Backup and Restore NAND mtds - Pogoplug V4 original MTD partitions

Since a lot of people have been getting the Pogo V4/Mobile lately, just thought I'd repost the download link to one of my Pogo V4s original MTDs here. In case anybody wants to revert to stock, and can't do it because they have already installed newer U-Boot.

Dowload at Dropbox:
pogoplug_v4_mtd_original.tar.bz2
md5
064a298c89ae5a1b207061e11b401930

You only need to use mtd0 to restore u-boot. And that's enough to go back to stock. Other mtds are included in the tarball just in case the whole NAND needs to be restored :)

And if you use these mtd partitions to restore, please remember to reset the cesvcid to your own number :), and also reset ethaddr to your own box, so that you can continue using Pogoplug service. The environment variable looks like this:

cesvcid=V88XBRRLWPC9WYGQxxxxxxxxx

A. How to restore NAND in Linux (any distro):
====================================

Warning: Don't do this if you have any bad block in these MTD partitions, especially mtd0 (check your dmesg). And also do this at your own risk, it's highly recommended that you have serial console attached to recover from any bad flash.

The original mtd0 was saved using the following nanddump command:

/tmp # ./nanddump -nf usb/mtd0 /dev/mtd0
Block size 131072, page size 2048, OOB size 64
Dumping data starting at 0x00000000 and ending at 0x00200000...

So in order to restore mtd0 back, you can use flash_erase and nandwrite. Below are actual flashing and output. Your output should look exactly like these. If not, don't reboot, and post the question here.

1. make sure the mtparts are correct

# fw_printenv mtdparts
mtdparts=mtdparts=orion_nand:2M(u-boot),3M(uImage),3M(uImage2),8M(failsafe),112M(root)

2. Erase mtd0:

#flash_erase /dev/mtd0 0 16
Erase Total 16 Units
Performing Flash Erase of length 131072 at offset 0x1e0000 done

3. Write mtd0 backup file back to NAND:

# nandwrite -on /dev/mtd0 mtd0
Writing data to block 0 at offset 0x0
Writing data to block 1 at offset 0x20000
Writing data to block 2 at offset 0x40000
Writing data to block 3 at offset 0x60000
Writing data to block 4 at offset 0x80000
Writing data to block 5 at offset 0xa0000
Writing data to block 6 at offset 0xc0000
Writing data to block 7 at offset 0xe0000
Writing data to block 8 at offset 0x100000
Writing data to block 9 at offset 0x120000
Writing data to block 10 at offset 0x140000
Writing data to block 11 at offset 0x160000
Writing data to block 12 at offset 0x180000
Writing data to block 13 at offset 0x1a0000
Writing data to block 14 at offset 0x1c0000
Writing data to block 15 at offset 0x1e0000

If you need to restore mtd1 to mtd4, then calculate the number of blocks for each mtd (i.e. a block is 128K, 1M is 8 blocks).

NOTE:

The nanddump command above is to back up your own box and later restore it to the same box. To backup mtd0 (or other mtds), make it a little more robust so that it can be used in different boxes without problem (thanks restamp for suggestion), use the following format:

nanddump --noecc --omitoob -l 0x80000 -f mtd0 /dev/mtd0

B. How to restore NAND in Serial Console:
==================================


Here is what to do if you've decided that you need to restore NAND mtd0 in serial console to go back to stock OS. Assuming only mtd0 was messed up (that's how it usually happens). If the entire NAND was messed up, then use this procedure to restore mtd0 and then calculate the offset and size of the rest of the other mtds. If you're not sure, pls post questions in this thread.

Caveats: This is something I would not recommend doing, unless you can no loger boot into Debian or Arch. Because If you can use kwboot to boot the box, then you can boot Debian or Arch quite easily, without doing this procedure. See the Debian kernel/rootfs thread for how to create the Debian 4.4 rootfs to use with this box.

The procedure below has a lot more risk of errors occurred than flashing NAND mtd0 from Linux command line (section A).

Prerequisites

r1. This procedure requires a working serial console connected to the Pogo V4. And knowledge how to use kwboot to boot the latest version of u-boot.

r2. Download the latest u-boot, and kwboot binary as described in the u-boot thread to the serial console server (where you run kwboot). Create a single partition, type Ext3, USB thumbdrive. Copy your backup mtd0 to this USB drive root folder. Plug this USB drive into the Pogo V4 top USB port.

