I am trying to use freetos on mega128. But the application is not working as it should. I have declared two tasks while toggle buzzer and led at an interval of 1 sec. But only led are toggling ( only the task declared in last works). If I use vTaskDelay or vTaskDelayUntil then the system hangs.
Changes I have made :-
1) In make file change from mega323 to mega128
Mega128 is running on 8MHz internal RC osc.

I would say it sounds like the tick interrupt was not firing, but you say the LED toggle is working? Is the period of the LED toggle correct?
Does a 128 and 323 have the same timers?

What can be the case that vTaskDelay or vTaskDelayUntil causes system to hang.
