I'm new to CHDK. Some weeks ago I bought a Canon SD880 IS. The firmware version is 1.02B and by using ver.req I get the following data:

[...]

I can provide a firmware dump of the 1.02B version if that's of any help (and someone can tell me how to do it?)

Interesting. Please do provide the dump; see http://chdk.wikia.com/wiki/Porting_the_CHDK for the possible methods. I haven't done this myself so I can't tell you which method to use. Feel free to extend the wiki page with the dump and extra information (e.g. ver.req/vers.req info, firmware dumping method). Otherwise just let me know and will do it. Thanks in advance.

B.t.w., I would also not downgrade firmware. That is, unless Canon tells me it is safe. ;)

Mostly works for me. One thing that doesn't seem to work is zoom during video recording. Not complaining, just letting everybody know.

No problem at all. In fact, thank you very much. I just added a comment to my original post (the one with the zip) that these comments are very welcome. I already had a section of Known Issues on the wiki page. I will (confirm and) add this problem.

If you are running MS Windows, just follow this guidance to get the dump...

has anyone tried to convert a raw file?

dng4ps-2 doesn't work (i think there is no 12bit profile/option) and the badpixel.bin in chdk script ends with "Try this script again..."

i also tried it with the windows .bat file badpixel.bat and show_bad_b.exe but got the message "file is unknown"

can somebody help?

Had to register just to express my thanks to everyone working on this; the beta is working great on my camera!

This CHDK is very helpful. Just checked it out. So thanks for your effort!

I have however two litte issues:

Parts of the histograms "RGB all", "R G B" and "Y all" are outside of the display.

After enabling the option "Enable Custom Auto ISO" in the CHDK menu and selecting "ISO AUTO" from the usual ISO-menu one can crash the system by pressing the shutter button halfway down. After pressing the shutter button, the display shows the current view of the lens and no key-input is possible. After a few seconds, the camera switches off and the lens stays outside.

The dump of firmware version 1.02B can now be downloaded from the wiki.

I partially fixed this. The only problem is that when you also enable digital zoom (don't ask me why ;)), as soon as you use digital zoom, you can no longer use zoom out optically (within the same recording). I have found this problem in more threads, but haven't seen a solution that work. The one in core/gui.c (search for DIGITAL) doesn't seem to work for us.

dng4ps-2 doesn't work (i think there is no 12bit profile/option) and the badpixel.bin in chdk script ends with "Try this script again..."

I don't think our camera is supported by dng4ps-2 (it certainly is not listed as such). I made a quick attempt to load it in Gimp and with a width of 1860 I get something that looks like a photo. Someone probably has to figure out the precise details of the data to be able to convert it.

Edit: the badpixel script doesn't work for me either. I'll add this to the wiki.

Parts of the histograms "RGB all", "R G B" and "Y all" are outside of the display.

This appears to be normal (see [http://chdk.setepontos.com/index.php/topic,1272.msg11624.html#msg11624 this thread]) and caused outside of the port specific part. You can change the layout of the screen to solve this.

I haven't been able to reproduce this. Perhaps there are other settings that play a role?

Thanks for the hint!

I tried a bit and found that problem is triggered on my camera in the the following programs (the other programs don't trigger it):
- P (Program)
- Sunset
- Foliage
- Fireworks
- Aquarium
- Digital Macro
- Color Accent
- Color Swap
- Stitch Assist (both directions)

These are basically the programs, that use the Auto-ISO functionality actually.

Did not notice this at first, since I mostly shoot in P.
