[SOLVED] Ubuntu 18.04 (v3.0) LIRC HK IR Remote Not Working

noobs4u · Unread post by **noobs4u** » Wed Jul 11, 2018 9:56 am

I installed a fresh copy of Ubuntu 18.04 (v3.0) on my C2 and cannot get the HK IR remote to work. It wont even work with Kodi. Is there an official guide to get the IR Remote setup properly for the Ubuntu 18.04 (v3.0) image on the C2? (It worked flawlessly with the Ubuntu 16.04 (v2.4) image on the same C2).

Code: Select all

odroid@odroid:~$ sudo apt-get install lirc

Refer this LIRC guide for Ubuntu 18.04.

Manually checked it also. there is no lirc0 in the /dev directory

Code: Select all

odroid@odroid:~$ ls /dev/lirc*
ls: cannot access '/dev/lirc*': No such file or directory

Did you load "meson-ir" driver?
Check "lsmod" output first.

Have you tried ir-keytable instead?

You can save it anywhere, you will likely need to install ir-keytable with apt.

Save it in the home directory.

Hi noobs4u,
lircd must be running if lirc configuration is done.
As I checked, there is no lircd in your list.

Code: Select all

odroid@odroid:~$ ps -ax | grep lirc

 3164 ttyS0    S+     0:00 grep --color=auto lirc

Here is my lirc_options.conf.
I think you already modified the conf file, but could you check your lirc_options.conf again?

Code: Select all

odroid@odroid:~$ cat /etc/lirc/lirc_options.conf
# These are the default options to lircd, if installed as
# /etc/lirc/lirc_options.conf. See the lircd(8) and lircmd(8)

# driver, device, plugindir and loglevel as fallback values
# in not defined elsewhere.

Aim the front of the remote at the camera in your phone, push the buttons and make sure it's working. You will see a light.

It should be working, ir-keytable bypasses lirc and directly uses the kernel.

Try this, run ir-keytable like this and press the buttons.

Code: Select all

sudo ir-keytable -t

If it's working it should detect button presses. Try your TV remote or any other IR remote you have lying nearby in addition to the HK remote

Are you sure the C2 IR sensor is facing toward you?

It's working, try the remote in Kodi

You should exit "ir-keytable -t" with Ctrl + c first of course.

I think we need to figure out the reason why lircd doesn't work normally with noobs4u's environment.
lircd can register uinput event via its interface and it may be working with KODI once lircd works normally.
I've tried to reproduce the issue with my environment but I couldn't.

I will try it again.

Hi rooted,
Weird....

Did you modify lirc_options.conf under /etc/lirc/ ?
https://wiki.odroid.com/odroid-c2/appli ... buntu18.04
After you modify it and restart lircd, you must find the node.

rooted · Unread post by **rooted** » Fri Jul 13, 2018 11:52 am

I restarted it twice, now I have it.

rooted · Unread post by **rooted** » Fri Jul 13, 2018 12:10 pm

One thing that's wrong is the plugin directory in the lirc_options.conf

In the wiki it says

Code: Select all

plugindir = /usr/lib/arm-linux-gnueabihf/lirc/plugins

But should be

Code: Select all

plugindir = /usr/lib/aarch64-linux-gnu/lirc/plugins

*edit*
This fixed the issue, it works now. Please update the wiki.

rooted · Unread post by **rooted** » Fri Jul 13, 2018 2:13 pm

Did you understand @joy?

@noobs4u

Change the line above and restart lircd and lircd-uinput then your remote should work.

In the wiki it says
Code: Select all
plugindir = /usr/lib/arm-linux-gnueabihf/lirc/plugins
But should be
Code: Select all
plugindir = /usr/lib/aarch64-linux-gnu/lirc/plugins
*edit*
This fixed the issue, it works now. Please update the wiki.

rooted,
You're right.
Really sorry for making this confusion.

I think I made this mistake because I should three wiki pages for XU4, C1 and C2.
This configuration is for XU4 system.

I've updated the wiki page.

And thank you so much.

@noobs4u,
Really sorry.
With the wrong conf option, now I can reproduce the problem as yours.

Code: Select all

root@odroid:~# service --status-all | grep lirc
 [ - ]  lircd
 [ - ]  lircmd

Could you try the updated lirc_options.conf as rooted mentioned?

Thanks joy, glad we got it resolved. I don't understand why ir-keytable method doesn't work but I will start another thread for that perhaps tomorrow.

Yes, please.
I'm not used to using ir-keytable so I wanna learn it this time.

@joy, Agreed.
@rooted, If you manage to work out the ir-keytable method for 18.04, I'd love to have the link to the new thread for it. Options are always best.

You're welcome.

The ir-keytable thread is here but I haven't figured anything out yet.
