i try to start Amibian from USB-Stick on a Raspberry Pi 3b+. I changed the the command root=/dev/mmcblk0p2 to root=/dev/sda2 from cmdline.txt.
If i now try to boot from usb-stick then i get the bootpic and then it hangs up.
If i press "enter" on keyboard then i get the message:
map: vt01 => fd0
and nothing happens anymore.
What do i change to get Amibian start from an usb-stick?
