well silly me!  I've been out of the chdk loop for a few yrs. :)
Thanks, will give the big card a try.


Edit update: 
- yes, large fat32 cards will boot chdk
- getting some flakiness with dng photo capture (gray/purple images) but only occasionally
- playback sometimes doesn't read all the captured files

I just tried out tommi's latest build (1.01a) and:

- Boots properly (I have my card bootable. 4GB, FAT32)

- Shutter speed override works up till 1/2000, doesn't go above that though?
- Aperture doesn't seem to work. No matter what I set, it finally ends up at either F8.0 or F2.7. It doesn't crash for me though. The setting just doesn't have any effect.
- ISO override simply freezes the camera when I half-press the shutter button (exactly how stanley described earlier - Everything freezes, wait for a few seconds, power off, lens doesn't retract)
- The force manual flash works

- Starting a video recording just causes the camera to freeze for me too

- RAW files are being saved, though I've not checked their contents yet
edit: I opened the DNG files with rawtherapee and they seem fine. The fisheye distortion is there, though.
Couldn't find anything to open the CHDK RAW files though

- HDR script takes one photo and freezes
- Interval script works!
- Motion script works, too, but is so slow it couldn't even capture my hand, let alone lightning  :D

- All the knick-knacks work - OSD layout, colours, fonts, icons, file browser, text viewer, calendar, games :P

Also, is manual focus possible on this model?
Thanks :)

I just updated movie_rec.c for 1.01a.

Please find attached 1.01a binary.

update: and of course the movie_rec.c source file  :)

Update: removed binary because no or wrong functionality, newer version available in later posts

Am I doing something wrong? Because it crashes just the same when I start video recording  :-[

EDIT: It doesn't crash the same way. Last time it froze. This time it simply switches off immediately with the lens still extended.

On my 1.00c camera I am able to start video recording. I do this via long press of video button.

For 1.01a firmware I found 5 locations with different addresses. These I changed to the ones from 1.01a firmware. I am not able to test this by myself because I have no 1.01a camera.

jstanley, wake up. we need you here. ;)

My new movie_rec.c should be reviewed. I will do it as well once again, but sometimes you don't find the error by yourself.  :)

Wondering why 1.01c users are not complaining about video recording issue, maybe not yet tested this feature?

Because in 1.01c firmware function is at another firmware location. I adapted movie_rec.c accordingly.

Please find attached binary and movie_rec.c for 1.01.c.

New 1.01a binary because I found one small difference (don't think that this will be the final solution, but we should give it a try).

No luck it's just the same :(

Edit: here's exactly what happens, if it's of any use

- Long press video button
- Screen blinks
- "Calc" appears in video bitrate calculator box
- Screen blinks again
- Bitrate calculator disappears and the ordinary Canon "Rec" in red, with a red dot, appears on the right side of the screen
- Camera switches off

Same behaviour on 1.01c.

Tested out some of the other functions and they seem to work well !!!

RAW shooting creates 18M raw files (although I've got no way to develop them).

Great progress Tommi.

Can someone confirm that RAW files have good content?

Wanted to take some DNG pictures but I was not able to create the necessary badpixels.bin file. Tried to do it several times but it always failed.

Just created an empty badpixels.bin file in CHDK folder, DNG picture shooting is now possible but no usable results.
