Pogoplug mobile: Invalid CRC

[benm]

Hello,

I wonder if someone could help.

I have been trying to get netconsole to work on my Pogoplug Mobile. For some reason, most of my failed attempts have triggered a reversion to the stock Pogoplug firmware. Each time this has happened, I have logged in, and reinstalled uBoot in order to reboot into Arch Linux.

$this->bbcode_second_pass_code('', '
killall hbwd
cd /tmp
wget http://archlinuxarm.org/os/ppv4/ppv4-install.sh
chmod +x ppv4-install.sh
./ppv4-install.sh
')

Now however, the ppv4-install.sh script fails with a CRC error.

$this->bbcode_second_pass_code('', '
/tmp # ./ppv4-install.sh

Does this mean my flash is corrupt? If so is there anything I can do about it? (Probably not I suppose!)

Many thanks,

P.S. Output from dmesg:

$this->bbcode_second_pass_code('', '
<6>[ 5.900000] XCE: BLPARAMS: -- Loading properties [c4b95ecc].

Problem solved!

My initial guess when I posted this question was that the area of NAND where the environment is stored was bad. But dmesg didn't show any bad blocks (at least not there).

So I copied fw_printenv, fw_setenv and the configuration file fw_env.config into the root filesystem of the stock firmware and undid the changes I had made earlier trying to get the netconsole to work. I can now boot Arch Linux again.

Incidentally, according to this post

http://forum.doozan.com/read.php?3,14,10863#msg-10863

the Arch version of uBoot does not support netconsole anyway.
