Experiencing problems with freeRTOS tick

Posted by lmp on May 13, 2008
Hi, my work on mips32 porting goes on. Does anybody know which one could be a reason for the FreeRTOS tick not to start? I create all my tasks then start the scheduler. After a bit of time spent on debugging i noticed that the first task starts correctly, but a context switch never happens, event if I call a taskYield() from that task. I also noticed that xTaskGetTickCount() always returns 0.

What should I check? Thanks.

Sounds like you have interrupts disabled. Does the context of the first task that is started have interrupts enabled?
