PogoProReallyBrickedNow......

First I would like to thank all people like Bodhi en many more to provide means to keep legacy hardware up and running.

Unfortunately to keep it running is something more challenging.

After a lot of fiddling en trying I managed to have a working PogoplugPro (oxnas) booting from USB.
I had it installed with U-Boot 2013.10-tld-5 and Debian running.

In an attempt to update the uboot to 2015.10 I managed to really brick the pogo.
What went wrong?

I had ssh ´d into debian on the pogo and created some directories to manage the files. Copied uboot.2015.10-tld-2.ox820.bodhi.tar to it with scp from my desktop system. (I could not download it directly from dropbox with wget)

untarred it etc and entered the command to erase the MTD0 device (I assumed this is the SPL aera, but it does not matter anyway)
I got this output:

root@debian:/home/pogobackup/tmp# /usr/sbin/flash_erase /dev/mtd0 0x0 6
Erasing 128 Kibyte @ 7f623f5c00000064 --  6 % complete

Because the result did not show values that I would expect (...@0x and 100%) and because the memory area seemed way beyond 0x000000 I made the assumption that a reboot could be an option. ( I know Bodhi advised otherwise...)

How wrong appeared that assumption to be...................

There was no reboot. Only a dead Pogoplug. No Led, no serial, no nothing.

I am out of options now.

The only hope I have is that I may be able to boot from sata. Is that an option?

Or maybe revival using JTAG ?

Or should I accept that I really killed the device beyond revival......

The sata way is more or less described here: https://forum.doozan.com/read.php?2,32994
however I am lost at:

8b.) Run Sata uboot SCRIPT

./disk_create_shv

But before I will attempt all this I would like to know if the sata boot procedure, if implemented properly, would make a revival of the box possible.

I have been working with single board computers and electronics way long ago, so assume I could manage a JTAG recovery. However I have found no information about that with reference to the PogoPro system. Only de V4. And I assume that this procedure cannot be used as is for the PogoPro. And it is already bricked, no need to repeat it ;)

I have also noticed the mentioning of kwboot. But have no idea of that could do the job.

Hoping for the best.

Edit 1:

I have tried kwboot with the standard serial interface but got an error message because of image format incompatibility.

root@john-NUC6CAYH:/home/kwboot/kwboot-tool# ./kwboot -t -B 115200 /dev/ttyUSB0 -b uboot.spl.2013.10.ox820.850mhz.mtd0.img -p
uboot.spl.2013.10.ox820.850mhz.mtd0.img: Invalid image.

I assumed that the -p option would take care of the adjustment when using a standard image. But that assumption appeared to be false as well I guess.

At openwrt.org I read : https://openwrt.org/_export/xhtml/docs/techref/hardware/soc/soc.oxnas

 ..... kwboot-like serial recovery yet needs to be found…

So using kwboot to revive or program Oxnas devices seems undiscovered territory.

I have no idea of the detailed inner workings of kwboot. I have used X,Y and Z-modem protocols ages ago, know about hex S records for serial transfer to load ROM images to targets but that does not help me much now.
Maybe there is more needed then simple adjusting offset and is a more intelligent conversion needed from .img to .kwb format. More information is welcome.

Some further investigation about JTAG options seems to run into a dead end as well.

I have found general information about the chip used: NAS7820. The description matches the PogoPro functions and the information states that JTAG functionality is available on the chip.

I have scrutinized the PCB and found various scattered TPxx points on it but have no clue which function they have or where they are connect with.

The missing link appears to be how to connect a JTAG probe to the board. If that is even possible.... I also read that not all vendors have made JTAG functionality available. So it could be possible that JTAG support on the PogoPro ( I confirmed it is a Pro, because it has a miniPCI card for wireless) is not physically accessible. Or at best: not easy to find.

So my only hope left now is the sata boot. But before I try that I would like confirmation that it is a viable option.

Edit 2:
I found some info about JTAG and PogoPro:
looking at the PCB I saw a none installed header with 14 pins labeled HD5. A search for this :
https://archlinuxarm.org/forum/viewtopic.php?t=1640

2 things: the HD5 seems to be the JTAG header, but info about the pin layout is not available.....

