Thanks for the help, it was a not properly setup TLB.
New problem:
The code start running ( 2 threads each has a counter in a loop with a
delay) the counters get to 1
and then it sits in the idle loop.
There are no interupts occuring.
I manualy enabled the decrementer interupt and then both the counters got to
2 and stopped.
which interupt does the scheduler use ?
where in the code does it init the interupts to be used by the scheduler /
task switching?
thanks in advance.
Ilya
