Bodhi,

I'm curious as to what the optimal way to update my pogoplus is? I think I need to update everything, including uboot, kernal and Debian.

Thanks, Wes

Your kernel is the latest now. So only the rootfs needs to be
apt-get update
apt-get upgrade

Your u-boot is not too old, but since you have serial console, you can recover from any problem in installing u-boot if you would make sure to try UART booting before installing new u-boot u-boot-2016.05: http://forum.doozan.com/read.php?3,12381

In the u-boot installation instruction:
Quote

Important Note: If possible, try to test this boot image with UART booting before flashing to NAND. See davygravy's UART booting using kwboot instruction here in this thread. The latest u-boot image released here should be used for UART booting, if your box is the type that supports it (these do not: Dockstar, Pogo E02, iConnect).

Bodhi,

I think I just bricked it, and It's all my fault for not wanting to ask anymore questions. I got an error on this part of the 2016.05 u-boot install "/usr/sbin/nandwrite -s 786432 /dev/mtd0 uboot.2016.05-tld-1.environment.img" and like a tired idiot decided rebooting would get me through it.

Here is the pastebin with my history and the error booting near the bottom. I'm going to get some rest for now, and try to learn more a different time. Thanks for all the help along the way though. Pastebin: http://pastebin.com/5ZHQ1p00

Hi Wes,

It happens to all of us, yours truly included :)

Recovering from this is not hard. You have not bricked it at all! You have flashed the new u-boot successfully. But now your envs are all messed up (because of the error while flashing that).

Now it's time to use the uEnv.txt to boot. This file will be read by u-boot during boot phase, and whatever envs in there will be used to overwrite what's in memory.

Booting with uEnv.txt:

- Plug in your Debian rootfs to another Linux box. I am assuming that you have Ubuntu or another Linux Desktop/Laptop or can boot with Linux Live CD.

- Mount it and go to the boot folder.I assume it was assigned the drive letter sdb1.

mount /dev/sdb1 /media/sdb1
cd /media/sdb1/boot


- Copy the env text file in the new u-boot tarball that you have downloaded before.

cp -a uboot.2016.05-tld-1.environment uEnv.txt


- modify the envs in uEnv.txt to use Pogo V4/Mobile settings

dtb_file=/boot/dts/kirkwood-pogoplug_v4.dtb
arcNumber=3960
machid=F78

The rest of the envs can be adjusted later.

- Sync the drive and unmount

sync
umount /media/sdb1

Take it to the Pogo Mobile and boot. After booted back to Debian, you can try to flash the default envs image again. Post the output if there is any error, and don't reboot, just leave it running.

Hey Bodhi,

Today I went right to making a live Ubuntu stick, and booting my laptop into linux. I put the SD card in, and on the first command,
mount /dev/sdb1 /media/sdb1
I get the error
mount: mount point /media/sbd1 does not exist

I am attaching a screenshot of the files on the SD card just incase it might help. http://i.imgur.com/qt5lRIK.png

Bodhi,

The command
mkdir -p /media/sdb1
worked for me, but when I tried the command
mount /dev/sdb1 /media/sdb1
it returned
mount: special device /dev/sbd1 does not exist

I had thought maybe I had to create a partition for /dev/sdb1 as well, so I entered
mkdir -p /dev/sdb1
which worked, but when I tried to mount
mount /dev/sdb1 /media/sdb1
it gave me a line
mount:    /dev/sdb1 is not a block device
Re: PogoPlug Mobile SSH?
November 27, 2016 01:59PM
Wes,

The USB drive letter is assigned by the system. So when I wrote "/dev/sdb1" or "/media/sdb1" I meant: I assume that is what Ubuntu has assigned it. The drive letter will be different, depending on how many drives/partitions you already have in this box.

So do this:

Take out the stick, plug it back in, and then find out which drive letter was assigned:

dmesg | tail -20


And replace sdxx with that in the 2 commands to mount.

mkdir -p /media/sdxx
mount /dev/sdb1 /media/sdxx

Bodhi,

I think I got the drive letter, if I am reading correct, it is p1?

