Notes

The Storage has 3 Partitions The first Partition contains: the kernel, device-tree, two boot-scripts and the Debian-Installer initramfs

The Bootloader Environment is stored to boot a bootscript from the fat partition. The script is stored to the environment $script variable and can be saved with the saveenv command. As default the variable is set to boot.scr.

The delivered partition contains a boot.scr.install (Debian Network Installer) and a boot-debian.scr script. The debian installer can be activated by: copying the boot-debian.scr to boot.scr or by setting the script environment variable in uboot. boot.scr can also be a copy of boot-debian.scr to boot normally into the preinstalled Debian rootfs.

After

mmc env_erase <CR>

the Bootloader falls back to boot boot.scr. The boot.scr can be a copy of boot.scr.install which loads the Debian-Installer or of boot.debian.scr.

Feel free to use the pre-installed Image or re-install another config with the debian-network-installer.

Example so save the script variable:

setenv script boot-debian.scr <CR> 
saveenv <CR>
reset <CR>
