[Question] How to install Debian on PogoPlug POGO-V4-A3-01 which is currently running Archlinux ARM? (no replies)

Hi I have a PogoPlug POGO-V4-A3-01, and I have installed Archlinux ARM on it using this tutorial:

https://archlinuxarm.org/platforms/armv5/pogoplug-series-4

So I want to run this Debian on it:
https://forum.doozan.com/read.php?2,12096
I downloaded this rootfs pack: Latest released rootfs: Debian-5.2.9-kirkwood-tld-1-rootfs-bodhi.tar.bz2 (25 Aug 2019)
I did not use the latest kernel.
I prepared a SD card with that rootfs package (filesystem is ext3 with journaling)

I downloaded this latest U-Boot:
https://forum.doozan.com/read.php?3,12381

I followed this UART boot guide:
https://forum.doozan.com/read.php?3,7852,7852

And I successfully booted into U-Boot with prompt "Pogov4".
I remembered I have to chagne this environment var from:

dtb_file=/boot/dts/kirkwood-pogoplug_v4

To:

dtb_file=/boot/dts/kirkwood-pogoplug_v4.dtb

And the devices starts running Debian now.

So the next step I reckon is to write the U-boot to somewhere in the internal "mtdblock". And I suppose the environment variables to U-Boot need to be updated as well?

In current Debian system, my configuration is as follows:
Are they correct?

# cat /etc/fw_env.config
# MTD device name       Device offset   Env. size       Flash sector size       Number of sectors
/dev/mtd0 0xc0000 0x20000 0x20000
root@debian: /dev
# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00200000 00020000 "u-boot"
mtd1: 00300000 00020000 "uImage"
mtd2: 00300000 00020000 "uImage2"
mtd3: 00800000 00020000 "failsafe"
mtd4: 07000000 00020000 "root"

Do I need to change /etc/fw_env.config to the following?

mtd0: 00100000 00020000 "u-boot"

I've seen this error on console for env vars:

# fw_printenv ethaddr
Warning: Bad CRC, using default environment
ethaddr=00:00:11:22:33:44

There may be no need to backup these environment variables in Debian?
Or do I need to boot to the Archlinux U-boot and save output from "printenv"?


So in this running Debian system, I just need to run the following commands?

flash_erase /dev/mtd0 0 4
nandwrite /dev/mtd0 uboot.2017.07-tld-1.pogo_v4.mtd0.kwb

And flash default u-boot envs:

/usr/sbin/flash_erase /dev/mtd0 0xc0000 1
/usr/sbin/nandwrite -s 786432 /dev/mtd0 uboot.2016.05-tld-1.environment.img

And finally update environment vars:

fw_setenv arcNumber 3960
fw_setenv machid f78
fw_setenv mtdparts 'xxxxxxxxx'

(This "mtdparts" var has the following value when I UART booted the U-boot, is it correct?
mtdparts=mtdparts=orion_nand:2M(u-boot),3M(uImage),3M(uImage2),8M(failsafe),112M(root)
)

fw_setenv ethaddr 'xx:xx:xx:xx:xx:xx'
fw_setenv dtb_file '/boot/dts/kirkwood-pogoplug_v4.dtb'

And also the env vars for utilizing "uEnv.txt".
Is this all?
Thank you.
