[SOLVED] Uboot boots from wrong disk

[hachel]

Hi,

I have my raspberry 4 set up to boot from USB. This works great, but since I've connected a second USB disk it always boots from that.

The setup is as follows:

/dev/sda
.../dev/sda1 - /home/...

/dev/sdb
... /dev/sdb1 - /boot
... /dev/sdb2 - /

I want it to boot from /dev/sdb1 but it naturally always boots from /dev/sda1. A workaround is booting with just "sdb" connected and then plugging in the data disk after a few seconds, but that needs me to be physically present.

I tried changing the uuid in the boot.txt but I'm not sure where (first line below or second) and how.
[code]
part uuid ${devtype} ${devnum}:2 uuid
setenv bootargs console=tty1 root=PARTUUID=${uuid} rw rootwait smsc95xx.macaddr="${usbethaddr}"[/code]
Any help would be appreciated!

Hi, i solved it. For future reference:

I changed PARTUUID=${uuid} to PARTUUID=745a7... (it's partuuid).
