Hello

A console image was generated with DEY 3.0 r2 on Nov. 3rd. 2020.

While gpiodetect, gpioinfo, gpioset, gpioread were working properly
gpiomon was not working.

These were my attempts:
root@btc:~# gpiomon 6 4
gpiomon: error waiting for events: No such device
root@btc:~# gpiomon ioexp-gpio 4
gpiomon: error waiting for events: No such device
root@btc:~# gpiomon --num-events 1 --rising-edge ioexp-gpio 4
gpiomon: error waiting for events: No such device
root@btc:~# gpiomon --num-events 1 --rising-edge gpiochip6 4
gpiomon: error waiting for events: No such device
root@btc:~# gpioget ioexp-gpio 4
1
root@btc:~# gpioget ioexp-gpio 4
0
root@btc:~# gpiomon ioexp-gpio 4
gpiomon: error waiting for events: No such device
root@btc:~# gpiomon gpiochip6 4
gpiomon: error waiting for events: No such device
root@btc:~# gpiomon gpiochip5 4
gpiomon: error waiting for events: No such device
root@btc:~# gpiomon gpiochip5 3
gpiomon: error waiting for events: No such device
root@btc:~# gpiomon --format=“%e %o %s %n” --falling-edge gpiochip6 4
gpiomon: error waiting for events: No such device

The pin has to be configured as GPIO for this to work.
on SBC Pro:

On the ConnectCore 6UL SBC Pro GPIO connector:

Pad Signal GPIO
12 EXP_GPIO_2 GPIO1_IO03

root@ccimx6ulsbc:~# gpiomon gpiochip1 3
root@ccimx6ulsbc:~# gpiomon gpiochip4 14
root@ccimx6ulsbc:~# gpiomon gpiochip1 5
And it works for me. Can you please check?
Please note that GPIO mon is only working for pins that are Interrupt (IRQ) capable.
