Dear all,
I am trying to attach my interrupt handler to any of irq1-7. but i am
unsuccessful in doing that. My cpu board is having mcf5475 processor and
is running on uclinux , linux kernel-2.4.x. I also tried to attach my
code to the already connected isr. but i was unable to find where
exactly in the directory structure are the interrupt handlers located.
Can anyone plz tell me how to go about these 2 issues.
Is it that when these pins are configured in GPIO mode then interrupt
handlers are not called? but i can notice the output on my hyper
terminal when ever i ground the irq7 pins on my board. the o/p is like
this -
"GPIO value = 7
status = FFFF"
When i ground irq6 pins on my board, then o/p is very similar -
"GPIO value = 6
status = FFFF"
What exactly is happening, if these pins are configured in GPIO mode by
uclinux, then where from these o/p is coming. Which handler is giving that?
Or, the situation is entirely different than whatever i am thinking.?
Please help me out guys.........!
Regards and thanx.
Rahul.
