Subject: [Xenomai-help] Having trouble with a BeagleBoard GPIO interrupt pin

I am converting my second driver to RTDM. This one receives a negativing going edge triggered interrupt on GPIO133 of the OMAP3 chip.

I have...
ret = rtdm_irq_request(&adis_data_rdy_irq_handle, irq,
                   adis_data_rdy_irq_handler,
                   RTDM_IRQTYPE_EDGE, 
                   "asuspidvr", ctx);
then...
ret = rtdm_irq_enable(&adis_data_rdy_irq_handle);

but the interrupt handler is never invoked.

cat /proc/xenomai/irq shows:
IRQ         CPU0
 37:       15815         [timer]
 39:           0         asuspidvr
 48:           0         asuspidvr
 91:           0         asuspidvr
293:           0         asuspidvr
418:           0         [virtual]

IRQ 293 in the interrupt that should be happening.

I can see the pulses on the input pin and the non-rt version of the driver sees the interrupts, so that excludes hardware issues and u-boot pin configuration issues.

Any suggestions?
Regards,
Bob Feretich
