Hi, welcome to the forum !

About the 'firmware update' method not working: go back 1 page in this thread, reply #466 ...
Read the Wiki here about battery consumption

Thanks whim,

Cameraversion tool shows the firmware as '1.00B'. So I should have sx120is-100b-0.9.9-912-full.zip installed right?

I will try the suggestion " SD card format in fat32 no bootable and unlock . firmware update-> Ok-> and quick push button power on/off and wait  end of loading process " and will update the results.

:)

Hi to all.  :)
CHDK-DE for the sx120 is in beta
todo list says: save raw in folder with JPEG.

The camera uses CAM_DATE_FOLDER_NAMING  (same as sx30)
there were no NHSTUB entry for GetImageFolder, which seems to be 0xFFCEC100

void get_target_dir_name(char *out) copied from shooting.c for sx30
added NHSTUB(GetImageFolder,   0xFFCEC100) in stubs_entry_2.s and built.

results:
/DCIM/143_1401/IMG_0007.JPG
/DCIM/143_1401/ETC_0007.TMP/CRW_0007.DNG

so there is definitely a way to make beta go further  ;)

On the SX30 & G12, the third parameter passed to the 'GetImageFolder' function controls what the function returns. On these cameras 0x400 tells it to return just the folder name, other values cause it to return a file name as well appended to the folder name.

In your case it looks like the function is returning the folder name plus a temporary file name.

Maybe this parameter value is different on the SX120 - look at places where 'GetImageFolder' is being called in the firmware and see what value are being passed is as the third parameter.

Regards,
Phil.

So, I installed CHDK on my SX120. I had an 8GB SD class 10 card which I formatted into partitions (FAT16 vs FAT 32). Installed CHDK on the small partition, using the rest of the card for photos.

Here's the problem. The camera is now incredibly slow. I was using CHDK to take some pics of my friend snowboarding, and it was impossible. I missed him hitting some really good jumps because the camera was just so darn slow. I wasn't sure what the problem was, so I flipped the lock switch on the SD card (so I was no longer using CHDK) and things worked perfectly.

Sooo .. is the problem that CHDK is slow while in beta, or is the problem the fact that I'm using an 8GB SD card with partitions? Is class 10 overkill and making the problem worse? Or something else entirely?

Thanks.

You need to explain clearly what part of the process is slow. Saving, lag between pressing the shutter and when the shot is taken, ... ???

You also need to tell us specifically what build you are using. "the beta" could be anything posted in this thread.

In general, CHDK should not make the camera noticeably slower, but it's an unfinished port so bugs are certainly possible. If you have raw enabled, that will certainly make saving images slower. Size of the SD card and partitioning does not matter.
Don't forget what the H stands for.

Thank you for the response.

Using version 1.1.0-de.
 
The lag seemed to be both of those. I was trying to shoot in "continuous" mode and was getting a shot about every 5 seconds, rather than the 1 per second I was hoping for.

OK, that information about the SD card is helpful.

...and, after looking, I believe RAW was turned on. Wow, I feel stupid. Thank you for helping me. :)

Since I have your ear for a sec here, can I ask - what's the best way to manage the settings easily? For instance, when I want to shoot bracketing, can I made it so it's automatically set to do bracketing when it's in "Manual" mode, for instance? (Or, asked another way, can each mode have it's own CHDK settings?)

No. Good idea though.

For RAW you can set various exceptions, but there isn't a similar feature for bracketing. I'm not sure if the disable overrides shortcut affects bracketing or not.

You can set up (enable) CHDK bracketing in general when you don't use the continuous mode often.
Even if the CHDK bracketing feature is enabled in the CHDK menu, it only gets active when the camera is in one of the continuous modes...

Hello all. It seems that several people have gotten this working on the SX120 using their own CHDK builds. Is it possible to submit them to get a functional beta going?

I'm in the Navy and currently deployed. So going to different sites hunting for files is very slow and sometimes just not possible. Loading a page can take minutes and sometimes not load. IE6 anyone? Also getting files off the computers requires us to burn a CD. So best to get it right the first time. :)

I have the US version of the camera purchased in 2009. I tried before I left to get CHDK working and managed to get a black screen when I did the firmware update option.

I doubt I have the files with me to start over. I really want to get this working. I'm also pressed for time; in the since that I want a camera that can use CHDK before cruise is over. There are some amazing sites out at sea. Anyone seen the Milky Way? Yea, duh. It's most stars in the sky, but I mean no sh*t there it is.... WOW. During times when there is no moon and you have a clear sky, you can look up and see the purple band stretching across the sky. Truly awesome. SO, the motivation is there for me to get this working.

Any help would be welcome. I'm even willing to buy a nicer camera that CHDK is already working on. Any recommendations on that? Just from looking on the list on the CHDK Wiki the SX20 and SX200IS look pretty awesome. The SX20 is powerful and the SX200IS is very compact.

Any thoughts or suggestions? Thank you for your time reading all this and I hope you can help me out. -Sean
