Pi4, boot from usb SSD

[thegreatnothing]

Hello dears,
today I'm trying to boot my Pi4 (ubuntu arm64 server) from ssd.
Let me explain the partitions:

microsd cards:
- boot
- data
ssd (usb):
- data (exact copy of microsd data)

boot changes:
In boot microsd partition (not folder) I changed the nobtcmd.txt the root parameter adding the partition id like root=PARTUUID=da84cd12-01 (that is ssd data partition id)

But when I restart the raspberry I can't connect anymore to ssh. What's wrong for you?

I figure it out how to do it, and made a short guide to everyone who would like to do the same thing. Here is my guide https://krdesigns.com/articles/raspberr ... -SSD-drive Hope this will help...
