[microblaze-uclinux] Interrupt issue
I'm using the latest Petalinux release and kernel 2.4
I'm trying to test GPIO interrupt, but have failed so far.
There's no response at all when I loaded keypaddev.o come with the package.
I wrote a simple driver, loaded it, I was able to see it successfully hooked
to interrupt IRQ4 I wanted.
This interrupt is associated with Press Button on Spartan 3E-1600 eva board.
But there's no response when I pressed the buttons.
I'm sure the board works fine with interrupt button as I tested with Windows
EDK code in standalone mode, ie no OS at all.
Compare all relevant regosters in these 2 cases, all ENABLE regsiters are
the same. T the only differences are the STATUS ones because there's no
response to IRQ using Petalinux, but responding from standalone one.
I'd really appreciate your help
