Sorry for the attachment mistake, done now.

I've gone through all of the Canon parameters, changing them to my custom settings, and the intervalometer scripts still running for >20 shots after every couple of changes. A couple of times the camera crashed (without warning powering down with the lens still out, but that was always immediately after a user input and isn't a significant issue).

Are you able to shoot in continuous mode (shutter held down) when CHDK is loaded?
With CHDK loaded and drive mode set to continuous, I can shoot continuously (>30 frames) with the shutter held down (not in Alt mode though).

You can try to dump the camera's firmware and upload it somewhere, so we could check whether it seems corrupted or not.

From the Wiki I can't understand how to dump the camera's firmware - I can't find an extend.m file to append on my memory card.

What is that "user input"? You usually have to try very hard to make a camera crash. I can only think of something related to CHDK "subject distance" override, as your romlog appears to indicate.

Wrong choice of words. You need to put the script in a plain text file and name it "extend.m" .

That's strange.  His script does not explicitly attempt to set_focus (other than via the shoot() command).

@AndyC :  are you trying to force the focus (to infinity maybe?) using the CHDK SD override menu items ?

I think it's shutdown a coupe of times when I've interrupted a script already running - I'd (perhaps foolishly) assumed that it was a case of too much going on. It's not a big issue because it's immediately obvious, unlike a camera crash 20 seconds into a flight (as happened during a test flight 10 minutes ago...)

I haven't (yet) attempted to set_focus in any of my scripts. I tried to use 'Override Subject Distance: Inf [Inf.]', but it doesn't override the autofocus initiated by the shoot command (I think this is a known issue with this particular model that Waterwingz and others have been looking at, without a solution yet). My camera does instantly crash (no warning, power off, lens out) if I set the focus to MF, switch to Alt mode, and attempt to run any script.

I'll try this now.

Regarding the firmware dump; when I run the 'extend.m' file as a script, my camera displays:
***Started***
uBASIC:1 Unk Stmt
***Terminated***
I think this is an error message reporting an unknown statement in uBASIC, and it didn't create the desired 'CBDUMPER.LOG' or 'PRIMARY.BIN' files on my card. Could you possibly explain how I need to actually use the 'extend.m' file?

The process of dumping camera firmware uses the built-in Canon BASIC interpreter (cBASIC).  It really has nothing at all to do with CHDK (uBASIC) and CHDK does not even need to be loaded.

Thanks for clarifying (makes sense it runs before CHDK if the dump is required to create the port...).

I don't understand how to fulfill the request "1. The string "SCRIPT" must be at offset 0x1F0 of the first sector (Boot sector)." on http://chdk.wikia.com/wiki/Canon_Basic/Card_Setup; the rest looks straightforward.

It's explained a little farther down on that page :  http://chdk.wikia.com/wiki/Canon_Basic/Card_Setup#EOScard

Thanks, I really appreciate the help - just wish I could buy you a beer!

I downloaded and tried to run EOScard (v1.40); it recognizes the correct drive/format/size from the onset, but starts with an error message ('FAT32 VBR load failed'; see attached).
