Hi there guys,
I've just discovered the CHDK this week and I'm really amazed at what you guys have been able to squeeze out of these little point and shoots. I looked around for something like this when I first got my Ixus in 2005 and didn't get very far so I'm really glad that this community is now available.
Anyway, it seems that I am a little stuck getting the thing to run on my camera. My Ixus55 (SD450) has the version GM1.00a
firmware, which doesn't seem to allow updating, eventhough the camera should support it.
It seems that for some cameras, creating a "PS.FI2" file on the root of the SD card somehow makes the menu item pop up but this doesn't seem to work on my model.
Does anyone know of a way to update the firmware on this camera? There must be some kind of hack out there... I can open it up, dump the firmware, port the CHDK, etc. but from what I've seen, I'm getting nowhere without that menu item...
UPDATE: aha, it seems that by making my card bootable, I can run binaries without using the update function.. let's see what to do next.
(BTW, I will document my experiences on the wiki when I get anything to work)
