====== XU4 and XU3-Lite have no energy sensor on board ======

So you always meet this error message in the Kernel boot process.

If you don't like that annoying message, add the driver module in the black list.

 sudo nano /etc/modprobe.d/blacklist-odroid.conf 

Just add this line in the odroid blacklist file.

 blacklist ina231_sensor 

The annoying message will disappear.