I am still running into problems at
cd /media/sdb1/boot
Here is a pastebin of me running all of the commands: http://pastebin.com/ng57mgar


Quote

Copy the env text file in the new u-boot tarball that you have downloaded before.

I am confused as to where I have downloaded the tarball, and if I need to copy it from my live linux system to the sd card, I do not know how to do that either.

Thanks,
Wes

Wes,

The drive letter is mmcblk0p1. So adjust it for the 2 commands:

mkdir -p /media/mmcblk0p1
mount /dev/mmcblk0p1 /media/mmcblk0p1

Bodhi,

I think I have downloaded them onto the SD card / when I was using the pogo box, but is there any way to check? Or was I supposed to download it on my live linux boot?

Just incase I do not have it downloaded, would I just
wget --no-check-certificate https://www.dropbox.com/s/sn5w1a7dc71385p/uboot.2016.05-tld-1.pogo_v4.bodhi.tar#
On the correct machine to get it? Or is there a command to put it in a specific directory?

Thanks,
Wes

I'm honestly perfectly fine if you want me to just start over, now that I have gone through the install process (mainly) this time I can install it faster and also install the correct, updated files. I'm only good at following guides and crashing brush with your help is really hard for me, haha.

Re: PogoPlug Mobile SSH?
November 27, 2016 10:36PM
Wes,

On Ubuntu, go ahead and change directory to the SD card /boot folder
cd /media/mmcblk0p1/boot

Get the tarball
wget --no-check-certificate https://bitly.com/1sMwD7b -O uboot.2016.05-tld-1.environment.bodhi.tar

Extract the tarball
tar -xf uboot.2016.05-tld-1.environment.bodhi.tar

See if the files are all there:

ls -l | grep uboot.2016.05-tld-1
expected output:
-rw-r--r--  1 root root   2773 Jun 11 22:17 uboot.2016.05-tld-1.environment
-rw-r-----  1 root root 131072 Jun 11 22:22 uboot.2016.05-tld-1.environment.img
-rw-r-----  1 root root  65536 Jun 11 23:44 uboot.2016.05-tld-1.environment.64K.img
-rw-r--r--  1 root root 524288 Jun 12 13:44 uboot.2016.05-tld-1.pogo_v4.mtd0.kwb

Copy:
cd /media/mmcblk0p1/boot
cp -a uboot.2016.05-tld-1.environment uEnv.txt

Now, continue with editing the uEnv.txt file to adjust the 3 envs, like I posted above:

Bodhi,

I'm pretty sure all of the commands worked in the live linux machine (I wish there was a better way to get feedback from entering each command), here is the full pastebin log of that: http://pastebin.com/spvjf5hv

When I just booted the pogo with the SD card, I am getting the same error as before
ERROR: can't get kernel image!
Here is the pastebin of that if it matters: http://pastebin.com/cdVX9dV1

You need to be root user while doing this. That's the permission error when you can't extract or copy files.

Of course, you can't boot because the uEnv.txt was not created successfully in number 1 above.

Try number 1 again after gaining root. However, if this is too difficult to get it done in a Live CD, let's go to plan B . I'll upload an envs script for you to run at u-boot prompt after interrupt it, and the commands to executed it.

Wes,

The trouble you have is that you don't have a real Linux box, and the Live CD Ubuntu made learning how to do this quite cumbersome.

Let's go to plan B! plug in the SD card, power up, interrupt serial console and get the listing of the u-boot internal default envs:

printenv
And post the output here inside the post (don't post picture). Just copy/paste the text from your serial console terminal and paste here.

We are going to set a few envs on top of the internal default envs to get it to boot into Debian.

The pogo booted correctly into Debian, and now as the forum thread is so long, I'm not sure where I should continue, haha.

Re: PogoPlug Mobile SSH?
November 29, 2016 01:12AM
Cool :) OK now that you have a running system, start a new Debian thread when you have question while doing kernel upgrade. And start new U-boot thread when you have question while flashing the new default envs.

