Hi,
I have started to work on a Nanopi Neo3 Plus image (rk3528-based, similar to Nanopi Zero2), announced early March 2026.
Created a new .csc file, used the Nanopi Zero2 as a template. Built it with the vendor version.
Built it with the vendor kernel., but added the "dt" directory with the rk3528-nanopi-rev02.dts to be "automatically" added to the dts directory and Makefile.
The base console version seems to work ok when I generate a bookworm image.
As I currently only need u-boot, kernel and dtb's to build my own OS (Volumio, volumio.org), it works for me.
Of course, I would like to contribute my work (and support it?), but how do I proceed?
I used Armbian's kernel and u-boot build a lot, but not done this before.