The other thing is that it is indicated in the thread that sata boot might work.........
The latter however is not verified as far as I know.

to be continued?

I would gladly want to figure out the JTAG route. Even if that is more complicated.
So any info about the actual JTAG pinout would be appreciated.

hacksome,

It's a long post so let me know if I have not addressed any of your question!

This 6% is OK. The output was misleading on the latest flash_erase binary. It actually was successful.

You should have stopped here and post question :)

This box does not have kwboot capability. JTAG might be possible.

SATA is the sure way to unbrick this box. That's what make this box almost unbrickable. You don't even need NAND run it.

So try SATA and post the log of the session where you got stuck, or not sure about something.

Hello Bodhi,

thanks for your reply.

I now know ;)

I succesfully managed to revive the box using this procedure: https://forum.doozan.com/read.php?2,32994

I had to modify some things and have manually ¨created¨ the disk with only the perl part of the script and manually:
dd if=/home/sataboot/boot/u-boot-spl.bin of=/dev/sdb bs=512 seek=34

and I used: Debian-4.4.54-oxnas-tld-1-rootfs-bodhi.tar.bz2 instead the version because the version in the example is not available anymore.
I did not let it really boot into the disk and have interrupted the boot from the serial console

The first part boot showed:

It does no continue from here.

I guess I have to modify , add, delete some value´s with printenv.

But I have one question: I see consistently a leading bogus character in the first line printed from printenv.
It is not visible in the text on the forum.
It is this first line only, but maybe it has to do with the serial interface. However I have seen it before in earlier experiments and then it lead to error messages. ( I think) i have no idea how to erase it.


I tried tot rewrite the variable with: setenv dt_bootm bootm $uimage_addr $uinitrd_addr $dtb_addr<INTERRUP>
I did this because that text was literally shown on the serial terminal screen with printenv:

However that appeared false and is was not saved. A retry gave me this:

OX820 # setenv dt_bootm bootm $uimage_addr $uinitrd_addr $dtb_addr
OX820 # saveenv
Saving Environment to EXT4...
File System is consistent
file found deleting
update journal finished
File System is consistent
update journal finished
done
OX820 #

Then a reset again:

no change of variables with printenv still the bogus character appears on the first line and bootin does not continue.

But I am glad the box seems to be alive again. But I for now I take a break for a little while. It was a stupid mistake, to reboot after the nanderase.....

Maybe you have any suggestion where to find a proper example of env settings.

hacksome

Edit 1:
I coud not stand sitting idle without trying anything....
So i tried a few things:

I managed to change the environment after interrupting the boot:
I changes these settings:

dt_ide_bootcmd=run ide_set_bootargs; run dt_ide_boot
ide_set_bootargs=setenv bootargs root=/dev/sda1 rootfstype=ext4 console=ttyS0,115200 mem=128M

Now it boots in some kind of kernel initramfs.
see log:

I also tried to find out about weird characters in the first line preceding dt_bootm=... in the u-boot.env file in the \boot directory of the disk.
With a hex editor I saw a 5 byte header with the following hex bytes:

00000000 C1 CA 9D B8 16 64 74 5F 62 6F 74 6D 3D 62 6F 6F 74 6D .....dt_bootm

I was wondering if this is a corrupted file or maybe are those bytes there because of a specific file format of the u-boot.env file.

Also I am not sure if the 2 changes in the env setting I made had any influence because before I did that I also somtimes ended in the initram shell.

I assume that I have a mismatch between env settings and what images are to be loaded.

Unfortunately I have no clue what is related to what.

Maybe you can shine some light over it....

I forgot this information: when I take the disk (it is an SD card in a sata adapter) to another computer the disk is dirty and will not mount. When I fsck the disk all seems ok.

It's OK. From now we actually dont care about tthe current envs. We can load a latest set of envs and then boot directly into Debian rootfs.

That's still an old kernel.

All images in u-boot format has a header with checksum. In this case the envs image is read by u-boot and verified using this header.

