I am using latest nightly for RPi4 and got argon 1 case with IR.
I set up the keymaps file in /.config/rc_keymaps/ folder and also edited /.config/rc_maps.cfg to show "* * kodi" and kodi is name of the file I made for keymaps.
however it only works if I type "ir-keytable -p nec" after sshing to the Pi.
then it works until need boot when i have to re do the command to make it work.
anyone know fix on how to make it permanent?
