Hello everyone, here is some new clues:
1. I tried xenomai 3.0.8, kernel 3.14.17 and ipipe-core-4.14.71-arm-4.patch.
Still the same question.
2. It seems the system is locked up once a gpio interrupt is triggered.
3. Some debug information show that, once a gpio interrupt is triggered, the
function
'omap_gpio_irq_handler' is triggered all the time.
There may be a little bug exists, but i don't know how to amend it. Thank you
very much, if anyone can help.
