Help with broken NSA325v2 (2 replies)

Hi there, a total u-boot noob here (have got experience in Linux),

I hope you are all doing well. I am hoping to get some help with my NSA325v2.

I had a NAS which wasn't booting, so I followed the guide on installing the new u-boot firmware, and managed to get a Debian usb to boot and work.

My problem seems to be that there is nothing on the NAND other than u-boot. I can't even flash to UBI!

When I got it, it seems like there is no partition table on the NAND (I am not sure if this is correct or not, it is an assumption). I assume this, because when I tried to follow the OpenWRT installation guide (https://openwrt.org/toh/zyxel/nsa310b). I skipped the step about flashing their u-boot, because I want to keep my u-boot (which I managed to flash by following (https://forum.doozan.com/read.php?3,12381).

So, some details:
- I got a debian USB up and running (the base version from September)
- I have U-boot 2017.07-tld-1 (Sep 05 2017 - 00:42:03 - 0700) installed
- I am currently connected via Serial using an RPI

When I follow the OpenWRT guide, I do the following, but get some undefined ubi error:

NSA325> nand erase.part ubi

NAND erase.part: incorrect device type in UBI

See attached all the debug information I thought might be useful:

Partition ubi not found!

If you need anything else, I'll happily provide anything you need.

I hope this is the correct place to write this!
