Pogoplug Pro / v3 - flashing U-Boot / running Debian when internal rootfs isn't accessable

I've got a fiew Pogoplug v3 / pro devices which doesn't boot propery.
With serial attached I noticed that U-Boot env is modified.
The stock kernel is booting up but a rootfs cannot be found.

I think a fiew people have modified their boxes in that way because there wasn't any newer U-Boot available and accessing / booting from USB isn't possible in stock U-Boot.
So they used the stock kernel to bring up the USB.
Because I only have these boxes and no rootfs that fits this situation, I decided to go forward in another way.

As you can see, the stock U-boot is up and running:

Now we need network access.

As you cen see, the uImage is quite big but as you'll see, this will boot up.
For this to work, you need do adjust the bootargs:

CE>> setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootfstype=ext4  mac_adr=0x00,0x30,0xe0,0x00,0x00,0x01 rootwait mem=128M poweroutage=yes
CE>>

Don't forget to plug a prepared rootfs (Debian Jessie or Wheezy] with the same kernel which was used for creating uImage and uInitrd.

Now let's boot:

CE>> bootm 0x60500000 0x60e00000
CE>>

The kernel and rootfs should be up and running in a fiew time.
Now you can proceed flashing U-Boot and prepare all things to your needs.

As mentioned in another thread (STG-212) there could be some problems
accessing /boot and / or /boot/dts when using the given env file and ext4 rootfs.
On this boxes this doesn't occour only after kernel upgrade, this could happen on first boot (with new U-Boot and rootfs),
so be warned.

A solution is use a seperate (fat formatted) /boot partition.
For this to work, the env has to be changed in the following way:

setenv dtb_file '/dts/ox820-pogoplug-pro.dtb'
setenv load_dtb 'echo loading DTB $dtb_file ...; fatload $bootdev $device 0x62c00000 $dtb_file'
setenv load_initrd 'echo loading uInitrd ...; fatload $bootdev $device 0x60e00000 /uInitrd'
setenv load_uimage 'echo loading uImage ...; fatload $bootdev $device 0x60500000 /uImage'
setenv uenv_read 'echo loading envs from $devtype $disknum ...; if load $devtype $disknum:1 0x60500000 /uEnv.txt; then setenv uenv_loaded 1; fi'

Please note that you have to use the correct DTB for your device, otherwhise it will not boot.

hi pengu,

where can I got uImage/uInitrd if I dont have a environment to build them?
My Pogoplug Pro were install with an official openwrt version.

You can use the oxnas rootfs + kernel from here
Another way is described here.
It's possible to use the Kirkwood rootfs, build a Oxnas kernel (what I've done) and install it to that rootfs.
Atm I'm using vanilla 4.4.16 + patches from OpenWrt + modified config from the Oxnas Rootfs + Kernel thread.

The only thing you have to keep in mind is that you have to embed the DTS when (re)create uImage and uInitrd.



oxnas pogoplug rootfs Debian Jessie, Kernel 4.4.11
Kernel 4.4.16

it's appreciated!

I was struggling with the egg-chicken problems for many days and cannot found the valid Arch Arm URL int the stick list.
I already flashed the latest Uboot according bodhi's post in offical openwrt, but cannot boot any debian system to install latest kernel and rootfs.

Thanks again.

So can you run the rootfs from here yet?

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.

thanks bodhi,

yes, i thought the steps complex in the past.
I think I should boot with the kernel/initrd firstly and boot into the usb/hdd rootfs and then update the kernel.
But after your rootfs url, I extracted them into usb stick and boot with your latest uboot and it smoothly boot into the debian7.0 syste.

Thanks again!

Hello Pengu,

Your post is very clear, but I didn't find " ox820/uImage" and "ox820/uInitrd", could you direct me where to download these two files?

Your help would be appreciated!

asterix ,

Do you still have problem installing?

My B01 bricked, bought a serial to USB cable, connected, but don't know which file I should use to flash nand, frustrated!

You only need to flash u-boot to NAND. Not kernel files (uImage and uInitrd).

- Create USB rootfs:

- Plug in this USB rootfs,
- power up, interrupt serial console, and

version
printenv
boot

And post the entire serial console log. This is so I can see what's you have installed, or whether your u-boot on NAND is still good.

Thanks Bodhi,

I flashed openwrt uboot, but pogo didn't boot up, so I am looking for a way to flash by debian......

Sorry Bodhi, I am new on embedded device, don't have more idea about uboot or bootloader , this is why I am looking for step by step process to flash pogoplug b01

asterix,

These are summaried steps.

1. Create Debian rootfs on USB. You can do this using any Linux box (Ubuntu, Virtualbox,...):

http://forum.doozan.com/read.php?2,16044

2. Boot into stock OS, and then flash new u-boot from there:

http://forum.doozan.com/read.php?3,16017

3. Plug in the USB Debian rootfs, and reboot.

If you have question along the way then stop and post that question.
