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

.
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?
