ZyXEL NSA325 booting problem

I have a serial cable and trying to boot from USB because of impossible
to boot from NAND after flashed uboot.2016.05-tld-1.nsa325.bodhi.tar
USB was formatted as ext4 with boot flag and rootfs label, then just copied
a content from Debian-4.4.0-kirkwood-tld-1-rootfs-bodhi.tar.bz2

Sounds like you need to set the appropriate dtb file.

purportex,

1. You did not flash the default envs image, that's why your envs has error

Quote

*** Warning - bad CRC, using default environment

2. And that caused u-boot to use its internal settings, which does not have the DTB location.

Solution:

See here for a similar booting problem and solution:

Yes this is the problem with missing u-boot env to boot with the device tree DTB.

1. You have missed this section and did not flash the default envs image:

Quote

8. Flashing default u-boot envs image:
............
. A special section (B. Flashing default u-boot envs image) about flashing default u-boot envs is included at the end of this installation procedure. Please follow the instruction in this section B to perform this step before continuing with step 9.

So that was why the DTB was not setup properly.

2. To fix this, go a head and download the env image tarball:

Quote

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

uboot.2014.07-tld-3.environment.bodhi.tar
md5
8d53c30918510e0f1ea89d889a3f6f8e

This tarball includes 2 files:

uboot.2014.07-tld-3.environment.img (the default envs image to be flashed)
uboot.2014.07-tld-3.environment (the content of the default envs in text format)


3. Boot with your rootfs into Debian, create a uEnv.txt file (if you can't boot then mount this rootfs on another Linux box and create this file):

cd /boot
cp -a uboot.2014.07-tld-3.environment uEnv.txt

4. Edit the uEnv.txt to adjust the DTB name

Quote

dtb_file='/boot/dts/kirkwood-nsa310.dtb'

Also adjust other envs if you like to do so now. But just the DTB and the rootfs label env in this default image, will get it boot into Debian.

5. Then sync and reboot

This uEnv.txt will be in effect during boot only. So after booting into Debian, flash the default env image using the instruction in section B.

In your case, use the uboot.2016.05-tld-1.environment file, and copy it to uEnv.txt. Adjust it to use kirkwood-nsa325.dtb.
