Hello, it's me again :). After having my board set up and in use as previously described I wanted to have a look at the temperature, but nowhere it is displayed.

Same for me. I tried to move my data to a Usb-SSD but got basically the same result. Black screen and no boot. Im on latest upgrade too: root@OdroidN2:/# uname -a Linux OdroidN2 5.4.28-meson64 #20.02.8 SMP PREEMPT Mon Mar 30 09:12:52 CEST 2020 aarch64 aarch64 aarch64 GNU/Linux

Just noticed that an update for wiringpi was available - thank you - gpio readall is now working as expected as i get the table the link was referring to. Unfortunately the powerbutton is still not working when using the lines given above in boot.ini. I tested the same with a kernel from hardkernel (which i tried because my trial to move the system to ssd failed miserably) and there the button worked as expected. I guess it is still an issue of the kernel?

Thanks for your effort. I fear that i need more detailed instructions. Can you give me the command set i must use or a direction where to look?

Actually i don't want to program with WiringPi, i just want to use the hardwarepins for a hardwarebutton. WiringPi and gpio readall was just a test if basic functionality is present (which is not). But as your EDIT says there might be a different problem than in WiringPi. It does not break Armbian on OdroidN2 for me, but ... i just want to have this shiny button working and not just shining :).

Thank you very much, I used your instructions from over there, and it works (i got warnings but i guess these are ok)! Do I have to issue these commands at every boot, or is it "done" now? I read here that you have to put something in config.txt which might translate to boot.ini? Any chance that i can get the GPIO working in a similar manner?

I'm in the same boat, as it seems. Can you use your GPIO?

Good morning, after some time using armbian on my OdroidN2 with great success (got Nextcloud with working Talk installed, external USB, Minecraft server, nginx, LetsEncrypt, Netdata...) I encountered some problems I am not able to solve by myself: I bought a RTC battery and a LED power button to "finalize" my Odroid (hardwarewise), and to my surprise both did not work as expected. RTC: It says: chris@OdroidN2:~$ sudo hwclock hwclock: select() to /dev/rtc0 to wait for clock tick timed out cat /proc/interrupts |grep rtc ...gives me also no return (empty string), so i guess there is a module missing in the kernel : chris@OdroidN2:~$ uname -a Linux OdroidN2 5.4.28-meson64 #20.02.8 SMP PREEMPT Mon Mar 30 09:12:52 CEST 2020 aarch64 aarch64 aarch64 GNU/Linux There is a post on RTC here in the forums which looks like my problem, its here. Maybe it is the same problem? Next problem is GPIO: As mentioned above i tried to install a LED power button, and used this to set it up. I got the LED working as expected (Pin 1 and 6), but the power on-off is not working (Pin 9 and 11). The button i purchased is a NO-switch, and after checking the correct wiring i also tested the button for funcion. Everything is fine according to the multimeter. After some reading i tested for working GPIO (installed wiringpi with this instruction), and it looks like this is the problem: chris@OdroidN2:~$ sudo gpio readall No "Hardware" linechris@OdroidN2:~$ It looks to me as there is also some module missing or am i wrong? I also have no i2c bus, in /dev/ there is only i2c-0. Now - what is wrong and what can i do about it? Is there information missing i should provide to solve my problem?
