18.04 LIRCD failure [ BODGED]

[richard-g8jvm]

Hi
hitting a few probs with 18.04
its noticeably slower than 16.04
the time it take to ask ffor a password with sudo is long, 5ecs, with 16.04 it was instant]

Lirc installed as per wiki, but it refuses to run, the moduels are loaded for the HK remote, which I use
but

Any ideas ??? , what have I missed ?

[mad_ady]

There's a wiki entry for lirc on 18.04 for xu4. There are some changes you need to make to the config files to have it run.

Regarding sudo, it sounds like a name resolving issue. Have you renamed your odroid and did not add 127.0.0.1 newname[/] in /etc/hosts?

[richard-g8jvm]

Hiya
no name change, its still odroid.
Are you sure its for a XU4 ? as that doesn't have a IR sensor ???
I'll look anyway.
Thanks

[mad_ady]

It's somewhere in the add a ir blaster section.

[richard-g8jvm]

OK found that,
Its the same as the section in the C2 wiki, with serial modules loaded as its using GPIO

[richard-g8jvm]

Ive stopped trying to start LIRCD as a service, as it looks from what i'm finding that systemd has been a bit knobbled, to encourage the use of systemctl

So I've run sudo systemctl enable lircd
and rebooted as I did with getting motion to start, which it did.

and now getting a different status message:-

Code: Select all

odroid@odroid:~$ sudo systemctl status lircd

There is also something very screwy here, the ciniparser line is rejecting a line with a "#" at the start
I put that there to stop the comment !
it should not be reading a line with a hash at the start.
It also looks like the use of "service start"in the wiki may be incorrect.
with this kernel and ubuntu18 using "service start lircd" results in systemd not having permissions or something like that to write to files in /var

[richard-g8jvm]

There is something definitly wrong with lirc

Just in case I'd imported a non displayed character , I copied the lirc_options.conf file again from the Wiki, straight copy and paste
re-enabled lircd with systemctl
Ran systemctl start lircd
sytemctl status lircd shows:-

NOTE ciniparser still shows the last line is too long
You can put a hash in front of this line so it should not be read, but it still is !
the new conf file does not have the preamble the distributed file has , hence it lists line 30 and not 37
Considering that up to now the HK remote would function with the supplied image, in other words lirc was configured by default.
Why change this practise, unless its known that LIRC does not work with ubuntu 18.04 arm64 ???
Lirc works well on Ubuntu16.04, but the diectory structure has change on 18.04 , so have the config files.
I'll ask on the lirc list and see if this is known there.

[richard-g8jvm]

Hi
This problem is well known about !!!!!!
The version of lirc distributed with ubuntu LTS 18.04 is BROKEN
see https://ubuntuforums.org/showthread.php?t=2396923
Following the link given in the reply to that posting:-
the depositoty to be added to /etc/apt/sources.list is

Code: Select all

deb http://ports.ubuntu.com/ubuntu-ports xenial main universe

loading lirc version 0.9.0 , the config file from the wiki should be that of ubuntu LTS 16.0
rename the original hardware.conf and lircd.conf , and copy the files over from the wiki to /etc/lirc

I started lircd with sudo lircd
running irw I get

It appears to auto start on boot up as well
and the remote works on kodi.

Just a shame the hardkernel guys couldn't say , "We know lirc 10.0.2 is broken , that s why its not included in the image"

[mad_ady]

Actually lirc comes from cannonical

[richard-g8jvm]

Hi mad_ady
its still broken and known about, which begs the question about the contents of the wiki.
Its not only me saying is broken,
Considering that a lot of the SBC odroids end up as media centers, kodi etc, where a remote is important, and that Hardkernel make and sell the remotes for this
and the other odroid boards which have IR sensors, it should have been checked, its slipped through the net.
Its probably due to the old kernel versions used and available for arm boards, Lirc 10.0.2 might work with later kernels, 4 and later.
I can safely assume you knew nothing of it, otherwise you would have said straight away, but someone at hardkernel must have known about it.
At least there is a work around that can be used on the C2, probably the others too.
The help you give is appreciated by all -thanks

[mad_ady]

Yeah, I'm only using it for an ir blaster, not a receiver, so I can't comment.

[odroid]

Is there something to be updated in this instruction for Ubuntu 18.04?
https://wiki.odroid.com/odroid-c2/appli ... buntu18.04

[rooted]

It should have been checked, its slipped through the net.

There is no way to check every subsystem of every os release with their limited resources unfortunately.

I setup lirc without downgrading lircd a month ago. It was broken due to a configuration error on the wiki, I figured out it was simply a path problem and the wiki was updated to reflect this.

[richard-g8jvm]

Hi
since that time there is a new kernel for arm64, and it looks as if the use of "service START|STATUS| etc <service type>"
has been depreciated.
Its forcing the use of "systemctl" to start sevices.
This is applicable to services that used to start with "service start"
The kernels used on odroids are pretty ancient, the computer upstairs runs on 4.17, this laptop uses 4.15
Port naming is still eth0, wlan0 etc, whereas thats has been superceeded by enp9s0 and wlp12s0, examples from my laptop running linux mint which
uses ubuntu 18.04, but with cinnamon as a DM
I do get the impression when I post something the Odroid developers just regard it as "that F'ing idiot posting rubbish again "
I'm very grateful for the help of mad_ady for the help he gives.
It is a fact that when packages are a new version and ported to other architectures and used with old kernels there are likely to be be problems,
and LIRC has been flagged on other distros as having problems with the newest version 10.0.2.

I'll probably get told to leave the list for criticising now

[rooted]

I'm not affiliated with Hardkernel, I was just saying when the image was released and no less than 30 days ago lirc was working fine.

So there is really no way they would have known it's now broken without someone like you telling them. This is an Ubuntu issue not Hardkernel, they don't maintain that package.

mad_ady is great, I also do my best to help people when I can. I don't believe any hardkernel developers have said anything negative to you, they are all patient, helpful people.

An updated 4.18 based kernel for the C2 is close to release.

viewtopic.php?t=22717

[richard-g8jvm]

Glad to hear a 4.18 kernel is not too far away.
Its not a ubuntu problem, as its several distros that have been effected; the fickle finger of fate points clearly at LIRC
Maybe when kernel 4.18 comes on line LIRC 10.0.2 may work, or more likely 10.0.4 with all the bug fixes will.

[spipnl]

If anyone is googling and lands on this forum (like me). I have found a solution for this problem.
The error message is found in the source on the following line:
https://github.com/rustyrussell/ccan/bl ... ser.c#L410
The error is thrown after the check on line:
https://github.com/rustyrussell/ccan/bl ... ser.c#L408
There is an explicit check for a newline at the end of the config file.
Adding a simple newline in the config file fixes the problem.
