Sam7 IAR Blocking VTaskDelay()

Posted by Nobody/Anonymous on November 21, 2005
Hi,

i'am programing an application with Arm Sam7 and Wiznet W3100A (IAR 4.30A). The main function creates one task with priority = 1. This task does some tests and creates 2 further tasks after the tests.
During the checks the software stopps sometimes.
The reason is one vTaskDelay() call which don't finished. This happens with argument 1 or 2. Other values will be tested tomorrow.
Does anybody has an idea ? FreeRtos 3.2.2.

Thanks and Regards

Rainer Berns

Do you mean something happens during the function call - or that the task remains delayed even after the timout has expired?

Try increasing the stack sizes of the effected tasks as a first effort.

The task remains delayed.
I have increased the stack sizes and the problem seems to be fixed. Thanks for the hint.

Hi,

I've got almost the same problem. When I call vTaskDelay() function it causes reset of the system but the size of the stacks doesn't have any influence on this. Does anyone have any clue about this issue?

Thanks Alex.
