seems that this model have one firmware version. hovewer, i don't know if there were any official firmware updates or not.
Theres no Firmware Update from Canon as far as i know. By now it looks like there only 1.00C!
It's just to be shure, because sometimes Canon ships there Cameras with different firmware version or maybe even hardware versions but not necessary release an official Firmware Update... (thus update is only needed if firmware has a bug and they fixed it...)

Current status

  • led addresses are correct
  • CreateTask address should be correct
  • all other addresses if found should be correct
  • Compiled against current trunk 462
  • port is based on Canon IXUS 850IS / SD800 source from current trunk (VxWorks 5.5)

also changed:
  • stubs_entry_2.S

todo:
  • capt_seq.c
  • movie_rec.c
  • a lot more...

for most addresses i also tested alternate addresses from stubs_entry.S and stubs_entry_ida.S .

Get Source v2 *BETA* here.

Get Firmware 1.00C dump here from paul.luminos.nl.

Please, acould somebody with better asm skills have a look at this? I know it's not easy if you ain't got the camera in your hands... also i'm aware of that most devs are working on DryOs stuff.

Maybe i missed something important or some addresses are wrong. I double checked everything twice, but there must be still some errors !!!  :blink:

Thank you very much for your afford and time spend on help me out !!!

Yes, i take some time to understand all this... thats what i did over the last few weeks... this are only snippets of model specific chdk  source with assembler and c... chdk source is huge... the devs must be real geeks ! much respect !!!

not sure if i have said it yet but i am also on 1.00c
OK

what is this last post? are you just looking for coding assistance?
Exactly!!! I need help by somebody with a little more expirience to have a look at it... maybe I'm able to find what wrong by myself at some time... but theres also some kind of time limit where i have to think about wasting my time instead of buying an already ported camera...

    * your firmware version: Firmware 1.0.0.0

This isn't the firmware version, you need to find it with this method ;)

Looks like we've had an error.  It seems to be working fine though.

* you own a Canon IXUS 900 Ti / Powershot SD900, so i can see how much users are interessted in this port
Yes, I have one and I'm very interested!

* if you tested this port with your camera
I haven't tested it yet.  I'm not the only person using the camera, so I need to ask the others first.

* want to contribute
Yes, I'll try to help with testing.

@dixie
Thanks for your answer!

Yes, E18 is Lens ERROR. Have your read Canon & E18 Error ? Maybe its happend sometime before, but if there no problem, be happy!

Currently i'm trying to setup qemu to emulate the 900 like written at the WIKI. Did somebody tried this already?

It looks like you're the first.  Are you aiming to step through h_usrKernelInit() to see where it stops?
