Re: kodi & lirc

You don't need lirc with Rasbian Buster. It is handled by the kernel.

All you need to do is have the dtoverlay=gpio-ir in config.txt and done if you have a RC-6 MCE remote.

Re: Rpi4 - Extremely unstable ethernet connection

A couple of clarifications: If you have only seen two posts you have not been looking very hard. There has been a fair amount of discussion about the update, what broke and what you can do as work arounds until a fix is available. You can revert to the 4.19 kernel.

Re: Rpi4 - Extremely unstable ethernet connection

Was it working good before your last update? My Pi4 is now junk since the kernel was updated to 5.4. It kills at least one core and makes the Pi4 pretty much useless. My first indication was losing connection over ethernet frequently then incredibly slow transfers to HDD. I have been booting and run...

Re: udev rules don't run

Why would lirc need to be installed? Raspbian has had gpio-ir in the Kernel for a long time now. Installing lirc just confuses the OS. Also, the format of the conf files is different between ir-keytable (gpio-ir) and irrecord (lirc). https://www.raspberrypi.org/forums/viewtopic.php?f=66&t=277684...

Re: udev rules don't run

It is not "my" rule. It is installed when you install ir-keytable. It takes milli seconds to run. It exits with code 255 or 0, I think I understand they are the same.

It's function is to load the ir keymap.

Re: HOW TO install a gpio remote in Buster

Turns out most of the problem is trying to us old and cut and pasted tutorials. ALL of the lirc tutorials I found are WRONG for kernel 4.19 and above. Most of them are cut and pasted from 10 year old instructions with current dates. And the generic Linux ones have different paths and directory names.
