Power Button ODROID N2+ CoreELEC 19.5-Matrix

[Kamui]

hey guys, trying to get the Power Button on my ODROID N2+ with CoreELEC 19.5-Matrix to work.

i wired the button to pin 11 & 9, checked that 3 times already
edited the config.ini, saved and rebooted.

first edit was only this three lines

### in case of GPIOX.3 (Pin 11) of 2x20 pins connector
setenv gpiopower "479"
setenv bootargs ${bootargs} gpiopower=${gpiopower}

second edit this line (from the odroid wiki)
setenv bootargs "root=UUID=e139ce78-9841-40fe-8823-96a304a09859 rootwait rw ${condev} ${amlogic} no_console_suspend fsck.repair=yes net.ifnames=0 elevator=noop hdmimode=${hdmimode} cvbsmode=576cvbs max_freq_a53=${max_freq_a53} max_freq_a73=${max_freq_a73} maxcpus=${maxcpus} voutmode=${voutmode} ${cmode} disablehpd=${disablehpd} cvbscable=${cvbscable} overscan=${overscan} ${hid_quirks} monitor_onoff=${monitor_onoff} logo=osd0,loaded ${cec_enable}"

but nothing happens when i press the button

any idead what i did wrong?
(tried googling /searching, found nothing to help me)

Only edit this line:

CoreELEC/CoreELEC/blob/coreelec-20/projects/Amlogic-ce/devices/Amlogic-ng/bootloader/config.ini#L87

You will need to find the correct gpio number for your pin.
I don’t find the description anymore but it’s somewhere here how to identify the correct gpio number.
