why rename it to dts? i'm sure you mean dtb, and I'm guessing because 
armbian loads that per default.

Not exactly sure, are you using the correct lime ;)

It does look like the correct dtb was used, since the second mmc 
controller is available. Maybe the bootloader prepares/inits something

changes?
