For easier debugging, support WiFi, I have collected new images Armnian (Ubuntu Mate). This system is NOT yet intended for full video playback. This way is convenient for debugging and testing of the various modules and settings. To use. To download an image, burn to media, you can activate the multi-boot. All operations in the same way as when using LE. Pay attention to one difference - to start, you must be sure to manually add the correct dtb file (dtb.img) to the root of the FAT partition (you can choose from existing files on the media in the directory dtb). For WiFi settings you need from the terminal to boot to the desired module. For example "sudo modrobe dhd". Details initial settings Armbian to run the system can be read on the forum Armbian (the principles are the same for all models s8xxx and s9xxx). That would make work wifi network, You can freely in the working system to change\add configuration files to add / change files, firmware, etc. once You get a working configuration, it will be possible to port it to LE and assemble a working image LE.
Is it technically possible to use Kszaq's 905 strategy of making builds that you burn and add the correct dtb to?
I just used it on a few 905x devices and it's a very flexible approach.
