NSA325v2 Debian rootfs (1 reply)

So I've decided to dust off this NAS after 5 years and try this again, but I'm a dummy and got overwhelmed by the instructions.

I have a working serial connection and can successfully log in from Ubuntu using

kwboot -t -B 115200 /dev/ttyUSB0 -b uboot.2017.07-tld-1.nsa325.mtd0.kwb -p

and run commands, but I'm not sure where to go from there to flash latest uboot and get Debian on it.

I started at the 25 Aug 2019 section in this guide but I don't understand step 5. How do I boot into Debian with the prepared USB stick? Just plugging it to one of the USB2 ports and powering up doesn't seem to do anything different.
