Hi all,
I'm testing Xenomai on an apf28 board, with imx28 processor.
I'm using a 3.8.13 kernel with the last Xenomai-head repositorie.
When I use the kernel without xenomai, my GPIO irq works well. But when I patch my kernel with adeos and Xenomai, my gpio IRQ doesn't work!
I have the same problem with the kernel 3.4.6.
I test the gpio IRQ in user space and with RTDM driver.
Do I forget anything?
Cordialement,

The irq line probably needs to be enabled, you should use
rtdm_irq_enable after rtdm_irq_request, if that does not work, try to
request irq at Linux level, then please report your findings to the
mailing list.

Hello Gilles,
I try with the function rtdm_irq_enable after rtdm_irq_request. It doesn't work again.
I request the irq at linux level (see main.c), but with the adeos path, it doesn't work. I don't know why!
Regards,
Antoine MOREL

Could you be more precise? Do you mean you do not receive Linux
interrupts when Adeos is enabled? Or do you try to request an irq with
rtdm_irq_request and do not receive interrupt? Did you configure the irq
type (edge, level).
Regards.

I try the same software (file main.c) with and without adeos.
It works without adeos, and it doesn't work with adeos!
Did I forget anything to do with adeos?
The same software can run well with and without adeos?
Thanks.
Antoine

Hello Gilles,
I tried the patch and it works!
Did the adeos patch will be updated?
Thanks.
Antoine.

Hello Gilles,
You updated the adeos patch but you forgot to include the <linux/ipipe.h> in the gpio-mxs.c
