Why is that no one deal with this camera any more?

[Sjoerd]

I think there is a way to disasseble the firmware using a Intel 51 (8051) disassembler.

[muzsielod]

How?

[Sjoerd]

With IDA pro or other dissasemble software.

It decodes the firmware for about 80% then it just adds the rest as data.
Does anyone know what architecture the Digic III processor uses?

The general purpose CPU on digic II-IV is arm946E-S, configured little endian, no MMU.

This is bad or this is good?

[Sjoerd]

good i guess arm is quite common.

ARMu does something with the firmware...

Hi guys,

I've been using CHDK for my Canon P&S camera's for a while now.  I've been able to capture some amazing images using CHDK.  It has opened up a world of possibilities for me and now I have acquired a Canon EOS Rebel XS the model number is as follows:  Canon Rebel XS DS126191

I've found it hard to find the exact model of my camera but based on what I"m seeing on the forums it looks like it is a 1000D, is this correct?

If so, then I am running firmware version 1.0.3, should I go ahead and upgrade to 1.0.5 or hold off? 

There are tons of threads open in regards to to this camera so I guess my first question is, "Where do we stand in regards to a CHDK release for this camera?" 

I know the 300D was "hacked" but was using a DIGIC I and an x86 architecture OS.  I guess this one is using a DIGIC III and runs DryOS?  I'm still learning about camera firmware and development.  I've worked in the IT field as a Network/Systems Administrator for a number of years now and I hope to get up to speed on what's going on here and offer any help that I can.

If there is anything I can do to help or speed up the development of CHDK for this model please let me know. 

Otherwise, any answers to the questions I have above would be much appreciated....

Thanks guys and I look forward to speaking with you all in the forums.

Regards,
