<< < (3/5) > >>

Lost_prophet:
Here is my original post. (posted in a wrong forum originally (my bad  :) )

I have one dead Zen V plus 2G (died because i fell in salt water with it )) ) .

so i disassembled it and here the photos of mobo

so whats in the archive
1 st - A battery. 560 mAh p\n BA20603r79919 ))

2 - mobo - part with screen connector
3.1 - mobo lower part  there is some sort of wire on it so it is a picture with it.
3.2 the same but without wire stuff

There is a Samsung Nand - k98g08u0m x2
Philips Fm Stereo chip tea5767 http://www.ortodoxism.ro/datasheets/philips/TEA5768.pdf here is the datasheet
Phison ps3002t CF CONTROLLER
Infineon Flash HYB25L25616af

Creative ca0209-HA6 chip (some Sigmatel ? )
 and a small shiny oscillator  xD named "hkc 24.000с6"    i think you will be able to read the rest.

MarcGuay:
According to this post, and the discussion it links to: http://www.epizenter.net/comment.php?comment.news.271, the Creative branded microprocessor is a Sigmatel STMP3600, which has had linux ported to it already (http://linux.sigmatel.com/), so a lot of the low-level work would presumably already be done?

@MarcGuay: Do you think we could use the ported Linux kernel to boot up the Zen?

Does anybody have new information regarding the encrypted firmware?

I tried reversing it (actually haven't done much on it to be honest) but it feels like searching for a needle in a haystack.

I'm willing to help and learn (I'm an experienced assembly and C programmer though).

How far did you get last time?
Currently, zenutils (in SVN) should allow you to decrypt the whole package and to fiddle with it.

About the ported Linux kernel: it won't do much without some (reverse engineering) work because you don't know how to drive the LCD (controller) etc

Well, I didn't do much besides the few times you and me chatted about reversing with IDA, but I'm willing to give it another shot ;)

So, after we get the LCD (and some other things?) working we could use parts of the ported Linux kernel?
