Zyxel NSA325 - Installing ALARM on flash drive

[Siron]

Hello.
I have insalled the OS as described on the HDD in the left slot. Now I was wondering if it would be possible to copy this installation on an USB flash drive and set a variable in U-Boot to boot from that flash drive.

Can you guys tell me if this is possible and if yes give me a short instruction how to do so? With what partitions and what filesystems does the flash drive need to be prepared?

Many thanks for your effort!

So I was trying to install it. I partitioned a flash drive like the script "usb_key_func.sh.2" did partition my hdd in the left slot. I then was using mkfs.ext2 on partition 1 and mkfs.ext4 on partition 2 for the file systems. After that I copied "uImage" to "boot" and "rootfs" to "rootfs".

So I think the flash drive would be ready to go.
Next I tried to remove my hard drive and plugged in my flash drive on the rear usb 1. My problem is that the NSA reboots every few seconds even if I interrupt U-Boot with a keypress. Does anybody know how to prevent these reboots?

Many thanks.
