# U-Boot with the datachk patchset requires image sizes, offsets,
|
|
# and checksums to be provided in the U-Boot environment.
|
|
# This script is based on the dualboot version for devices that come with 2 OS partitions.
|
|
# For Senao boards with a "failsafe" partition image, the process is almost the same.
|
|
# Instead of booting a secondary instalation on checksum failure,
|
|
# the failsafe image is booted instead.
|
|
# These boards also use the OKLI lzma kernel loader and mtd-concat
|
|
# So the kernel check is for the loader, the rootfs check is for kernel + rootfs