That's normal. The HDD spare sector was written with the magic sequence. That might have caused some filesystem driver to assume that it is dirty.

Ok let me find the post with the envs script and show you how to populate the envs with a new set of values and then boot into a USB rootfs, or if you want, boot into the existing HDD rootfs that you have created.

hacksome,

I've realized that the script was a bit old. So let's modify the current envs so you can boot to Debian.

1. Debian rootfs

If you like not to touch the HDD so it can be used as a rescue mechanism, use a USB thunb drive to create the rootfs Debian-4.4.54-oxnas-tld-1-rootfs-bodhi.tar.bz2. Follow the instruction very closely (being root, single Ext3 partition, label it rootfs).

If you prefer to boot into the HDD rootfs you already created, then make sure that also was created properly ( (being root, label it rootfs).

And let me know that you are using which drive for rootfs.

2. At u-boot countdown, interrupt it and list your current envs

printenv

BusyBox v1.17.1 (Debian 1:1.17.1-8) built-in shell (ash)
but in an attempt to improve things I changed them.

I have a thumb disk I used as boot drive. When I remember it correct it meets your requirements:
label : rootfs
single Ext3 partition.
I am not 100% sure if it is Debian-4.4.54-oxnas-tld-1-rootfs-bodhi.tar.bz2. but I have onle a few other Debian archives downloaded on my system and I have not used the other ones. So it must be that version.
I inserted it in the front USB slot, (as I did before I bricked the box) but I have no indication that is was being accessed when I let the Pogo continue to boot. I ended up in the Busybox shell again.

BusyBox v1.17.1 (Debian 1:1.17.1-8) built-in shell (ash)

It looks as if nothing is mounted or not properly.

My intentions are to be able to boot from the thumb drive as before. I was in the process to prepare the system to reliably boot, had updated the Debian version (apt- update etc) and was thinking about to try to install OMV on it. But then things went awry.

I agree that having a rescue disk available is crucial. Maybe later I can decide I will use a sata drive as primary disk.
From what I read so far I assumed that with the latest Uboot version I can have all options:
Boot from sata when connected or boot from usb when connected. But I did not come that far:)
So at the moment my focus is: booting properly from the thumb drive again and then to configure the options I prefer.

By the way, I was also trying to establish netconsole communication but did nod succeed. I ended with the conclusion that the netconsole.ko module was not activated in the kernel of my desktop (ubuntu 18.04) . But then I put it aside for later because I have a serial link availble.
But that may be a thing to figure out when all is well again and booting and running properly......

Many thanks for your active assistance!

hacksome

hacksome,

Bring the SATA drive to another Linux box and change the partition label for the SATA rootfs to something other than rootfs (if it is currently rootfs). And then,

Boot with SATA like you did before, interrupt the u-boot countdown and

setenv usb_set_bootargs 'setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootdelay=10'
setenv bootcmd 'run dt_bootcmd_usb'
boot

And once it completes booting, you can see the Debian prompt. Log in with root/rootf credential and then you can flash new u-boot to NAND again permanently.


Remember that later, if you plug in this specially prepared HDD, it will boot into that system, always. Therefore, to attach an HDD, it must be a normal formatted one so it will not short circuit the USB rootfs booting.

Perfect!

Even the warning about the specially prepared disk. Initially I did not notice your warning properly.
I booted as you suggested. It did boot the kernel from the thumb drive. I SSH´d into the box. I flashed the new uboot (piece of cake because all the files were already on the thumb drive).

Then, without detaching the sata drive it rebooted but got stuck in a similar way (busybox shell) as before. Then I reread your warning.

Removed the rescue sata drive and it booted perfectly.

Thanks a bunch!

Maybe I can help fellow owners of this type of Pogoplug when I make a log if what I had done in order to ¨unbrick¨ a PogoPro.
I can also try to summarize how to start from a stock Pogopro (that was were I started) and then build one with the latest versions of u-boot etc.

