How to migrate from Debian to Arch Linux on PogoPlug series 4

I have a Pogoplug Series 4 (POGO-V4-A3-01) and boot from SD card, installed Debian version is :
Linux DebianPlug 3.18.5-kirkwood-tld-1

Now I want to change from Debian to Archlinux and I intend to follow this post:

Qiu's techNOLOGY Blog: Hacking Pogo Series 4 and Mobile

As my current pogo-v4 already installed uBoot, so I think I can start from "Debian/ALARM Installation on SD Card (or USB Hard/Flash Drive)",below are my planned steps:

1. prepare another new SD card

2. Insert this new SD card to a USB card reader and plug this USB card reader in current pogo-v4 (running Debian)

3. SSH connect to Pogo-v4 and input below command:

#stop my.pogoplug.com service (just in case)
killall hbwd

#Partition USB Flash
/sbin/fdisk /dev/sda

p # list current partitions
o # to delete all partitions
n # new partition
p # primary partition
1 (one) # first partition
<enter> # default start block
<enter> # default end block (to use the whole drive)
w # write new partition to disk

#download format utility
cd /tmp
wget http://archlinuxarm.org/os/pogoplug/mke2fs
chmod +x mke2fs

#format USB Flash
/tmp/mke2fs -L rootfs -j /dev/sda1

#create mount point
mkdir /tmp/mnt

#mount USB Flash
mount /dev/sda1 /tmp/mnt

#download Arch Linux ARM
cd /tmp/mnt
wget http://archlinuxarm.org/os/ArchLinuxARM-kirkwood-latest.tar.gz
tar -xzvf ArchLinuxARM-kirkwood-latest.tar.gz
rm ArchLinuxARM-kirkwood-latest.tar.gz

#Sync
sync
cd ..
umount /tmp/mnt

4. shutdown the pogo-v4, then unplug the USB card reader--> inject my old SD card (Debian system) --> insert the new SD Card with Arch Linux--> power on the pogo-v4

Can anybody have a look and give some suggestions if my plan works?

Thanks!

It depends which u-boot you have installed on this box. If it is one of my u-boot releases, then u-boot envs need to be modified to boot Arch.

I think that post is too old, so it is not up-to-date.

Do you have serial console and can post a serial bootlog with what you have currently running?

Unfortunately I do not have serial console and could not post the bootlog, any command that could show installed uBoot version?

Since the post is too old, highly appreciated if you could recommend one for reference.

Thanks!

Log into Debian and,

fw_printenv
grep -a --null-data U-Boot /dev/mtd0ro

Note that the 2nd command will spit out warnings in dmesg. So don't be alarmed when you see a whole bunch those error messages.

Without knowing the u-boot version, I can't say where you would get the instruction for the migration (other than I have to write it from scratch).

If your u-boot version is stock u-boot, then you should just use the Arch official instruction. This instruction will install Arch u-boot version for Pogo V4, and also prepare a new Arch rootfs:

Hello， Bodhi, please check the output when I typed 2 commands.

I just did what I planned last night. The new SD card inserted in USB card reader is listed as "sdb" as I type "fdisk -l", so I just changed to sdb/sdb1, then everything goes smoothly, finally the popoplug v4 successfully booted with Arch. The old version uBoot is great can suppport both Debian and Arch, sometimes it's really no necessary to update to the latest one.

I was using Debian for couple of years. Due to a power surge it crashed. Now i thought of installing arch linux in a new USB on my Pogoplug V4.

Currently i tried loading the archlinux to a USB but its not booting.

I have 2015 Boot Version, Should i need to do any additional changes?.

Thank you Bodhi. Would like to whether Uboot 2016 version able to boot Debian with EXT4 ?
