Boot with the Debian rootfs Debian-4.12.1-kirkwood-tld-1-rootfs-bodhi.tar.bz2 on USB. And then flash new u-boot.

Note: If this is your first time installation, then you need rootfs Debian-4.12.1-kirkwood-tld-1-rootfs-bodhi.tar.bz2 (this has kernel 4.12.1-kirkwood-tld-1 already installed).

d. Flash u-boot envs to NAND location 0xC0000.

Quote

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
md5:
3823eef10011b864859d31a76470e0e3
sha256:
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).

tar xf uboot.2016.05-tld-1.environment.bodhi.tar  -C /mnt/uboot/boot uboot.2016.05-tld-1.environment

On another Linux box, mount the Debian rootfs that you meant to run on this box and put the attached u-boot script in the /boot folder (if it was mounted at /media/sdb1): 

cp -a uboot.2016.05-tld-1.environment.scr /media/sdb1/boot/

kwboot this box and interrupt serial console, run the script loading commands: 

usb start
ext2load usb 0:1 0x800000 /boot/uboot.2016.05-tld-1.environment.scr
source 0x800000
printenv

1. uBoot envs config should be defined as followed in your /etc/fw_env.config 

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

- And your mtd partitions should be: 

cat /proc/mtd 
dev: size erasesize name 
mtd0: 00100000 00020000 "u-boot" 
mtd1: 00400000 00020000 "uImage" 
mtd2: 02000000 00020000 "rootfs" 
mtd3: 0db00000 00020000 "data"

root@debian:~# cat /etc/fw_env.config
# MTD device name	Device offset	Env. size	Flash sector size	Number of sectors
/dev/mtd0 0xc0000 0x20000 0x20000
root@debian:~# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00100000 00020000 "u-boot"
mtd1: 0ff00000 00020000 "ubi"

6. Erase mtd0 
flash_erase /dev/mtd0 0 4
Expected output:
