Thank you for your help Greg & Philippe! I merged gpio-omap.c from 4.14 kernel to my 4.11 kernel, result is freezed cpu after interrupt. Then, I compiled 4.14 latest ipipe-arm kernel from git (nothing added, nothing removed), and similar thing happens. Only I could see some time after, until

Re: [Xenomai] interrupt on edge problem, unexpected IRQ trap

As Philippe mentioned, they are some missing pieces that need to be added to the ipipe. The link Philippe provided will give you guidance on how to make those changes to your custom kernel. The other option is you could use the ipipe-arm tree and the mainline kernel. Also, unrelated, the gpios

Re: [Xenomai] interrupt on edge problem, unexpected IRQ trap

Xenomai 3.0.6, and ipipe-core-4.9.51-arm-3, patched on sunxi 4.11.2 kernel (with BeagleBone patches applied too). Same situation with this kernel -> https://github.com/beagleboard/linux/tree/4.9-xenomai Just as Giulio wrote, GPIO is configured with: echo 60 > /sys/class/gpio/export echo both >

Re: [Xenomai] interrupt on edge problem, unexpected IRQ trap

Can you provide what version of Xenomai you are using and what ipipe patch you are using? It also may be helpful if you could provide some sort of sample code that reproduces the problem. -Greg On Mon, Feb 26, 2018 at 8:46 AM, wrote: > Hello, > > I have

[Xenomai] interrupt on edge problem, unexpected IRQ trap

Hello, I have a problem with new I-pipe patch, which was not existing with legacy patch on 3.14 kernel, on BeagleBone platform. When GPIO pin is configured as input with edge interrupt enable, on IRQ occurrence the following message appears: [ 303.331386] irq 88, desc: dc1be400, depth: 0,
