How can one extract the files from this? Tried mounting it as a cramfs or sqaushfs, no-joy. Any other ideas?

Try jffs2 then - search the forum for "mount AND jffs2"

Dear bam,

(using koen's way of saying it) lardman and adf is bullshit.
initrd.bin is similar to initrd.img used in normal linux boot.
It is a gzipped image. To mount it, first gunzip, plus
kernel have to have initrd support, then use this command

mount -t ext2 -o loop initrd /mnt

to mount it.

br,

felix.

I wouldn't, you just appear to be rude (even more so as you're not actually right).

No initrd.bin I've ever seen for a Zaurus uses ext2, they are always compressed, which means a choice of ro cramfs or rw jffs2.

Assuming it's not cramfs, best to try jffs2.

The best way to check it is to use 'file', however:

Code: [Select]
angstrom@serenity:~/website/unstable/images/20060725/c7x0$ file *
Angstrom-bootstrap-image-test-20060725-c7x0.rootfs.ext2:    Linux rev 0.0 ext2 filesystem data
Angstrom-bootstrap-image-test-20060725-c7x0.rootfs.img:     data
Angstrom-bootstrap-image-test-20060725-c7x0.rootfs.tar.bz2: bzip2 compressed data, block size = 900k
modules-2.6.16-c7x0.tgz:                                    gzip compressed data, from Unix, last modified: Tue Jul 25 14:29:58 2006
updater.sh.c7x0:                                            data
zImage-2.6.16-c7x0-20060725122119.bin:                      data
note how it differs from:

Code: [Select]
angstrom@serenity:~/website/unstable/images/20060725/a780$ file *
Angstrom-bootstrap-image-test-20060725-a780.rootfs.jffs2:  Linux jffs2 filesystem data little endian
Angstrom-bootstrap-image-test-20060725-a780.rootfs.tar.gz: gzip compressed data, from Unix, last modified: Tue Jul 25 13:51:54 2006
the zImage and roofts.img both have the sharp-sl header prepended, so file doesn't recognize them. That header could also explain why it won't mount/uncompress/etc

I have been able to mount jffs2 filesystems from pdaX certainly, and also the Sharp cramfs offerings.
