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?

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

 

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

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.
