December 20, 20223 yr Hi, This is my first try to add a board to armbian build system. I got a BPI M2S since several months, but only had time recently to investigate on this promising SBC. I made a PR here, if somebody wants to try it: https://github.com/armbian/build/pull/4597 The main improvements are to be done for the dts file, since I'm not an expert about such file definition. Only 1 ethernet of the Gbit ports is working, since I copy the config from vim3 that share the same hardware for it. I didn't try to customize u-boot and I use the one for radxa zero2 that works to launch armbian on the board. armbianmonitor -u is here: https://paste.armbian.com/piyuqajeye
December 31, 20223 yr As it shares the A113D do you think it would work with the BPI-CM4 too? https://wiki.banana-pi.org/BPI-CM4_Computer_module_and_development_Kit
January 2, 20233 yr Author Hi, I don't have this board, but since it is from the same manufacturer, we can hope that the 2 boards share similar elements. For instance, the GbE ship is the same (RTL8211F), the same amount of emmc and ram. If you have the base board and an sd card, you can try to boot it. If you don't want to build an image by yourself, you can start by trying the Radxa zero2 image that was able to start my M2S board.
January 4, 20233 yr They are not available beyond developer preview yet. I'll try once they are available
January 21, 20233 yr I found bananapi cm4 and m2s armbian build github supported by its official maintenancer, https://github.com/Dangku/armbian-build/. Edited January 21, 20233 yr by longsd wrong word

Good find! They fork armbian and add the board differently. I'll look at this to check how to take the good part from it. My main issue is about the second ethernet port (RTL8111H), for which I don't see how to make it work. I tried several device modifications but without any success.
January 25, 20233 yr I have built the BananaPI CM4 Image. It's ok to boot, but audio failed due to some DTS problems. This may be one point that Bananapi official Image not fully released for now.

The second ethernet port was working, so I'm studying the device tree to check what is missing in mine.
