8. Flashing default u-boot envs image (if you are upgrading from 2016.05-tld-1 u-boot, you can skip this step 8).

As described in step 1, u-boot envs must be defined in /etc/fw_env.config as

# MTD device name Device offset Env. size Flash sector size Number of sectors
/dev/mtd0 0xc0000 0x20000 0x20000

This default envs image supports booting with multiple disk drives (and hubs) attached. The disk drives could be any type (usb, sata, sd card). The scanning logic and default envs were set to automatically boot the box with the following required configuration:

For whatever reason, if you can't set up your configuration to satisfy the following 4 requirements, then don't flash this defaut envs image. It might not boot properly. In this case, section C below can be used to tailor the envs to your specific configuration.

r1. There must be only one partition among all partitions from all drives that contains the kernel files. The 2 kernel files are /boot/uImage and /boot/uInitrd.
r2. The partition that contains the 2 kernel files must be partition 1 in a disk drive
r3. The partition that contains the rootfs must be labeled rootfs
r4. The rootfs partition is recommended to be type Ext3 (this is not a hard requirement, ext4 should boot OK, but Ext3 will ensure no problem).

So the bottom line is if you have only one rootfs in a single Ext3 partition, which is labeled as rootfs, then you're all set.

a. Download the default u-boot envs at Dropbox:

uboot.2016.05-tld-1.environment.bodhi.tar

c8db95a4225e8d78bdaaaa372bd5a87e4b98f3448dd9c62fc96c72b2df1a997c

This tarball includes 3 files:

uboot.2016.05-tld-1.environment.img (the default envs image to be flashed)
uboot.2016.05-tld-1.environment (the content of the default envs in text format)
uboot.2016.05-tld-1.environment.64K.img (small envs image to be flashed on HP T5325 only).
