Allwinner H3 boards, use image on different board

[Christian_]

Good evening All.

I was wondering what is the best method to use an Armbian sd card born for an H3 based board on another board with the same SoC, e.g. Orange Pi 2 image on Orange Pi Lite.

With old 3.x kernel it was super easy, just replace the fex file and that's it.

Overlays confuse me a fair bit, and the best method I found until now is to specify in armbianEnv.txt the row fdtfile=sun8i-h3-orangepi-lite.dtb to use a sdcard loaded with an Orange Pi 2 image in my Orange Pi Lite.

But I cannot find where the board is defined, could anyone point me in the right direction?

 

Best Regards.

It is in the default U-Boot environment, the default fdtfile is declared in board defconfig...
