Booting Arch with u-boot-2015.10-tld-1

Hi. Need a little help here.
I`ve followed the guide to install the 2015.10 uBoot on Pogo E02 and prepared the USB stick with unpacking Debian-4.4.0-kirkwood-tld-1-rootfs-bodhi.tar.bz2 on it. Looking at the netconsole output the kernel is found buy the Pogo box but it doesn`t get assigned an IP so no way of pocking inside and see what went wrong.

Starting kernel ...

sunspot,

Netconsole only outputs this much. After the kernel begins starting, there will be no more outptut, unless Debian was setup to output more during kernel booting. And this requires the initrd image to be regenerated while Debian is running.

Try interrupting netconsole to print out the u-boot envs. Assuming the Pogo u-boot env ipaddr was set as 192.168.0.100, use this command:

nc -lup 6666 192.168.0.100 6666

Other things to check to make sure you have created the rootfs correctly:

- you were root user during the creation of the rootfs.
- the rootfs USB drive contains one and only one partition type Ext3
- the partition is labeled as rootfs

A little backstory: was initially running Linux-4.4.1-1-ARCH as per Jeff instructions, then decided to upgrade to new uBoot and found out the hard way that your uBoot somehow didn`t like ARCH. So in order to boot the box and flash moonman`s uBoot I`ve switched to Debian on USB stick.

So I should probably run something like

sudo chown root:root /

on some Linux machine, right?

Anyway this is what I have

sunspot,

You must be the rootf user while extracting the rootfs tarball. Either log in as root, or use su command to become root. If you only want to boot any Linux to reflash u-boot then that's it! follow the installation instruction very closely and it will boot Debian rootfs without changing u-boot envs.

OTOH, If you you want to boot Arch from my u-boot image, then set the DTB file path to the location of the DTB in Arch rootfs, and not using label, then it will boot Arch. Do it in netconsole:

setenv set_bootargs 'setenv bootargs console=ttyS0,115200 root=/dev/sda1 rootdelay=10 $mtdparts $custom_params'
setenv dtb_file /'boot/dtbs/kirkwood-pogo_e02.dtb'

I`ve rechecked the USB stick under Oracle VM running Ubuntu. For some reason I couldn't paste the console output through the clipboard hence the screenshot.
My ARCH installation is lost, somehow my USB stick become corrupted after doing USB->image backup under windows, e2fsck showed tons of errors.
So I`ve reformatted the whole thing from scratch and now am trying to boot Ubuntu on Pogo E02.

There are a couple things wrong in the screenshot you've posted.

- You were not root.
- Your rootfs label is ROOTFS. Remember in Linux everything is case-sensitive. It must be rootfs.

Please follow the instruction exactly as it was written.
