GPIO Interrupt Does Not Work (Killed)

eyyup

I installed Up Board kernel following the document (https://wiki.up-community.org/Ubuntu#Install_Ubuntu_kernel_4.15.0_for_UP_from_PPA).

I used GPIO as output to Led on and off without any problem. But when i configured GPIO pin (edge file) as "rising" or "falling", the process killed and OS freezes.

Same problem here, but I used the libgpiod to setup the interrupt. I opened a terminal with ctrl+alt+f6 and ran my program, it said BUG: unable to handle kernel NULL pointer deference, then kernel panic.

We are looking into it and provide you feedback as soon as possible.

Thanks for reporting it.

Any update on this?

New linux kernel 5.0.0 solves this.