Restore NAND mtd0

1. Connect serial console and use kwboot to boot the Pogo V4. See davygravy instruction for more details. I'm assume that you already know how to use kwboot.

Run kwboot and interrupt serial console when you see the countdown:

./kwboot  -t -B 115200 /dev/ttyUSB0 -b uboot.2016.05-tld-1.pogo_v4.mtd0.kwb  -p

Expected output

4. Load the backup mtd0. Here the stock mtd0 backup file name was mtd0.pogo_v4

ext2load usb 0:1 0x800000 /mtd0.pogo_v4

Expected output

2097152 bytes read in 1318 ms (1.5 MiB/s)

5. Erase mtd0

nand erase 0x0 0x200000

Expected output

NAND erase: device 0 offset 0x0, size 0x200000
Erasing at 0x1e0000 -- 100% complete.
OK

6. Flash mtd0.pogo_v4 to NAND mtd0

nand write 0x800000 0x0 0x200000

Expected output

NAND write: device 0 offset 0x0, size 0x200000
 2097152 bytes written: OK

7. Reset the box to boot with stock u-boot

reset

Expected output:

The stock u-boot banner and other info. And then it will proceeed to boot stock OS.

DONE.

Thanks for posting this.

Can you clarify if this is for the Pogoplug Series 4 or Mobile or does it even matter?

Also, what are the instructions for restoring the various mtd partitions back? Thanks

I think it's the same for V4 or Mobile (you would have to try to confirm, no guarantee though). Except that your ceboardver environment variable should be the correct one. Here is the Pogo V4 ceboardver:

ceboardver=PPV4A3

I've added flashing instruction in the 1st post.

Hello,
a friend of mine gave me a bricked Pogoplug v4, in which manner I could not understand.
So I put a serial port on it and tried this tutorial to revert it to original, since USB thumb method doesn't work.
Serial access is OK, but i' m stuck at step 1.
When I type fw_printenv mtdparts, I get -/bin/sh: fw_printenv: not found.
I tried that on preboot (CE) also, and got the same response..

Any idea? Thank you

Danilo,

If you booted with serial console, and gained access to the Linux prompt, then it must be the Pogo OS. If you're not sure, post the output of

uname -a

or post the entire output of:

dmesg

In Pogo OS, fw_printenv is not available, the command to list envs is: blparam. It's in one of the sub directories under /usr/local/sbin/cloudengines or /usr/local/bin/cloudengines. Be careful, don't execute it with any parameter, just blparam to list the envs:

For example:

/usr/sbin/cloudengines/bin/blparam

Does this mean I cannot use the restore? is there another way?
It is not bricked, just want factory restore.

rlimas,

> It is not bricked, just want factory restore.

The bad blocks are not in mtd0. So you could restore mtd0, which is all you need to do. When you install newer u-boot, only mtd0 was written.

Before you do this, I would strongly recommend connecting connecting serial console, or only if you would be willing to connecting one should anything goes wrong.

Hello bodhi

Could you plz help me double check the commands below?

Erase mtd1:
#flash_erase /dev/mtd1 0 24 ( All mtd device's start address is "0" ?)

Erase mtd2:
#flash_erase /dev/mtd2 0 24

Erase mtd3:
#flash_erase /dev/mtd3 0 64

Erase mtd4:
#flash_erase /dev/mtd4 0 896

==============================================================
My problem is my pogo v4 series it maybe flashed firmware of pogo v4mobile before, so now it can't load sata HDD,
I now wanna the function of sata hdd, shall i reflash all from mtd0 to mtd4?

/tmp # cat /proc/mtd
dev: size erasesize name

===============================

it seems that mtd4 is 70M, not 112M, anything wrong?

No need to. When you install u-boot, only mtd0 was written. However, are you booting this to Debian or Arch? if you can boot this Pogo V4, then you only need to install new u-boot from this thread:
http://forum.doozan.com/read.php?3,12381

Quote

mtd4: 07000000 00020000 "root"

This is OK. It's 0x07000000 in hex.

