nope... the formatting allowed me to make a 500 mb partition visible in file manager (yes, i know i'm not EXACTLY following all the instructions, but i will need ~1.4Gb for the OS)


# insmod /mnt/initfs/lib/modules/2.6.21-omap1/mbcache.ko
# insmod /mnt/initfs/lib/modules/2.6.21-omap1/ext2.ko
have been ran;
and yes, i figured that it was due to a failed mount.

#/dev/ ls showed
[...]
mmcblk0
mmcblk0p1
mmcbllk0p2

until now, the 1st partition is correctly formated into FAT16.
the second one, however, is kinda tricky:
the process did run, and the output was correct, but: after this (as read elsewhere) I simply typed:
# shutdown -r now
for a simple reboot after each step.
It did nothing, nor didn't the
# reboot

I closed my eyes on this (maybe the formatting wasn't successful?) and proceded with the
# ./nupgrade.sh 1
I quote:

Target device: Internal Flash Card, second partition (/dev/mmcblk0p2)
Using filesystem: ext2fs
Continue? (YES/no) :
i type: "y"
Installing ext2.ko module and mounting Internal Flash card, second partition...
mount: mounting /dev/mmcblk0p2 on /opt failed
Done
/home/user/bin #

the result is identical after
# cd ..
# cd ..
# cd ..
# rm -rf /opt
# mkdir /opt/

what now?

P.S. thanks a lot for your time and help
