Pine A64+ IR Remote not working

I've installed the latest nightly build of LibreELEC for PineA64+, version 20220213.

It works fine, except for Wi-Fi module and IR remote.

For the first, I'm using the Ethernet cable, so i've resolved.

For the IR Remote, I've made steps in this page:

LibreElec Configuration IR-Remotes

But I got:

ir-keytable
No devices found

How can I use the IR Remote on my Pine A64+?

Pine A64 SBC

As you can see on this image, there is a IR Receiver port. I've used a simple IR receiver on this port, a TSOP4840.

Thanks jernej - I' hadn't understand on first reading of your reply. So, I've added the code inside the file extlinux.conf, before the line with command FDT like below:

LABEL LibreELEC
  LINUX /KERNEL
  FDT /sun50i-a64-pine64-plus.dtb
  FDTOVERLAYS /overlays/sun50i-a64-ir.dtbo /overlays/sun50i-a64-pine64-wifi-bt.dtbo
  APPEND boot=UUID=1302-1252 disk=UUID=79a06ea9-ed8f-4364-b22a-b1f873446521 quiet console=ttyS0,115200 console=tty1

Now I'll try to start with this configuration.

Thank you jernej it works. I've got the command ir-keytable with protocol rc-5 with signals.

I've mapped the FBPC100A, the remote control for Technisat SkyStar USB DVB-S2 decoder, actually unused.

Now I'm trying to use it with LibreELEC. May I continue to require help here, or does I must to create another thread?

Ok, so I've created a file named /storage/.config/rc_keymaps/fbpc100a.toml. It contains as described on this pastebin link: fbpc100a.toml

So inside the file /storage/.config/rc_maps.cfg theres is this line: *  *  fbpc100a.toml

But when I've reboot PineA64+ I cannot use the remote control, the keys KEY_UP and KEY_DOWN does not move inside interface.

May I've lost something?

I've found my issue.

1. There was some code duplicated inside .tolm file; using the command:

ir-keytable -c -w /storage/.config/rc_keymaps/fbpc100a.toml

I got this error; so after I've corrected the config file, the IR Remote works like a charm. So this command is essential in order to use the configuration with lircd.
