- Subject: [ECOS] interrupts and scheduling
Hello,
We have two interrupts one at every .5msecs(INT1) and
other every 1 msec(INT2).
In our application we have two threads. When INT1 is
enabled/handled the scheduler is not able to schedule
the threads.
Where as when only INT2 is enabled both the threads
get scheduled.
We have tried this using mlq and bit-map. But found
threads scheduling not working when INT1 is enabled.
The INT1 ISR routine execution time taken is 1.3
micro-secs.
The processor ( sparc) runs at 32-MHz.
What could be the possible issue?. How do we go about
debugging the same?.
-Thanks for your time.
