SX200is Porting

[OldGit]

As we now have a confirmed "good" dump for the SX200, and I and others are attempting the work,
this is a just a placeholder for progress / problems etc.

Referrence port SX10-101A ?

Hm, no one with an sx200 here?

If you aren't reasonably proficient in C and some flavor of assembler, there isn't really anything you can do yet.

Hi,
sorry for the adsence, my connection was dead for the last few days.
Progress....
I have the boot process 2/3 done, camera restarting but dying at the core spytask creation around the "restore configuration" / "gui initialisation" steps.
This is due to the lib.c not being finished yet.
I have found the "hook raw" stuff but am still looking for the rest of the stuff (get_vid... etc.)

Also need to confim the SD card writing, I then hope to be able to get this thing booting up to the CHDK menu.

This will still only be the first stage so I still have a way to go.
I'll heep trying but if ayone can find, or has the vid stuff etc please shoot.

As this is my first port I am a bit slow at it, but if I get to the boot up point I will post again.

attaching of your source code to forum would speedup development

If you use canon's newest firmware you can shoot in RAW without any hacks. (source http://teknogadget.com/canon-powershot-sx200-is.html)


I also want to thank OldGit for the good work so far It would be cool to see the source

WOW thats great news! But where do I get this Firmware?

[blaster]

I can't find the firmware on canon's site :\ If there is such a firmware I guess their ship their newer produced sx200is camera's with the new firmware. I get mine tomorrow. I can check and send you a pm. If the newer produces sx200s is shipped with the new firmware it should be possible to get it from canon support center.

edit:
sorry for off topic

edit 2:
got my sx200 today. old firmware

[ratz1967]

The new firmware seems to be:



Firmware Ver GM1.00D <<<<<<<<  D

Hi everybody

First, thanks to all developers around here, CHDK is really something.

Very interested in the port for the sx200.
I have a bit of knowledge in c although I doubt it can help (I'm too inexperienced I think).
Any other way I can help please tell me.

That article was from Febuary, before the camera was even released,  making it hopelessly out of date.

Got the internet back at last.
Before I lose it again here are the sources I have so far.
step1.7z - 0.03MB
As always, use at your own risk.
This set includes all files except Primary.bin, I have included the core.c and main.c as well as camera.h
Core.c has debug flashing in it.

I found that this slowed down the boot and then allowed the lens to fully extend and the screen to come up.

Buttons are all over the place, autoload not working yet, haven't set sd_protect value.

Next is to get the CHDK menus up and the buttons working correctly (I hope)

If someone could take a look and check waht I have so far I would be so gratefull, this has been driving me mad.
