IXUS 105/ SD 1300 1.00D firmware dump

Hello guys,

I'm a newbie here. I bought a new Canon Ixus 105 camera a month ago.While playing with it I come to conclusion, that I definitely need ability to save RAW images there.So I started to messing with CHDK.

I dumped firmware from it using Canon Basic script - here is a link to firmware:
http://drop.io/IXUS105_100D

and some info:

Firmware Version: 1.00D
Adj. Ver: 006.010
P-ID: 31F4 PAL D
SN: 073064005809

I set up a building environment and find out that new DISKBOOT.BIN has to use dancing bits 4th encoding.

Also messing up with main.c under loader directory have discovered some led adresses:

green led : 0xc0220108
AF led: 0xc02200ac
orange led : 0xc0220010

I hope you can help me procede with it. Also it would be maybe good to confirm it and put it on wiki(I'm not sure if I should/can) for somebody else to play with.

Thank you,

Onco

Looks like you've made a good start. In the future, feel free to update the wiki, that's what it's there for :)

If you want to take on porting this camera, I suggest starting a thread in the development forum. You can probably find some useful stuff in the sx210 and ixus300 threads.

Thank you guys for such a quick response...

I'll start the development thread as soon as I get something more than led blinking from my camera :P.
I have started adapting the boot proces - looking through disassembled code to find some addresses and so on(but got stuff for school, so it'll take some time) - I'm mostly comparing firmwares and editing code for SD1200(maybe not the best reference port :/).

But if anyone else has this camera and feels like having some info to share with others, than please start the thread :)

Definitely not. I strongly suggest referring to some more mature ports. The SD1200 port has serious problems and a lot of copy/pasted code and comments which do not actually apply to that camera, themselves copied from an not entirely completed port. Trying to work on this port made me :( >:( :(

Did you start developping something on your side for SD1300?