I have spent much time figuring things out reading on this an other fora. With hindsight it is not that difficult at all. Of course there are many things in life that are similar, but when one´s goal is to use a Pogoplug (or similar) hardware for other purposes there is a rather steep trial and error curve involved if things described in various fora that are changed/updated now or not available anymore.

I don´t know why the created sata rescue disk on it´s own does not provide a usable kernel that makes flashing the nand possible. Maybe I can figure out a version that has those abilities.

I know that I need some assistance for that because I do not know (yet?) how the various env settings point to booting specific images and/or kernels etc.

But creating a basic SATA rescue with all tooling for nand management disk should not be that complicated I would assume. Only the proper env settings and the matching bootloaders etc?

Initially I will just describe what I have done so far. Even a slightly complicated way of working ( 2 stages) is better than nothing.

Anyway, many many thanks for your help!
It is nice to now that perfectly operating hardware can relatively easy get a life extension long after the commercial (read wasteful) suppliers have dropped support.

Keep up the good work! When and where I can I will try to add my part, as little as it is, but I suppose that is exactly the essence of how a community functions.

Thanks again,

hacksome,

It would be great to have. As your experience with this Pogo V3 unbricking told, we had enough instruction to do that from youxiaojie's thread. It could be improved (reorganized and some additions).

So please do that and I'll add yours (this) and youxiaojie's threads to the Wiki.

2 issues during your unbricking: the envs and the SATA rootfs. The envs need to boot the rootfs (2nd partition) on the rescue disk. The current envs out of the tarball by shv should be ok. But some how the rootfs was not mounted.

I was kind of trying to enhance (and understand the details) of youxiaojie's thread.
I was also wondering why the SATA disk did not boot properly.
And I think I found the problem, or at least part of it:

Also with the current (restored) Uboot in NAND when the the SATA disk (with the special code in the first sectors) is installed it will not boot properly. The log shows these lines:

[    2.489336] JBD2: Unrecognised features on journal
[    2.494179] EXT4-fs (sda1): error loading journal
mount: mounting /dev/sda1 on /root failed: Invalid argument

So I assume it does not mount because something is amiss with the features of the EXT4 filesystem. I disabled the feature using:

tune2fs -O ^has_journal /dev/sdb1

end then it booted properly from the SATA disk!

I am not sure if this behavior is caused by accident in creating or using the disk. Earlier logs showed automatic runs and repairs of the disk with fsck (sometimes using ext3, but also ext3).

Anyway, disabling the specific EXT4 feature resulted in a proper boot.
I wonder if using the EXT4 filesystem for a SATA rescue disk has advantages or might just cause troubles when things are not working smoothly. Maybe it is better to just use EXT3.
Is that correct?

Another minor thing: a relabeled the SATA disk to ¨rescue¨ because I also used a thumb drive labeled ¨rootfs¨ and at first boot from that kernel on the thumb drive I could restore the Uboot area.

But when the SATA drive boots properly there is no need for a thumb drive anymore.
When I interpret the logs I have from this configuration it even boots from a SATA drive not labeled ¨rootfs¨. There is only this complaint:

findfs: unable to resolve 'LABEL=rootfs'

But the systems boots into a maintenance kernel that can be used normally.
I have not verified if the maintenance kernel has all tools available for flashing NAND etc.

I am not quite sure if I interpret all information correct. But based upon this behavior I would say:
do not use EXT4 but stay with EXT3 filesystem.

I will still try to update youxiaojie's thread, but will also try to test some specific configurations for proper functioning. That may take additional time, but I hope that it will prevent others to get stuck.

Hacksome

Hacksome,

Yes, always use Ext3. The instructionn is quite old, and Ext4 file system behavior has been revised quite bit (e.g.lazy init,...) since then.

I have refreshed the procedure how to create a sata rescue disk. I have checked it only using an sata-SD adapter. It works with a Samsung EVO 32GB Sd and a 16Gb Kingston SD.

Steps to follow to create a sata rescue disk for a Pogo Pro or Pogo Classic.

