Question about updating Uboot for a PogoPlug V3 classic Oxnas (OX820)
April 28, 2020 01:28PM
Hi Bodhi,

I have another PogoPlug V3 circa 2012 that unfortunately do not have a running system and I would like to update it to newer Uboot to use your Debian rootfs, since I understand that your newer rootfs requires newer Uboot.

What is the best way to achieve this without a serial cable? I was looking for Debian-3.xx rootfs on your dropbox but it appears to be gone.

Thanks in advance for your help.

Do you recall how it was set up to run in 2012? was it ALARM installation? If I know what you did back then, I could potentially show you how to boot with an old Debian rootfs.

There are a few alternatives.

- Boot old Debian rootfs by guessing what envs are currently in u-boot.
- Boot with a SATA drive, specifically prepared to by pass u-boot on NAND. This requires openning the box and connect a SATA cable to an outside bare disk or eSATA enclosure.
- Connect serial console (easy, no soldering needed).

Bodhi,

As always I really do appreciate your quick response and help.

I have two units, and it looks like back then I 'hacked' them both to boot from a SATA hard drive (via a SATA cable) to run ALARM. One unit boots and I was able to install your new uBoot after booting into ALARM and now have Debian running. The other also has a SATA hard drive connected via a SATA cable but it refuses to boot, the LED keeps flashing.

I was hoping to be able to do this with your old Debian rootfs.

I think this hardware set up is already done, I have a SATA cable connected to an outside hard drive.

I remember did build a serial cable, but could not locate it at the moment. I guess this would be the last resort.

Thanks,

nnSlick,

To recreate the SATA hack drive is more time consuming.

So I will try to restore the post's part for older rootfs (should be in my saved release notes).

I've hijacked the 2nd post in the release thread to make it an older releases post. You can find rootfs 3.x in there.

Bodhi,

Wow, appreciate your prompt response!

The link to Debian-3.17 rootfs on Dropbox seems to be expired though, as I get a 404 error trying to download it.

Turned out I've removed that file to gain back some Dropbox space when it ran low. I've re-uploaded it just now.

Rootfs Debian-3.17.0-oxnas-tld-1-rootfs-bodhi.tar.bz2 was uploaded. This rootfs is to keep in sync with kernel Linux-3.17.0-oxnas-tld-1.

Basic minimal Debian Oxnas rootfs for Popo Pro/Classic V3 plug:

- tarball size: 83M
- install size: 251M
- a basic wheezy rootfs
- Installed packages: nano, avahi, ntp, busybox-syslogd (log to RAM), htop, dialog, bz2.
- see LED controls in /etc/rc.local, and /etc/rc0.d/K08halt
- see some useful aliases in /root/.profile
- root password: root

Bodhi,

Thanks for the link and for re-uploading the old rootfs. I downloaded it and try but the plug does not boot.

Since I have another unit working I will put the this one in the garage and will try to revive it with a serial cable.

You are awesome and I really do appreciate your help.

Thanks,
nnSlick.

In case you want to give one more shot.

I forgot that you were booting Arch with stock u-boot circa 2012. So the the Debian rootfs needs to have uImage with DTB appended (Step 4). It cannot be used as is, out of the box.

My pleasure!

Hello,

I have a similar problem like the original poster. bought an old pogo pro who previously seems to boot with arch, but keep original u-boot. Envs look like a mess. Is it possible to boot debian rootfs 4.4.54 by changing the envs on original uboot or must i try to create an arch usb stick? Log was created with latest rootfs on the usb stick

Re: Question about updating Uboot for a PogoPlug V3 classic Oxnas (OX820)

Envs look like a mess

It is a big mess. And currently it always boots to stock OS.

So if you have not created the USB rootfs, then do so using Debian-4.14.180-oxnas-tld-1-rootfs-bodhi.tar.bz2

However, since you are booting with stock u-boot, the uImage in the rootfs must be appended with the DTB file /boot/dts/ox820-pogoplug-pro.dtb.

So on the Linux host that you use to create the USB rootfs, after you untar the rootfs tarball to the USB drive (assuming the USB drive is mounted as /media/sdb1):

cd /media/sdb1/boot
cp -a uImage uImage.orig
cp -a zImage-4.14.180-oxnas-tld-1  zImage.fdt
cat dts/ox820-pogoplug-pro.dtb >> zImage.fdt
mkimage  -A arm -O linux -C none -T kernel -a 0x60008000 -e 0x60008000 -n Linux-4.14.180-oxnas-tld-1 -d zImage.fdt uImage
sync
Umount the USB drive. Bring it back to the Pogo Pro.

And then post back here, I'll show you how to change envs to boot this Debian rootfs.

Bodhi, thanks for your help.
I was able to get the new uboot to the pogo using the tffp method.

But unfortunatly Debian is not booting. I installed OpenWRT in Nand, which boots fine. I installed the rootfs to 3 different USB Sticks, but non of them works:

Cool! that looks excellent.

Now, since you are booting with the new u-boot, the uImage must be the original (becasue the DTB is loaded separately)

So this step should not be done:

cd /media/sdb1/boot
cp -a uImage uImage.orig
cp -a zImage-4.14.180-oxnas-tld-1  zImage.fdt
cat dts/ox820-pogoplug-pro.dtb >> zImage.fdt
mkimage  -A arm -O linux -C none -T kernel -a 0x60008000 -e 0x60008000 -n Linux-4.14.180-oxnas-tld-1 -d zImage.fdt uImage
sync

Mount the USB rootfs on another Linux box and reverve the uImage to original.

cp -a uImage uImage.fdt
cp -a uImage.orig uImage
sync

And then it should boot fine and mount the rootfs sucessfully.

Works perfect, thanks Bodhi!

Just didn't read your instructions in the debian thread careful enough.
