unable to extract/compress vt2x42 firmware #50

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.use the firmware attached (or any other that can be found on the net)
2. try to extract using either extraction script.
3. I have also tried compiling squashfs-tools (v.4.0 and 4.2) with lzma support 
with no avail

What is the expected output? What do you see instead?
 ./extract_firmware.sh vt2442-11.4.1-r070201-1.3.2-r1-xp1.img out-dir

The bottom line is that me, Craig, or someone will need to dig a bit into this 
still. However, the more progress you make on your own, the better ;). If you 
are able to fix the issue, we'll happily commit the patch.
