Cant install archlinux (UNSUPPORTED MODEL error)

[chris5h]

So I installed archlinux on my first pogo and it went fine. I went to install it on mysecond pogo and it failed. The are the exact same model. This is the only difference:
On my second one, I tried to back up the flash memory first, following instructions I say here:

http://mehl.co/articles/installing_debi ... index.html
$this->bbcode_second_pass_code('', '
cd /tmp
mkdir usb
mount /dev/sda1 /tmp/usb
wget http://mehl.co/files/nanddump
chmod +x nanddump
./nanddump -nf usb/mtd0.oob /dev/mtd0
./nanddump -nf usb/mtd1.oob /dev/mtd1
./nanddump -nf usb/mtd2.oob /dev/mtd2
./nanddump -nof usb/mtd0 /dev/mtd0
./nanddump -nof usb/mtd1 /dev/mtd1
./nanddump -nof usb/mtd2 /dev/mtd2
umount /dev/sda1
')

Now when following the instructions like I did before here:
http://archlinuxarm.org/platforms/armv6 ... provideov3
It goes great until I get to step 10 where I need to run the install .sh file. I get this message:
$this->bbcode_second_pass_code('', '

-bash-3.2#')

I think the backup thing I did messed something up. The command prompt is -bash-3.2# instead of just # (which I dont remember it being that way the first time I did this).

Can anyone please help?

Thanks in advance

Sure thing. It's not an oxnas, it's a kirkwood.

[chris5h]

I feel dumb for asking, but does it mean I actually have a different Pogo than my first?

Does this mean I am wrong about the backup I did messing this up? Do I need to follow a different set of instruction?

Sorry for coming off as a newb, I thought I had more knowledge about this than I actually do.

[WarheadsSE]

Yup, PPV2 signifies that despite it saying that it is a B01 or even a P21, it's actually got kirkwood (aka V2 'pinky') internals. Follow those instructions.

[chris5h]

OMG Thank you so much Warhead. That is awesome. I assumed because I bought them at the same and they looked the same that they were the same.

[gaogao]

Damn, got one myself.
Two identical pogos purchased at the same time turned to be different for me as well.

Same issue here. Box indicates Pogo-P21. Botton of *gray* device indicates Pogo-E02. Serial number matches.

Might want to update the instructions on both devices to make sure that people are checking the bottom of the device and ignoring whatever the box says.

I'm starting again with the "Pinky" instructions, but hoping I didn't mess something up completely.

[WarheadsSE]

My installer will stop you if it's not a supported platform, so unless you edited the script and bypasses it, you should be safe.

[sharondio]

Your installer stopped me, as expected. Flagged the board as PPV2.

But now I'm trying to follow the instructions for PogoPlug V2, and getting stuck on the fdisk. Probably shouldn't have redone those steps, but I'm still in "paint by numbers" mode with all of this stuff.

Command (m for help): w
The partition table has been altered!

Calling ioctl() to re-read partition table
fdisk: WARNING: rereading partition table failed, kernel still uses old table: Device or resource busy

Not even sure what to do, but scared to reboot.

you can pull the drive out and put it back in to force it to rescan.
