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

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 Reading package lists... Done Building dependency tree Reading state information... Done lirc is already the newest version (0.10.0-2). 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. odroid@odroid:~$

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.

Removed lirc and installed again:

Remote still does not work.

Did you follow the WiKi instructions?
https://wiki.odroid.com/odroid-c2/appli ... controller

I have followed the wiki, so many things missing from a new image install...

Tried even to do a custom remote, got this error:

Have you tried ir-keytable instead?

See my post here:

viewtopic.php?f=144&p=176534#p176534

by **noobs4u** » Thu Jul 12, 2018 11:31 am

which directory does this get saved in?

by **rooted** » Thu Jul 12, 2018 11:42 am

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

Save it in the home directory.

by **joy** » Thu Jul 12, 2018 12:28 pm

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 3145 ? Ss 0:00 /usr/sbin/lircd --nodaemon 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) # manpages for info on the different options. # # Some tools including mode2 and irw uses values such as # driver, device, plugindir and loglevel as fallback values # in not defined elsewhere. [lircd] nodaemon = False driver = default device = /dev/lirc0 output = /var/run/lirc/lircd pidfile = /var/run/lirc/lircd.pid plugindir = /usr/lib/aarch64-linux-gnu/lirc/plugins permission = 666 allow-simulate = No repeat-max = 600 #effective-user = #listen = [address:]port #connect = host[:port] #loglevel = 6 #release = true #release_suffix = _EVUP #logfile = ... #driver-options = ... [lircmd] uinput = False nodaemon = False [modinit] code = /sbin/modprobe meson-ir [lircd-uinput] add-release-events = True release-timeout = 50 release-suffix = _EVUP

https://wiki.odroid.com/odroid-c2/appli ... ver_module

And please try "service lircd restart" again.

Code: Select all: odroid@odroid:~$ sudo service lircd restart odroid@odroid:~$ service --status-all | grep lirc [ + ] lircd [ - ] lircmd

by **noobs4u** » Fri Jul 13, 2018 3:03 am

Code: Select all: odroid@odroid:~$ service --status-all | grep lirc [ - ] lircd [ - ] lircmd odroid@odroid:~$

I see you had a + and -, both mine are -

by **noobs4u** » Fri Jul 13, 2018 4:42 am

So I re-imaged. Followed the lirc guide for Ubuntu 18.04 to install and register lirc and HK remote. When it came time to test, irw gave me this:

Code: Select all: odroid@odroid:~$ sudo service lircd restart odroid@odroid:~$ sudo service lircd-uinput restart odroid@odroid:~$ irw Cannot connect to socket /var/run/lirc/lircd: Connection refused

daemon check:

service status:

Code: Select all: odroid@odroid:~$ service --status-all | grep lirc [ - ] lircd [ - ] lircmd

Results are much better, but it looks like the daemon isn't running...

by **rooted** » Fri Jul 13, 2018 4:49 am

Did you try ir-keytable?

by **noobs4u** » Fri Jul 13, 2018 4:56 am

not yet, the daemon isn't running

by **rooted** » Fri Jul 13, 2018 4:57 am

You don't need lirc for ir-keytable, it's why I recommended it.

Code: Select all: wget https://www.dropbox.com/s/66x8elis49i5ab9/remote.conf?dl=1 -O remote.conf sudo apt install ir-keytable sudo ir-keytable -c -w remote.conf

by **noobs4u** » Fri Jul 13, 2018 5:00 am

Good times!

Code: Select all: odroid@odroid:~$ ir-keytable -c -w remote.conf Read odroid table Old keytable cleared Wrote 12 keycode(s) to driver /sys/class/rc/rc0//protocols: Permission denied Couldn't change the IR protocols

by **rooted** » Fri Jul 13, 2018 5:06 am

It should. It's been a while since I used the Hardkernel remote.

Run it with sudo

And try the remote.

remote still not operating...

by **rooted** » Fri Jul 13, 2018 5:18 am

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.

by **noobs4u** » Fri Jul 13, 2018 5:21 am

yep, little lights are flashing when I hold down any number of buttons...

by **rooted** » Fri Jul 13, 2018 5:26 am

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?

by **noobs4u** » Fri Jul 13, 2018 5:32 am

It's working, try the remote in Kodi

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

by **rooted** » Fri Jul 13, 2018 8:57 am

Did it work?

I don't understand how it isn't working, the remote is programmed and functional.

I will try and figure it out and post back.

by **joy** » Fri Jul 13, 2018 10:43 am

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.

by **rooted** » Fri Jul 13, 2018 10:51 am

I'm installing Ubuntu 18 now.

by **joy** » Fri Jul 13, 2018 11:02 am

Could you try this command?
And please share the result.

Code: Select all: $ mode2 -d /dev/lirc0

If you have

Code: Select all: mode2: could not open /dev/lirc0 mode2: default_init(): Device or resource busy

please do this and then try irrecord.

Code: Select all: $ sudo kill `pidof lircd`

Code: Select all: $ sudo irrrecord --device /dev/lirc0 lircd.conf

If you still have the same issue, could you share /var/log/syslog file here?

by **rooted** » Fri Jul 13, 2018 11:29 am

@joy

There is no /dev/lirc0 after following the instructions in the wiki.

A quick look at dmesg

Code: Select all: rc0: meson-ir as /devices/c8100580.meson-ir/rc/rc0

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.

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

I restarted it twice, now I have it.

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.

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.

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.
https://wiki.odroid.com/odroid-c2/appli ... ver_module

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?
