getting back to booting pogo
January 04, 2011 01:17PM
I have been using the nand instalation for some time and now I need to get back to the original system to check how a script would work in that environment.
I boot it with
run pogo_bootcmd
from the uboot that greets me with: 
U-Boot 2010.09 (Oct 23 2010 - 11:49:22)
Marvell-Dockstar/Pogoplug by Jeff Doozan


It loads the kernel etc. and finally I get a lot of: 
[    9.340000] Error: jffs2_decompress returned -5
[    9.340000] JFFS2 compression type 0x07 not available.
[    9.350000] Error: jffs2_decompress returned -5
[    9.350000] JFFS2 compression type 0x07 not available.
[    9.360000] Error: jffs2_decompress returned -5
[    9.360000] JFFS2 compression type 0x07 not available.
[    9.370000] Error: jffs2_decompress returned -5

and after that 
[    9.600000] Kernel panic - not syncing: No init found.  Try passing init= option to kernel.
[    9.610000] Scheduling watchdog timeout to force reboot...

and it reboots


I have found another thread with this error
Jeff, You suggested to do the following: [I fixed one error - nandwrite was targeting mtd0 instead of mtd2] 

# Restore mtd2
wget http://plugapps.com/os/pogoplug/ce_mirror/ce_ramdisk_v2.0b.img.gz
unzip ce_ramdisk_v2.0b.img.gz
flash_erase /dev/mtd2
nandwrite /dev/mtd2 ce_ramdisk_v2.0b.img


After doing this I got: 

root@debian:~# flash_erase /dev/mtd2
Erase Total 1 Units
Performing Flash Erase of length 131072 at offset 0x0 done
root@debian:~# nandwrite /dev/mtd2 ce_ramdisk_v2.0b.img 
Input file is not page-aligned. Use the padding option.
Data was only partially written due to error
: Success


And now it boots like that: 
...

I guess the problem can be caused by mounting mtd2 with -t jffs2 when running debian.
