NUC10 + LE13 Nightly Generic - IR Remote not working

adam.h. · June 15, 2024 at 12:09 AM

nightly-20240613-18becd8 - remote is not working with this one (no reaction to any button)

nightly-20240612-1a71ae6 - remote is back to normal

Perhaps this is the reason:

Code

On my RPI 4B the IR Remote also stopped working after upgrade to LibreELEC-RPi4.aarch64-13.0-nightly-20240614-18becd8

Analyzed the issue a bit and it looks ir-keytable does not see the rc0 device anymore but rc1 instead in my case.

ls /dev/lirc*
/dev/lirc0 /dev/lirc1 /dev/lirc2

ir-keytable

Found /sys/class/rc/rc1/ with:
Name: gpio_ir_recv
Driver: gpio_ir_recv
Default keymap: rc-rc6-mce
Input device: /dev/input/event3
LIRC device: /dev/lirc1
Attached BPF protocols:

bus: 25, vendor/product: 0001:0001, version: 0x0100
Repeat delay: 500 ms, repeat period: 125 ms
Found /sys/class/rc/rc2/ with:
Name: MyGica Mini DVB-(T/T2/C) USB Stick T230C
Driver: dvb_usb_dvbsky
Default keymap: rc-total-media-in-hand-02
Input device: /dev/input/event4
LIRC device: /dev/lirc2
Supported kernel protocols: rc-5
Enabled kernel protocols: rc-5
bus: 3, vendor/product: 0572:c689, version: 0x0800
Repeat delay: 500 ms, repeat period: 125 ms

As the default device is still /dev/lirc0, then some commands like irw does not work.

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 = /run/lirc/lircd.socket
pidfile = /run/lirc/lircd.pid
plugindir = /usr/lib/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 = ...

[lircmd]
uinput = False
nodaemon = False

# modinit is not supported in LibreELEC

# [modinit]
# code = /usr/sbin/modprobe lirc_serial
# code1 = /usr/bin/setfacl -m g:lirc:rw /dev/uinput
# code2 = ...

irw
Cannot connect to socket /run/lirc/lircd: Connection refused

The /etc/lirc/lirc_options.conf file is read only and currently I don't know how to easily change the device configuration to /dev/lirc1 as the shadow file in /storage/.config/ folder did not help.

But maybe it's a wrong way anyway...

This is the fix: https://github.com/LibreELEC/eventlircd/pull/4

EDIT: It still needs some work, but we're aware of the issue and it will be resolved.

EDIT2: Now resolved, so next nightlies should contain the fix.

Great, thanks for a quick fix!

Can someone please trigger nightly build for x86 as well?

btw. I always had impression that nightlies are triggered via some automation if at least one PR is merged during a day? But it seems that they are triggered somehow randomly, otherwise we should see 5 builds during June 11-15 and this would be consistent for all device types:

In the ideal world all our PR's compile without issues, all the dependant services have 100% uptime, and all the build servers have infinite disk space. Reality is often different.

Thanks chewitt, just verified that the fix works on x86 as well.
