I just got my 7260 and am trying to figure out how to use the Debian
distro without actually booting from the SD card.

Seems like giving RedBoot an exec command with the correct root=
option should do the trick, but I can't seem to get it to work.  Using
fconfig, I have tried the following boot scripts, but all except the
last (the default) result in kernel panic when it cannot find the root
file system:

# test - causes kernel panic:
fis load vmlinux -b 0x00218000
exec -c "console=ttyAM0,115200 ip=dhcp root=/dev/sdcard0/disc0/part3"

# test - kernel panic:
fis load vmlinux -b 0x00218000
exec -c "console=ttyAM0,115200 ip=dhcp root=/dev/hda"

# test - kernel panicc:
fis load vmlinux -b 0x00218000
exec -c "console=ttyAM0,115200 ip=dhcp root=/dev/hda1"

# this is the original, and works every time
fis load vmlinux -b 0x00218000                                 
exec -c "console=ttyAM0,115200 ip=dhcp root=/dev/mtdblock1"

I can mount the SD card with 'mount' and also via /etc/fstab and can
see the Debian distribution, so I know the card is fine.  The device
is /dev/sdcard0/disc0/part3, as described in the documentation


The "Getting Started.." Guide seems to indicate this is the correct
approach (or at least a valid one).   


If I just want to develop applications on the 7260 with the supplied
Debian distro, what is the easiest way to, for instance, run their
bash without having to deal with the dynamic libraries via ld.so.conf
and/or LD_LIBRARY_PATH and such?


I am sure there is an easy way to do this, but it escapes me right now.


Thanks for any help,

jw
