R-Pi with Xbox remote: can't get gpio-ir working

    Hi all,

    I'm doing my first steps with LE, on a Raspberry Pi 3. LE version 8.2.1 is installed.

    I want to use the XBOX One remote controller (NEC protocol). On GPIO18, a Vishay IR receiver is connected. There is a keymap file /etc/rc_keymaps/xbox_one which seems to be suitable.

    To config.txt I added

    dtoverlay=gpio-ir,gpio_pull=up,rc-map-name=xbox_one

    But this doesn't work:

    [ 4.325490] rc rc0: gpio_ir_recv as /devices/platform/ir-receiver/rc/rc0

    [ 4.358206] rc_core: IR keymap xbox_one not found

    [ 4.358215] Registered IR keymap rc-empty

    I put a copy of xbox_one to /etc/rc_keymaps/, same result.

    I changed to rc-map-name=rc-xbox-one, since this is the driver table name given in /etc/rc_maps.cfg, still same result (rc_core: IR keymap rc-xbox-one not found)

    The pull-up setting seems also to be ignored, since the high-voltage is still only 1.9 V. I therefore added a 10 k resistor, which puts it to 3.1 V.

    Calling ir-keytable shows:

    Driver gpio-rc-recv, table rc-empty

    enabled protocols: lirc

    Applying ir-keytable -c -p nec -w /usr/lib/udev/rc_keymaps/xbox_one

    puts the remote to work, with correct key assignments in KODI. But ir-keytable -t still doesn't show any events...

    Calling ir-keytable now shows:

    Driver gpio-rc-recv, table rc-empty (same as before)

    enabled protocols: lirc nec (nec added)

    What is the correct way to specify the xbox-one keymap / NEC protocol with gpio-ir?

    Thank you!

    Drop the rc-map-name DT parameter. Without that gpio-ir will default to the rc-rc6-mce table and LE will apply a default config that supports the xbox one remote out of the box.

    so long,

    Hias

    I wonder why the pull-up setting was ignored, is it correct syntax?
