Hi,

I have been using squashfs successfully for months now to read my local
newspaper (html) every day on the 770 while on the train. For me this is
my killer app!
I think you should use losetup to use the loop device. My guess is the
mount program on the 770 doesn't support looping.
I use:

1. Insert squashfs kernel module: insmod squashfs.ko
2. /sbin/losetup /dev/loop1 file.sq
3. mount -t squashfs /dev/loop1 /mnt/directory


You need to compile util-linux for the losetup program. For the 2006
software version i have put it on my website:
http://www.xs4all.nl/~kuijste2/losetup
I have also put the kernel module on this website (2006 kernel, 2.6.16):
