Re: [Xenomai-help] PIOX irq problems with at91sam9260

[Juan Antonio Garcia Redondo <juan-antonio.garcia@domain.hid>]

I've found a workaround for my problem, but I'm not sure if is the
correct solution.

First, my test program test_irq.c had an error, after request the irq,
it have be enabled; anyway the problem persists because the
__ipipe_mach_demux_irq find the irq disabled (gpio->depth = 1).

My workaround:
