Scanning the PCB and figuring out the firmware update file format are two very important steps...

The docs for the DM320 chip are not publicly available, but we know that they have leaked out and they are now possible to find on the internet...

One thing that puzzles me. On its big brother's PCB (Zen Vision) there's a Toshiba gate array doing (most likely) an ATA interface, because the DM320's lacks proper DMA support on its Compact Flash interface.

On the screenshots of the Zen Vision:M PCB i've seen so far this IC is not present. Does this mean that the Zen Vision:M accesses its hard drive via PIO mode ?

The Datasheet links are all available on the ArchOpen Wiki:

Bah.
I've made the offer in pm to a couple of users, now I throw it open to the floor - anyone care to supply an nk.bin I can examine ?
Cheers

I helpful user noticed this thread and IMed me this link to his nk.bin file:

Edit: And yes, it appears to be unencrypted. Theres large segments that are not ARM, but I'm guessing thats the DSP code and I just don't know how to dissassemble it.
