Since (as I have written above) Kodi is not running at all, this log file is not available. Also I'm not sure if kodi.log contains what I need.Can you confirm that kodi.log would contain messages from the kernel about tuner card drivers?
If you just need an add-on of Kodi, then you'll see the errors, warnings etc. generated by that add-on. You can run LE non-headless for testing, if no kodi.log appears headless - I'm not sure about it.