If you'd like to confirm before installing new u-boot, post your dmesg log here, and also post your currently installed u-boot version here too.

Hello bodhi
Thanks your helping!

1) my pogo v4 series is second hand for me ,and i am not good at Linux, so i don't know where to confirm my currently installed u-boot version, and dmesg log's location. would you plz give me a guidance?

2)few days ago, i have downloaded attached files above:pogoplug_v4_mtd_original.tar.bz2 . and I unrar it in win7, then i have restore the original mtd0 to my pogo,but after that my pogo v4 still cannot load sata hdd.

3)i have read topic ' 2014.07 U-Boot Kirkwood '.
there question.
Erase mtd0
flash_erase /dev/mtd0 0 4
In this topic :flash_erase /dev/mtd0 0 16. Should I used “4” or "16" blocks?

thank you very much~~

Boot the Pogo. Log into Debian, at the command line , execute:

dmesg

Capture the output and post here.

The old u-boot can't boot SATA. You need to install new-u-boot. The backup mtd above is the original MTD, i.e. stock .

They are 2 different procedures.

Quote

> flash_erase /dev/mtd0 0 4

Erase 4 blocks (512K) to flash u-boot, which is 512K.

Quote

> In this topic :flash_erase /dev/mtd0 0 16

Erase 16 blocks (2M) to flash the orginal mtd0, which is 2M.

Hello bodhi

I have posted dmesg above, plz give me help with your convinience. Thanks!

Ryan,

> ~ # blparam > current_envs.txt

You are running stock OS. So blparam is at /usr/local/cloudengines/bin/

/usr/local/cloudengines/bin/blparam > current_envs.txt

And you have no bad blocks. It is safe to flash new u-boot.

But serial console is highly recommended, if you can, connect it first.

Ryan,

Let me see if I understood you correctly: the USB rootfs works fine, and now you are looking for a way to boot stock OS?

Hello bodhi

First I registered the pogo on website my.pogoplug.com , and when i insert a HDD in SATA SLOT, i can't find the hdd disk in my.pogoplug.com, but usb disk is ok. so i thought it must be the firmware is mistake, so i want to reflash mtd0 . After flshing mtd0 of your original one , it still cannot find sata HDD in my.pogoplug.com. And so i upgrade the 2014.07 U-Boot . After that cannot boot correctly,green led flashing always.

I don't know how to boot usb rootfs, so i don't know whether it is fine.

I wanna boot stock OS and wanna find the HDD[ SATA SLOT] in my.pogoplug.com.

I am sorry that bothering you so much, but hope your help too.

thanks~!

Ryan,

The best way to boot stock and use pogoplug.com is to restore mtd0 using my backup. And you also need to adjust the cesvcid like I described in the first post. And reboot. After that if pogoplug.com finds your plug, then it should see the HDD.

BTW, are you also aware that pogoplug.com needs a paid subscription to use?

So the bottom line is if you want to use pogoplug.com , don't install new u-boot. There is a way to use new u-boot and boot stock OS, but it is not simple to set up.

I would avoid restore mtd using serial console. So if you can do it in Linux, then it would be best.

You could install Debian rootfs 3.16 on USB:

Boot into Debian and go from there.

It seems your rootfs was not created correctly. Try following the instruction to create 3.16 rootfs again. You can post the entire log of how you do this here, perhaps you missed a certain step or some importan tinstruction?

hello bodhi

Procedure below:

1）I used ParagonPartitionManager V12 to make Ext3 partition in the USB DISK.

2) plug this usb disk into the front panel of POGO-E02.(with openwrt)

3) under win7 I run Xshell to connect a POGO-E02 with openwrt via SSH.

4) then entry the LINUX OPENWRT and use command in XSHELL:
cd /mnt/sdb1
tar -xjf Debian-3.18.5-kirkwood-tld-1-rootfs-bodhi.tar.bz2
it tell me error "j" is not optional.

so use "tar -xf Debian-3.18.5-kirkwood-tld-1-rootfs-bodhi.tar.bz2"
it tell me error "invalid tar magic"

5) because cannot tar the file. I extract it in win7 with WINRAR.

6) after extracting, I entry the folder /mnt/sdb1 via FTP.

7) upload the files extracted moment ago by FTP. after that I think I finish the USB disk installing.
