Pogo mobile nand bad block - installation failure (5 replies)

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'

<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
