Read this first: Upgrading u-boot on SheevaPlug
You must manually preserve your ethernet address
$ nix-build uboot.nix -o uboot
Install from linux:
$ flash_erase /dev/mtd0 0 0
$ nandwrite -p /dev/mtd0 u-boot.kwb
If this goes wrong, you can recover via jtag with openocd.
$ nix-build sheevaplug-system.nix -A config.system.build.sdImage -o sdImage
$ bzcat sdImage/sd-image/*.bz2 > /dev/$sdcard
The contents sd-image-sheevaplug.nix are almost identical to
upstream sd-image-aarch64.nix and
sd-image-armv7l-multiplatform.nix, the main differences are
- no raspberry pi support
- smaller set of dependencies required