You need a sata disk. All data on it will be destroyed.
A sata disk can be:
- regular sata disk 2.5 inch or 3.5 inch. However for the 3.5 inch disk you must have both 5 and 12V external power. For 2.5 inch disk you need only 5V.
- CF card or uSD card sata adapter: Both can be bought cheep at Aliexpress or ebay. (less then 10$)
- There are some drawbacks. Permanent use of SD card or CF card may be heavy for the memory card. But for a rescue disk it will be OK. No need for additional 12V power. 5V only is sufficient and can be taken from one of the USB ports of the Pogoplug if needed.
You can DIY this or buy an adapter cable (Aliexpress/Ebay)

Connect the sata disk to a linux box. You also can use your pogoplug as linux box.
If you do not have a direct sata connection available at your current linux box then a USB/sata adapter is very convenient. (Ali/Ebay...)

Open a root(!) terminal on your linux box: ( e.g. when in ubuntu ctrl+alt+t, then sudo -i and enter your password)
Mind that being root you can destroy your system when your command is wrong. (e.g. writing to the wrong drive or overwriting your existing system structures...)

If you connect the sata disk to your computer unmount it if it was automatically mounted when it was connected. (On my ubuntu box every time the drive is connected it became automatically mounted. Some operations described in the next part will not work on a mounted drive and will report an error. Other operations work without problem. Keep this in mind.)

Remove all existing partitions and create new ones using the fdisk command:
Fdisk commands/options:
i- show partition information
d- delete partitions
o- create a dos compatible empty partition table
p- create a new (p) primary partition (n) 1 starting at 2048 and specify a size with +2G (or larger)
w- write all changes to the disk
q- exit without writing the changes

Then format the disk (/dev/sdb1) as ext3 (ext4 is not recommended and may cause problems. ext3 is sufficient for a rescue disk)
Command: mkfs.ext3 /dev/sdb1
Optionally you can specify a label: immediately with the command: mkfs.ext3 -L rootfs /dev/sdb1

or separately modify the disk label with: tune2fs -L "rootfs" /dev/sdb1

Mount the drive with:
mount /dev/sdb1 /media/john/rootfs (on my system the drive is automatically mounted when inserted, so I use the names generated by the system)

Create a working directory: (mind! still all as root user!)
For example: /home/rescue
Extract ox820-sata-uboot.tar.gz to /home/rescue
You can do this in various ways:
- cd into /home/rescue and then tar -xvf /path_to_archive/ox820-sata-uboot.tar.gz .
- or from where the archive is: tar -xvf ox820-sata-uboot.tar.gz /home/rescue/
- or from somewhere else: tar -xvf /path_to_archive/ox820-sata-uboot.tar.gz /home/rescue/

After this a ./boot directory will be created in /home/rescue with the following content:

ls -l /home/rescue/boot
total 8380
drwxr-xr-x 2 root root    4096 aug  3  2014 dts
-rwxr-xr-x 1 root root   16384 jan  1  1970 u-boot.env
-rw-r--r-- 1 root root  525880 aug  3  2014 u-boot.img
-rwxr-xr-x 1 root root   32120 aug  3  2014 u-boot-spl.bin
-rw-r--r-- 1 root root 3676848 aug  3  2014 uImage
-rw-r--r-- 1 root root 2212156 aug  3  2014 uImage_2.6.31.14_OX820_1.2_shv.Pro
-rw-r--r-- 1 root root 2103272 aug  3  2014 uInitrd

Only if you have a pogo classic navigate to ./boot/dts and:
mv ox820-pogoplug-pro.dtb ox820-pogoplug-pro.dtb.ori
cp ox820-pogoplug-classic.dtb ox820-pogoplug-pro.dtb

Where can you find a ¨ox820-pogoplug-classic.dtb¨?
I found a ¨ox820-pogoplug-classic.dtb¨ in ¨linux-3.18.5-oxnas-tld-1.bodhi.tar.bz2¨archive. (I could not check the proper working because I have no Pogo Classic)

Skip all this when you have a PogoPro ( with miniPCI card equipped with wireless).

Copy the ./boot directory to the mounted disk.
cp -r ./boot /media/john/rootfs

To be able to boot from the SATA rescue disk it must be prepared in some special way:

First some special (¨magic¨) code must be written to the first physical sectors of the disk.
After that the SPL (Secondary Program Loader) u-boot-spl.bin is written to the disk.

