    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.
    Don't forget what the H stands for.

    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?
