Hi,
For long (long) time I did not update my nano pi duo image, recently I changed microSD card and wanted start fresh with latest image.
I have tried latest debian image and also tried building image for the BOARD target as `nanopiduo`, but in in both cases my board is stuck at ...

In older images, CPU was detected as `Allwinner H2+`, however now it's detecting as H3.
I have tried couple other SD cards, with same error.
What config I can try to get my `nanopi duo` working?
offtopic: I tried images available from friendlyelec drive, which are getting stuck at "Starting kernel".
