Hey, is it possible to install your LE to eMMC on s905?
Sure, you can easily do this with the installtointernal script.
If yes, would making a backup of eMMC with Armbian's ddbr or Khadas Rescue preserve the firmware and bootloader/config?
Unfortunately, I haven't used these yet, so I can't comment.
The uboot bootloader parameters can be checked with fw_printenv under my images. However, the installtointernal script does not modify the uboot bootloader or its parameters, it only modifies these partitions:
- /dev/boot: kernel partition,
- /dev/system: the SYSTEM file (root squashfs) goes here, it is mounted as /flash under LE,
- /dev/dtb: the DTB's partition,
- /dev/data: this is data particion, it is mounted as /storage under LE.
