Hello,
I had no problem in using request_irq() for MPC8272 with arch=ppc from
Montavista Linux
But I have failure for MPC8313 with arch=powerpc from FreeScale LTIB Linux with
error code -38
I found its header file mpc83xx.h under include/asm-ppc, while it's supposed to
be under include/asm-powerpc.
I did try to copy the header file to directory asm-powerpc
>From MPC8313 datasheet, I have
GPIO_IRQ = 74
and I use
DEVICE_NAME = "ppc"
IRQ_FLAG = IRQF_SHARED // use new flag
here my function call
request_irq (GPIO_IRQ,
ppc_ISR,
IRQ_FLAG,
DEVICE_NAME,
NULL);
I'd appreciate any help on this problem.
Best Regards,
Duy-Kyng
