Aiptek MPVR, Zoran-based Camcorder (firmware update)I've recently happened upon a firmware update for a Zoran based cam that's very similar to our Saturn, the Aiptek MPVR (aka the 6800 or DV6800). The striking similarity of the firmware to our cam's firmware is why I've posted this in the Saturn area.
The firmware update can be found
at driver guide. (FWIW, driverguide uses the same username and password for each user that signs up, u:driver and p:all)
Interestingly, it has what I believe is a firmware update program near the beginning (complete with ELF header), followed by a flash disk image which includes the real firmware.
If anybody wants to replicate what I've done or explore further, here are the hex offsets for the good stuff...
firmware.o start=0x80640 end=0x27903f
filesystem.img start=0x279040 end=0x9b003f
...or if you want to automate things and have a Unix prompt handy...
# extracts firmware from firmware update.
dd if=V38main1707_Upgrade.elf of=firmware.o bs=64 skip=8217 count=32296
# extracts filesystem.img. Should be usable by
# Winimage and loopback mount.
dd if=V38main1707_Upgrade.elf of=filesystem.img bs=64 skip=40513
# patches together a standard disk image with partition
# table, firmware and partitions. Winimage can read this.
dd if=V38main1707_Upgrade.elf of=disk.img bs=64 skip=8209 count=8
dd if=/dev/zero count=2 >> disk.img #No /dev/zero? get a real Unix.
dd if=V38main1707_Upgrade.elf bs=64 skip=8217 >> disk.img
Here's the disk image information... (You can compare this to the 3.40 disk information by referring to forumer.com/viewtopic.php?p=12531>my previous post on the topic.)

ResourcesA is quite interesting. It has jpegs, a zbm, some wave files, different font.bin files, ... I'll leave exploration and reporting of that and the firmware to anyone else that is interested. (I'm on to other non-MPVR stuff at the moment.)
