I configured 4 equal Tasks in RTEMS and the table as follows:<br>
<br>
rtems_task_create(<br>
Task_name[ 0 ],<br>
2,<br>
RTEMS_MINIMUM_STACK_SIZE * 2,<br>
RTEMS_PREEMPT | RTEMS_TIMESLICE | RTEMS_ASR | RTEMS_INTERRUPT_LEVEL(0),<br>
RTEMS_GLOBAL,<br>
&Task_id[ 0 ]<br>
);<br>
<br>
They will operate in round-robin.<br>
<br>
#define CONFIGURE_MICROSECONDS_PER_<u></u>TICK 10000<br>
#define CONFIGURE_TICKS_PER_TIME_SLICE 50<br>
<br>
The result should show a timeslice of 500 milisseconds, but what i see<br>
in osciloscope is more then 500ms, exactly 834ms. This code is running<br>
in a ERC32 development kit from Atmel.<br>
<br>
Any ideas what is missing for this extra time?<br>

Did you check the timer is operating at the correct frequency ?<span class="HOEnZb"><font color="#888888"><br>
