09. CoreELEC: Troubleshooting

Scenarios

• When trying to read IR key codes by executing the command ir-keytable -u returns error: /sys/class/rc/: No such file or directory. No devices found

• No input shows when running dmesg -c

Troubleshooting steps

Prior to trying any of the troubleshooting steps below, it is recommended to remove the batteries from the remote for about 1 minute.

After 1 minute, reinsert the batteries. This will "reset" the remote.

1. Test the IR remote with a camera. (1)

   Test the IR remote with a digital camera connected to a diplay, such as for example a mobile phone, tablet, webcam or DSLR camera:
   

   Point the remote at the camera lens, then push a remote button. If the IR transmitter LED turns on or flashes in the display when pressing a key on the remote, the hardware is functional.
   

   IMPORTANT: For Bluetooth remote controls, use the green power button to test for an IR signal.

2. Remove ALL instances of Meson_IR and AmRemote configuration files from /storage and /flash partition.

   IMPORTANT: The meson-ir driver can only load in absence of remote.conf

   To make /flash accessible run in ssh:

   mount -o remount,rw /flash

   OR

   remove SD/Emmc and mount to PC, then delete remote.conf from root.

3. Reboot / restart / startup the device once all configuration files have been removed.

4. ssh into the device:

   ssh root@<ip_of_device>

5. Stop kodi and eventlircd:

   systemctl stop kodi
systemctl stop eventlircd
   

6. Try:

   ir-keytable -u (2)
   ir-keytable -u -v
ir-keytable -p NEC,RC-5,RC-6,JVC,SONY -t
   

7. Another way is to "reset" the decoder status by removing these files:

   /flash/remote.disable
/storage/.config/remote.disable
   

8. Meson-ir also can be forced by touching (3):

   /flash/remote.force_meson_ir
/storage/.config/remote.force_meson_ir
   

If after trying all of the above, there is still no output on the console when pushing buttons on the remote, it is likely the IR transmitter is incompatible or the receiver broken.

9. To provide a debug log type:

   remoteinfo

NOTES:

(1) Some digital cameras can't be used because they have a filter built-in that removes IR light. Try a different device.
(2) ir-keytable -u starts the IRMP decoder containing most of the known IR protocols.
(3) this should make the presence of (a) remote configuration file(s) irrelevant.
