LIRCD / Remote Problem since Updating to Version 8

P3pp3Rde · February 24, 2017 at 4:25 PM

hi!

i have a
- ONEFORALL URC 7962 and a
- zbox nano.

everything worked fine until the update.

i checked

this looks quite ok!?

i have no idea where to start searching.
any ideas?

Hi,

same for me, with version 7 work flawless.

I have a mac mini with an harmony.

not sure what i have to check but:

Code

LibreELEC (official) Version: 8.0.0
Lemini:~ # ir-keytable
/sys/class/rc/: No such file or directory
Lemini:~ # cd /dev/input/
Lemini:/dev/input # ls
event0 event1 event2 event3 event4 event5 mice

so seems that LE can't see the remote interface.

But if I configure the Harmony to act as apple remote it works.

So any hint? Should i provide some logs?

I try to rollback to 7 and works, again clean install from USB to 8 (so not upgrade) and again not work... 7 again with HDD format and it works, upgrade to 8 nothing.

I downloaded the log files but i don't know what i have to share (all?)

well. that does not really seem to be the same problem, as ir-keytable does not list any input devices on your machine.

Could you upload the full dmesg (just do "dmesg | paste" and post the URL) and lsmod output?

Are you using userspace lirc (i.e. have you create a lircd.conf in the .config dir)? Are you running ir-keytable or other commands via http://autostart.sh/udev rules/... to setup a custom remote configuration? Which protocol/configuration are you using on your oneforall remote, is it MCE?

If you are using the nuvoton IR receiver (of your zbox) and the remote configured to (rc6) MCE protocol could you try running "ir-keytable -p rc-6 /sys/class/rc/rc0/" (double check if rc0 really is the nuvoton, it could also be rc1 since you have 2 IR receivers installed) and test if you get any events via "ir-keytable -t"?

It's quite odd that on the nuvoton IR the only enabled protocol is lirc and not lirc + rc-6. The kernel should enable the rc-6 protocol from loading the rc-rc6-mce keymap. But there's also a kernel bug, even if it enables the rc-6 protocol it didn't load the rc-6 protocol decoder - so decoding doesn't work. Manually enabling the protocol (eg via ir-keytable -p) triggers protocol decoder loading and decoding works fine again. I've already reported that bug and it was confirmed: Bug: decoders referenced in kernel rc-keymaps not loaded on boot — Linux media

so long,

Hias

Hi Hias,

THANKS!

in .config there actually really is a
-rw-r--r-- 1 root root 0 Feb 2 2016 lircd.conf
but its empty.

your command produced a strange output
mediacenter:~/.config # ir-keytable -p rc-6 /sys/class/rc/rc0/
ir-keytable: Too many arguments
Try `ir-keytable --help' or `ir-keytable --usage' for more information.
Protocols changed to rc-6

seems it set rc-6 for all devices.

but nevertheless: good WORKaround

Thank you
[hr]
created a

/storage/.config/autostart.sh with
#!/bin/bash
# added temporarily for libreelec 8.0.0
ir-keytable -p rc-6

works. will check again with new version of libreelec.

Then better remove it

ah, sorry, that should have been

Code

ir-keytable -p rc-6 -s rc0

Could you disable the autostart.sh and test if this 8.0.1 preview build works:
LibreELEC-Generic.x86_64-8.0.1.tar

so long,

Hias

Hi! Sorry. Cant.
This is our "production" environement
Can't risk the house blessing beeing crooked, again.

mwi · March 14, 2017 at 7:32 PM

@HiassofT
I have the same problem (my remote being "dead" after upgrading to 8.0)
I tried your build and there has been no change. The system still does not respond to the remote control.

nicolaberndt · March 20, 2017 at 6:19 PM

I also just freshly installed 8.0 on a X86_64 platform and don't get lirc to work.

I use a lirc-server in the network and starting lirc from autostart like this helps to get irw showing me all the keypresses:
mkdir -p /var/run/lirc
/usr/sbin/lircd -c infrared-pi -O /storage/.config/lirc/lircd_options.conf /storage/.config/lirc/lircd.conf

..just kodi is not picking it up, it used to work for me like that.

You also need to run lircd-uinput (adding the --uinput option of lircd might still work, but this is deprecated). See for example the lircd start script of LE:
