RE: [microblaze-uclinux] uclinux port to Multimedia board

Hi Didier,

You can look at the interrupt controller status register and verify that
when the timer calls an interrupt, this interrupt is passed through the
interrupt controller to the microblaze.  The files microblaze_intc.c and
microblaze_intc.h give some examples on how to access the interrupt
controller.

Also, make sure you aren't overwriting the interrupt vector table (which is
located somewhere between 0x00000000 and 0x00003FFF.  Hint: If you are
loading xmbstub onto the microblaze, then you are overwriting the interrupt
vector! :)

Chris
