[solved] Troubleshoot booting Zyxel NSA310s (netconsole) (no replies)

UPDATE 1:
The device boots with success from a 2TB mbr disk.

UPDATE 2:
After recreating the GPT table on the 3TB, it appears that my problems are solved.
(I had mucked with the old GPT, hoping that stock uboot would support hybrid MBR)

Hello All,

- Zyxel nsa310s
- SATA disk is 3TB gpt with rootfs

Yesterday I flashed with success uboot.2016.05-tld-1.nsa310s.mtd0.kwb and uboot.2016.05-tld-1.environment.img.
I have modified the fw_env following the instructions (except I forgot to add the dtb_file variable).
Netconsole is working.

Last night booting from hard disk resulted in a red LED and today I try to boot from USB (Debian-4.4.0-kirkwood-tld-1-rootfs-bodhi).

* If I don't append the dtb file to the uImage, the result is a red LED (dtb_file set in /boot/uEnv.txt).
* if I do append the dtb file to the uImage, the result is a flashing green LED (dtb_file removed from /boot/uEnv.txt).

Either way, the nsa310s does not get a DHCP lease.
I notice that the rootfs filesystem on USB is modified (fcsk).

Following both netconsole output:and /boot/uEnv.txt

Please help me solve my boot problem,
Wilbert
