Do you checked the empty.dum file with the Cardtricks "string" function or by viewing with a hexeditor? I am asking, because the dump will start somewhere in the middle of the empty.dum file, and not from byte 0. So it is possible to overlook the dump if you take only a quick view with the hexeditor on the first KBs.

Also remember udumper doesn't know anything about the filesystem at all. If the card wasn't freshly formatted with empty.dum as one of the first files created, the dump might not be inside the file at all. If you are on a *nix system, you can just dd the sectors that udumper would write to.

ISTR some cameras have needed more or less of the RAM zeroed for WriteSDCard to work.

SD780 - access to physical buttons and swithces

Is there a list of names for physical buttons and switches for SD780?

1. I need to create certain functionality when some buttons are pressed
(and specifically, I need to add power down when 'Power' button is pressed. For whatever reason my power down button does not work when camera operates in ALT mode)

2. I need to block the buttons I do not use, meaning pressing these buttons results in n o action.

SD780 - cleaning the display

How to clean the display entirely from over-writes.
I use cls command and it cleans everything but 'x2' at the top of the LCD for digital zoom and ALT at the bottom. Also there is focusing rectangle. I want them all OFF!

Is it any way to do it?

SD780 - digital zoom. Reply to Microfunguy

I have indication that digital zoom can be set in ... DISKBOOT.BIN file?
When I use my SDM SD card it sets digital zoom to x2. (It does it every time on start up. I guess I set it manually at some point and it became written to the card)

If I start camera without the card digital zoom is set to x1 - no magnification.

Unfortunately i do not know what to write to set digital zoom. Any suggestions?

Hey, great work! Keep going!

I managed to run "Pre-Alpha Firmware (v8 updated Dec. 3, 2009)" on mine. Functionality seems to be as described.
Things I (also) noticed:
- menu disappears in shooting-mode when AI-Focus engages
- RAW files cannot be read (~~tried with Camera RAW, irfan-view~~, just read the CHDK & RAW thread, will try this)
- when I try to enable DNG it tells me that badpixel.bin is missing
(~~badpixel.lua does not seem to work, only says "Run in record mode" ... which I did. Any ideas?!~~
fixed by uncommenting the loop that checks for record mode, see post on page 19 by Boondaburrah)
- histogram doesn't work when set to "Always" (when set to "Shoot" it works, but seems to hang after a while)
- in display-mode, the "alt icon" appears as a white rectangle (maybe identical text-colour?!)

Will be happy to do more specific testing if required.
Again, great work guys!

What do you mean ?

When I use my SDM SD card it sets digital zoom to x2. (It does it every time on start up. I guess I set it manually at some point and it became written to the card)

There is no function that sets digital zoom.

What happens if you delete or temporarily rename the CFG file ?

See the post on page 19 of this forum, by Boondaburrah, once you remove the piece he mentions in a text editor and reload to your camera, then you can run it with alt, just make sure to read the message it gives you after, I didn't and it took me a few trues before I saw that you have to press SET after. Gives some great RAW files. I am on a Mac and can read them with Gimp, and GraphicConverter. If you do as well, make sure to start GraphicConverter before Gimp, and then open the files in Gimp, and GC will filter it first and you can set white balance, etc, in a preview, before the image opens. I also get the white square in display mode, but hadn't thought too much about it, just assumed, rightly, that chdk was running then. Besides the white square, the menus seem very stable in display mode, they don't just disappear like they do in record mode.

Thanks, danstr & Boondaburrah! Hadn't yet made my way back through the thread quite far enough. Erasing the loop was the thing I was thinking about myself already, though I assumed it's vital to check for the state... but true, if you make sure it is in record yourself then you don't need to worry. Can write DNG now, not quite sure yet what to use for the workflow, though.

Hey guys i got a problem. I replaced the v8 diskboot and ps2 and can load the chdk on my ixus. But i can not use override shutter speed. I tried everything but it will not work. Where is my mistake? With v5 it worked very well

Check your settings...
"Disable Overrides" (not [on]),
"Override Shutter speed" + "Value Factor" / Shutterspeed enum type"
(e.g. with "Shutter speed enum type" set to [Ev Step], you also have to enable the override by setting a "Value factor")

You should also use a clean CHDK config file -> rename or delete [tt]\CHDK\cchdk.cfg[/tt] on the SD card, a new config file with default values will be created on the next CHDK start.

twista

i renamed the cchdk.cfg file. then i set
disable overides to off/disable
include autoiso&bracketing is on
override shutter speed is 6
value factor is 1
shutterspeed enum type is ev step
but it only shots with standard settings like iso250 f3.2 1/60 it doesn't matter what the shutter speed is :S

override shutter speed is 6
but it only shots with standard specifications like iso250 f3.2 1/60 it doenst matter what the shutter speed is :S

"Shutter speed" 6 ? - i guess you mean 6.3
Your settings seem to be correct; you should see TV:6.3 on the CHDK OSD when the override is active.

What camera mode do you use ? - try M mode, no continuous mode

BTW - don't forget: by default, the settings will be reset on power off ("Clear override values @start" menu entry)
You could also try the SDM version: http://stereo.jpn.org/eng/sdm/download.htm

twista

sry you're right it was 6.3 shutter speed
i can't see any TV:6:3 on the osd
i use the manual mode in the middle. above is automatic and under the manual mode is the movie mode
maybe i should format the sd card and copy everything new. maybe there are some old files from v5 who are crashing with the new diskboot und ps2 file?
i'll try to get the sdm version on the sd card when i got some time

thanks for the efforts so far. i hope the work is still in progress for this camera model.

i managed to save DNGs, but i can't open them with Photoshop CS4. any idea on how to do that? Picasa and Irfanview are able to open the DNGs.

Oh HarpoMa, where are you?

I come here every day hoping to see the v9 update or the first BETA... 🙁

Are you having troubles? We need you!

I really appreciate what you have done! Thank you for your hard work!

I second this. I also check back here often to see any improvement, but so far, nothing.

I'm working on zebra atm. When I get that finished I will release a 875 patch and the new firmwares.
Harpo

danstr

😁 Thank you, HarpoMa, very good to hear from you!

HarpoMa

Since it appears zebra will take a lot more work than I thought I will post this 875 patch that adds SD780 support. Don't be surprised if zebra crashes.
