XU4 cloudshell with 4.9 and IR-remote

Troubleshooting
1

After upgrading to 4.9 kernel the IR-remote didn’t work anymore. I had to rerun the ./install_ir.sh script to fix the problem.

2

Thanks for the heads up, i’ll link this to the ticket so we can investigate:
https://github.com/Fourdee/DietPi/issues/926

I’ve just run this script for the first time and the IR doesn’t alter the Cloudshell display.

Doing

cat /dev/lirc0

from the command line then pressing the buttons produces characters on the screen so the IR is working.

Also the Cloudshell display does not auto power off - the screen goes dark but the light is still on on the periphery. New with kernel 4.9.

If you apply the settings with dietpi-cloudshell it goes off fully.

John,

I use the original hardkernel remote, I can not switch off the cloudshell script, I just turn off the backlight. You can find my setup in one of my old posts :

hope this helps you.

Hi Patrick,

Thanks I installed wiring pi from the menu and used your config but it doesn’t work. I’ve the hardkernel remote and

cat /dev/lirc0

shows characters onscreen but when I stop the lirc service It still shows these characters - not sure what’s going on here.

John,

Did you install irexec?
cat /dev/lirc0 gives as output : cat: /dev/lirc0: Device or resource busy

No - tried the obvious apt-get install irexec -

But unable to locate package. How do you do it?

John,

I think irexec is part of the lirc package, I installed it a year ago before it was in dietpi-software. I posted then how it installed it (see this post)
https://dietpi.com/forum/t/installing-lirc-on-odroid-xu4-cloudshell/515/1

I hope you can solve it.

Hi Patrick,

Thanks for your help but no luck here. Would you mind posting the contents of /etc/lirc hardware.conf, lircd.conf and lircm.conf?

I hope this can help you. I don’t have X.org installed, I always ssh to the XU4

Thanks Patrick but this one has me stumped. I have the same setup as you, have copied your config files but it doesn’t work.

I’ll keep at it.