-----

Or you could just use the current system as is, to do what you want to do: set up a NAS. These installation can be postponed till later. However, you need to save the envs permanently, since you did a whole bunch of setenvs during boot, and those will disappear when you reboot the system. So reboot a few times to verify it works consistently. Then while in Debian, do it for real (basically the same commands, but using fw_setenv at Linux command line):

fw_setenv set_bootargs_mmc 'setenv bootargs console=$console root=LABEL=rootfs  rootdelay=10 $mtdparts $custom_params'
fw_setenv mmc_load_uimage 'load mmc 0:1 0x800000 /boot/uImage
fw_setenv mmc_load_uinitrd 'load mmc 0:1 0x1100000 /boot/uInitrd
fw_setenv mmc_load_dtb 'load mmc 0:1 0x1c00000 /boot/dts/kirkwood-pogoplug_v4.dtb'
fw_setenv mmc_boot 'mw 0x800000 0 1; run mmc_load_uimage; run mmc_load_dtb; if run mmc_load_uinitrd; then bootm 0x800000 0x1100000 0x1c00000; else bootm 0x800000 - 0x1c00000; fi'
fw_setenv bootcmd 'mmc rescan; run set_bootargs_mmc; run mmc_boot; reset'

Re: PogoPlug Mobile SSH?
November 29, 2016 01:51AM
Bodhi,

I'll probably start a new thread in the future if I want to go for updating the box, but unfortunately, I got another error when trying to set the envs in Debian permanently:
root@debian:~# fw_setenv set_bootargs_mmc 'setenv bootargs console=$console root    =LABEL=rootfs  rootdelay=10 $mtdparts $custom_params'
Warning: Bad CRC, using default environment

I continued on entering the other commands in the list, which none came of error. When I rebooted, the boot process worked up until
Uncompressing Linux... done, booting the kernel.
At which the system froze and I had to pull the power.

I tried re-entering the setenv commands in serial mode, but it still would not boot, stuck at the same place.

Agh I wish this thing would just work already! haha

-Wes
Re: PogoPlug Mobile SSH?
November 29, 2016 02:51AM
Wes,

Ah! I forgot :) my bad. You can't use fw_setenv until after you flashed the default envs image. For now, do the same step but add a saveenv:


Plug in the SD card, power up, and interrupt serial console, and then execute these commands (copy/paste each one to the u-boot prompt).

setenv set_bootargs_mmc 'setenv bootargs console=$console root=LABEL=rootfs  rootdelay=10 $mtdparts $custom_params'
setenv mmc_load_uimage 'load mmc 0:1 0x800000 /boot/uImage
setenv mmc_load_uinitrd 'load mmc 0:1 0x1100000 /boot/uInitrd
setenv mmc_load_dtb 'load mmc 0:1 0x1c00000 /boot/dts/kirkwood-pogoplug_v4.dtb'
setenv mmc_boot 'mw 0x800000 0 1; run mmc_load_uimage; run mmc_load_dtb; if run mmc_load_uinitrd; then bootm 0x800000 0x1100000 0x1c00000; else bootm 0x800000 - 0x1c00000; fi'
setenv bootcmd 'mmc rescan; run set_bootargs_mmc; run mmc_boot; reset'
saveenv
boot

This makes it permanent.

After booted into Debian, reboot and dont interrupt it, let it go and watch the serial console for any problem

Wes,

- Take this SD card back to your Linux Live and run file system check.

e2fsck /dev/mmcblk0p1
and see if the label is rootfs
e2label /dev/mmcblk0p1


Note: if mmcblk0p1 does not exist then find it with

dmesg | tail -20

- After verify that it has no error. Bring it to the Pogo.

Power up. Interrupt serial console and
printenv
boot

Bodhi,

I went to enter the first command, but it gave me a warning
ubuntu@ubuntu:~$ e2fsck /dev/mmcblk0p1
e2fsck 1.42.13 (17-May-2015)
/dev/mmcblk0p1 is mounted.



WARNING!!!  The filesystem is mounted.   If you continue you ***WILL***
cause ***SEVERE*** filesystem damage.


Do you really want to continue<n>?

Should I continue or is there something else I have to do first?

Need to unmount it before you can do check disk.
