Pogo mobile nand bad block - installation failure

hello,

i am new to Linux but did read many topics in this forum and others.
after activating my new pogoplug mobile (v4-A1), i tried to install archlinux on it, using the instructions on ArchLinux site. i have encountered errors along the way. i have tried many steps to amend it, too many to recall.
current situation is that i am no longer able to connect to my home network. i am able to communicate with the unit with serial cable.
monitoring startup shows i have a bad block in the nand.
it can be seen here:
/ # dmesg | grep -i 'bad'
<6>[ 1.010000] Scanning device for bad blocks
<4>[ 1.020000] Bad eraseblock 157 at 0x0000013a0000
<5>[ 1.370000] UBI: number of bad PEBs: 1
<5>[ 1.410000] UBI: number of PEBs reserved for bad PEB handling: 8
/ #
and also:
/ # fw_printenv
Warning: Bad CRC, using default environment
bootcmd=bootp; setenv bootargs root=/dev/nfs nfsroot=${serverip}:${rootpath} ip=${ipaddr}:${m
bootdelay=5
baudrate=115200

i would like to get some help recovering the system; is it possible to re-install uBoot?
what should i do in order to amend the system and install Debian or Archlinux?

regards,

Eyal

E4691,

Boot up again with serial console, and get the entire serial boot log and post here. Looks like you can log into Linux with serial console, so please also post these info after you are in the shell:

uname -a
cat /proc/mtd
cat /etc/fw_env.config

Thanks for the fast respond.

the boot is done with a usb that includes re-installed Arch (based on re-installation instructions in ArchLinux.org). i can also boot without it (with same end result.
it is long, but here is the start log (with the last commands at the end):

OK, so you are not booting into Arch. It's in the stock Pogo OS. But also it seems the Arch installation was done unsuccesfully, but not because of the bad block 157 in NAND (it's far from the first 1M).

To recover, do the following:

1. Download the 3.16 rootfs from the Kirkwood rootfs thread (use Rootfs Debian-3.16.0-kirkwood-tld-2, Updated 02 Sept 2014). Put this on the USB drive per instruction.
http://forum.doozan.com/read.php?2,12096

2. Boot into Pogo OS like you did above.

3. Kill Pogo process:

killall hbwd

4. Mount the USB rootfs

5. Follow the instruction in the u-boot thread and install the latest u-boot for Pogo V4:
http://forum.doozan.com/read.php?3,12381

Note: the nandwrite and flash_erase utilities are already inside the USB rootfs so you don't need to download them:

/usr/sbin/nandwrite
/usr/sbin/flash_erase

6. After installing u-boot, you could reboot. And it will boot into Debian on USB. If you are not sure about you should reboot, please post the entire installation log here (including the creation of the rootfs) and I'll look it over.

Ok. i will have to do this later on (going to work now).
2 questions:

1. # cat /proc/mtd
gives a different data than what is specified, see here:

/ # 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"
/ #

it is OK that mtd0 is 00200000 00020000 "u-boot" (and not 00100000 ....) ?

2. / # nanddump -nf mtd0 /dev/mtd0
is answered with
mtd0: Read-only file system
how can i overcome this?

This is correct for the Pogo Mobile.

Dump to the USB drive. You were in the root directory (/). So if the USB was mounted as sda1 then

cd /media/sda1
/media/sda1/usr/sbin/nanddump -nf mtd0 /dev/mtd0

Hello bodhi

i did try to dump the nand to the usb, but with no success.
it seems that one of the issues of the bad system is it can not write or read to/from the usb. see here - end part of boot, finding the usb, my attempts to cd to it, and even fdisk p in order to see the partitions on the usb:

if i understand correctly, the nand dump is not a must.
And if this is the situation, how can i transfer the uBoot image to the nand? (meaning - how do i move the downloaded image to a directory were it can be found and extracted?)
any way you can think of in order amend it?

also
though it is stock pogo linux, i do have fw_printenv. nevertheless, ethaddr is not defined:
/ # fw_printenv
Warning: Bad CRC, using default environment
bootcmd=bootp; setenv bootargs root=/dev/nfs nfsroot=${serverip}:${rootpath} ip=${ipaddr}:${sem
bootdelay=5

/ #
anything to do with that?

Correct. If you can't do it then it's OK.

Do what I described above to prepare the USB rootfs using another Linux box (if you don't have one, then download Live CD to run on PC or Mac):
http://forum.doozan.com/read.php?3,21166,21172#msg-21172

Mount this USB rootfs on the Pogo so you can access it from there. Have you tried:

mkdir /tmp/sda1
mount /dev/sda1 /tmp/sda1

UPDATE:

And this is not good:

/dev/sda2 523 1021 3816704 83 Linux

Your USB drive contains other partition. You should reformat it a a single Ext3 partition and extract the rootfs to it per instruction.

bodhi,

i am trying to prepare the USB rootfs, with version 3.16.0. after extracting, i am stuck on step 4: there is no zImage file or /dts directory for correct DTB file name.

?

Eyal

just tried mounting the usb as you suggested - it works....
thanks.
what is the preferred path now - rootfs Debian or reflashing the nand?

The 3.16 rootfs is non-FDT so there is no DTB file. Each rootfs/kernel release has its own instruction. So when you use 3.16, you must follow the istruction in that section.

Look back the post above, I have laid out the steps above.
