I have a same box as yours. I use a dtb here , named eachlink h6 mini.dtb by @jernej
I write the @balbes150 's image to sd cards . The box boots with armbian , but cannot connect to the interent , by Ethernet or Wifi. The system find no internet device.
So is there any perfact dtb for this IMG , or any IMG for this dtb?
