() it results in data_abort_handler. I'm using Philips LPC2138 with FreeRTOS V3.2.0.

Does anyone have an idea? Thank for help.
Kind regards

There is no problem with using the function in this way. If there is a problem with the call at the higher nesting depth then the most likely problem would be a stack shortage - as the function depth will be using more stack before the call toe vTaskDelay. Try increasing the stack allocated to the task when the task is created.

You're absolutly right. It was a Problem wit to less stack. Thanks a lot!

Kind regards Stefan