This can be done with the following script:
¨disk_create.sh¨

#!/bin/sh

# uncomment line below and set to the correct disk
disk=/dev/sdb
#pay attention to fit yourself.this is  my situation

if [ -z "${disk}" ] ; then
   echo "You must uncomment/set the 'disk' variable"
   exit -1
fi

workarea=.

stage1File=$workarea/boot/u-boot-spl.bin

perl <<EOF | dd of="$disk" bs=512
    print "\x00" x 0x1a4;
    print "\x00\x5f\x01\x00";
    print "\x00\xdf\x00\x00";
    print "\x00\x80\x00\x00";
    print "\x00" x (0x1b0 -0x1a4 -12 );
    print "\x22\x80\x00\x00";
    print "\x22\x00\x00\x00";
    print "\x00\x80\x00\x00";
EOF

if [ -f $stage1File ];then
        echo "Writing stage 1"
        dd if=$stage1File    of="$disk" bs=512 seek=34
fi

You have to change the script to contain the correct variables such as the proper device name: most times it will be /dev/sdb
Also you have to execute the script from the directory you are in where the ¨u-boot-spl.bin¨ file is to be found or modify the line stage1File= so it will find the file.
To be able to have the script executed you have to chmod +x ¨script¨.

If you prefer you can partly do it manually:
Make a small script for only writing the ¨magic¨ code. (only the perl <<EOF .....EOF) part and manually execute:
dd if=./u-boot-spl.bin of=/dev/sdb bs=512 seek=34

After this preparation of the boot area of the disk you have to write the linux file system to the SATA drive:

I have used the current latest version for this: Debian-4.4.54-oxnas-tld-1-rootfs-bodhi.tar.bz2

Unpack the archive to a temporary directory on your system (all this still logged in as root (sudo -i)) to a working directory:

I have created a ´sataboot´ directory in my home directory with: mkdir /home/sataboot

cd /home/sataboot
tar -xjf /PathToArchive/Debian-4.4.54-oxnas-tld-1-rootfs-bodhi.tar.bz2

Then copy all files extracted form the archive to the mounted drive labeled ´rootfs´ directory, but DO NOT COPY the newly created ./boot directory!
Because then the sata boot images will be overwritten.....
You can manually copy all other directories one by one like this:

still from within /home/sataboot or cd to it:

cp -r ./xxx /media/john/rootfs
Where xxx is substituted with bin, usr, home, dev etc. but skip! the ./boot directory.

You can also move the ./boot directory elswhere, e.g. mv ./boot /home/tempboot/ and after that and from within the /home/sataboot directory copy al directories and files to the ´rootfs´ labeled sata drive with:
cp -r . /media/john/rootfs/


Then sync or unmount the drive
Connect it to your Pogoplug and boot it.
If no mistakes were made your Pogoplug should boot with Debian ( ssh password: root)

You can check the debian version after login with the uname -a command.

Have fun with you Pogoplug!

Good work :) There are a lot details in your writeup. Especially the part about how we would populate the rootfs.

If you don't mind, I will edit your post to organize the instruction a bit to make it easier to follow?

And I have a suggestion for a minor part that I will post later.

tar -xjf Debian-4.4.54-oxnas-tld-1-rootfs-bodhi.tar.bz2

Then copy all directories created to the drive root directory, but DO NOT COPY the newly created ./boot directory!
Because then the sata boot images will be overwritten
So manually copy all directories like this:

cd ????
cp -r ./xxx /media/john/rootfs
Where xxx is substituted with bin, usr, home, dev etc. but skip the ./boot directory.

You may also move the ./boot directory elswhere and then:

cd ????
cp -r ./DirWithAllDebianDirectoriesExeptBoot/. /media/john/rootfs/

This section is not clear enough! see above addition in bold. Basically, there should be a cd command to change directory where that tar should be executed. Likewise for the other 2 commands below. Don't describe them in text, if you could show exactly what commands to run.
