Where do I go to find older CHDK builds (especially vrsion 1.2)

Hi, I recently updated to version 1.3, and did not backup the card, or save the original 1.2 download.

While 1.3 has some great features that I like, I have once in a while had trouble many scripts, and saving raw files. (some scripts will simply cause no raw file to be saved, or save corrupted raw files, for example, attempting to do an HDR bracket, or time lapse, will have raw files simply not be saved, or a number of 38KB raw files. (attached a sample)

anyway, at least for now, I would like to downgrade to the 1.2 builds, but cannot find the latest 1.2 build for the canon powershot SX230 HS (firmware 1.01B)

The final 1.2.0 builds are conserved here :   https://app.box.com/s/p7ih4eqbcj8r9u09iwcj 

You will need the common file in    _common_files.zip plus the sx230hs-101b-1.2.0-3770_BETA.zip file.

FWIW - I do not believe your issues are in any way related to the update from 1.2.0 to 1.3.0.    If it is, this will be a surprise to all the CHDK developers and we would like to know a lot more about what you are seeing.

As step one,  please confirm that reverting to 1.2.0 solves all your problems.

TIA

I recorded a video of the issue, but basically what happens is if multiple images are taken either with the shutter button held down, or a script set to take multiple images, only 1 or 2 raw files will be saved.

If multiple images are taken in a row in pretty much single shot mode, then the raw files save fine every time. (I do not have the option enabled that only saves a single raw file in a series)

With version 1.2, the issue goes away.

I can't think of any changes that would cause this - there don't appear to be any SX230 specific changes between the 2 versions you are using (except removal of unused GPS code).

When you updated to 1.3 did you replace all the CHDK files (including modules) or just the diskboot.bin file?
What happens if you turn off DNG and just save CHDK RAW files?
Have you tried resetting all your CHDK settings (delete the *.CFG in the CHDK directory; but keep a copy so you can restore them if needed)?

Can you post the script you are using please.

Phil.
CHDK ports:
  sx30is (1.00c, 1.00h, 1.00l, 1.00n & 1.00p)
  g12 (1.00c, 1.00e, 1.00f & 1.00g)
  sx130is (1.01d & 1.01f)
  ixus310hs (1.00a & 1.01a)
  sx40hs (1.00d, 1.00g & 1.00i)
  g1x (1.00e, 1.00f & 1.00g)

I will try the latest nightly of 1.3

my install process is always erasing the card, then extracting the zip file, then copying everything except the text files in the root folder to the SD card. The first thing I do is then disable the CHDK boot logo, make the card bootable, disable the temperature info and other random OSD elements, then create the badpixel file with the camera set to 1600ISO which creates a 40KB badpixel file. I then enable raw and set the DNG to 1.1

The script that I am using is attached in this reply (awesome script, it works quickly, and allows for many exposures to be taken with smaller step sizes so that HDR images have less noise).


Edit: I just tried the nightly build sx230hs-101b-1.3.0-3903-full.zip  same issue with the settings from the video. (the card was formatted first)

with DNG disabled, the issue still happens.

This port had unresolved issues with the file counter

Don't forget what the H stands for.

cool, will use that (I think I lost that script some time ago, and ended up grabbing one from the main wiki)

For the raw files not saving, it happens even when not using a script, and simply using the continuous shooting, this it is not a script issue.

Between version 1.2, and 1.3, version 1.3 has different raw options, as it allows you to even change the crop size of the raw file. (changing the crop size does not have an impact on the issue).

Other than that, CHDK has been the best thing to happen to canon point and shoots. (pretty much all of the images were taken with its raw function https://www.flickr.com/photos/razor512/

The link I posted explains why this happens. I posted a second test build to further diagnose the problem (in May of 2014) but never heard back, so I made no changes in the code.

Sorry for not getting back, I just enabled email notifications so that I will be able to better keep track of these threads.

For that post that you linked to, I ran the script and CHDK release and posted the results in the linked thread.
