IRQ handling on ARM processor (StrongARM)

Discussion in 'Embedded' started by pierre_de_caen, May 8, 2006.

  1. Hi, I try to handle some interrupts on my Yopy (Strongarm processor),
    in particular keyboard interrupts.
    So, IRQ vector table is at 0x00000018 but I can't write any value at
    these address in monitor mode (i.e. without linux, without any OS).

    I have written my IRQ handler but I can't tell the machine to start my
    handler when an IRQ occurs.

    Do you know what I should do before writing my IRQ handler's address at
    IRQ vector address or if there is another method to tell that this
    handler should intercept IRQs. I program in C but I can add ASM if it's
    needed.

    Thanks for your help,

    Pierre
