I recently tried CHDK for my SD400, and was impressed. I'd like to get it on my SD970 IS, but nobody's provided a firmware dump yet for porting. So, here I am. I was able to get the firmware version from the camera, and updated the wiki page accordingly. (In the interim, it looks like Fe50 fixed a mistake I made when editing - sorry!)
Using CardTricks 1.44, along with the NewDryOS option and either a 16M or 1G card, I don't seem to be getting anything.I put the card in the camera with the write protect enabled, and the camera just seems to sit there doing nothing. I wait the requisite 30 seconds, then pop the battery, and finally the card. Back into the card reader it goes, and empty.dum is still empty - no strings to be found.
Any ideas on where to go from here? I've been lurking the forum, and found everything from references to some sort of "New NewDryOS" udumper, to check LED systems, and it's a tad confusing.
