if anyone's interested.

I made some progress with booting Armbian from USB on my Mochabin. I've been teaching myself U-boot cli.

 

I downloaded Armbian_community_24.5.0-trunk.93_Espressobin_jammy_current_5.15.149.img.xz and used dd to write it to a USB stick.

Marvell>> usb dev

            Type: Removable Hard Disk
            Capacity: 29604.0 MB = 28.9 GB (60628992 x 512)


Marvell>> usb part

Then to boot from the USB I use:

setenv bootargs 'console=ttyS0,115200' 'earlycon=uart8250,mmio32,0xf0512000' 'root=/dev/sdb1' 'rootfstype=ext2' rootwait

setenv bootcmd 'true; usb start; ext2load usb 0:1 $kernel_addr_r $image_name; ext2load usb 0:1 $fdt_addr_r boot/dtb/marvell/armada-7040-db.dtb; booti $kernel_addr_r - $fdt_addr_r'

boot

 

The image boots but the kernel reports that it is waiting for /dev/sdb1

 

What should:

root=

be set to, please?

 

Thanks,

Butch

I put all the console output in this gist:

In general I would expect the root parameter to look like:

root=UUID=997635c3-00f2-4eca-aa3d-1bf187651ea3

or

root=LABEL=armbi_root

(obviously with the correct LABEL or UUID for your root partition)

Why did you repost the log?  Have you changed your root= parameter as was suggested?

[Butch Driver]

Yes, I said that I used a number of different root=

 

I reposted what I think is the most important part of the log.

[Butch Driver]

My next step is to get Kevin's and Lynix's kernel config files off of Github and compare it to what's in the build system.

But the root= in the log file is wrong.
