Hey everyone,
I was looking around in an attempt to find some more info about the D1 Nehza and stumbled across the RV Boards forum. They have a section on all about the Nehza.
All the posts are in Chinese, but Google Chrome and Microsoft Edge are capable of in-place translation of the web page (sadly Firefox does not have this feature).
There is a user named liangdi who has a series of posts called "Happy Hacking Nehza Board" that cover some basics for building code for the D1. While a lot of the people here seem to be already very skilled in working with the Linux kernel, I figured that some people here might find it useful (such as myself, who has never compiled the Kernel before).
From another post on the forum, I have gathered that RVBoards is planning on eventually releasing the source code for their Debian port, which will probably be very helpful.
