Strange problem with tasks

[master_szumi]

My problem is vey strange.

I started my multi-task application on mqx - and it works fine a while.

After few minutes only one task is active infinitely.

In that task is line: _time_delay(...) so other task shoud be used then.

I look to "Task summary" and "Stack usage" and everything is ok (other tasks are "Ready" and stack is not overflow).

What shoud I check more?

The 1000 value is not the problem (I have used it just fine but it adds a bit more clock overhead).  I would guess that your code has some other loop that is spinning.  I would look carefully at the code to locate it.  If you use the default task scheduling, you will not give up the processor unless a higher priority task is ready to run.  What are the priorities of the task that is ready that is not running?  My guess is they have the same priority.

It seems that scheduler works wrong.

In mqx project i'm using:

#define BSP_ALARM_FREQUENCY      (1000)

It may cause that kind of problem?
