IXUS 100 IS (Europe) / PowerShot SD780 IS - Porting Thread

I have just noticed that all of my DNG photos have a black stripe, few-pixels wide on one side. Is it just my camera, or do you guys also get it? On jpg there is no stripe.

Yes, I have it also.

I have a 16 GB card and wanted to use 2 partitions (first - bootable 16 MB FAT16, second - main partition with the rest of the space and formatted FAT32). When I power up CHKD it doesn't detect the second partition at all (in "misc. stuff -> swap partitions" says the card has only one partition). Does this work already?

Additionally I tried "Make card bootable" and "Create card with 2 partitions" and both resulted in camera shutdown. But at least it didn't destroy any data. 😀

* Include multipartition/boot from SDHC support.

I acutally looked there but missed it. At least I can now report that it does not work. 😀

I'll include the black stripe as a bug to fix...

Just purchased 2 SD780-IS for stereo movie recording. I've successfully installed the pre-alpha. Oh boy, oh boy, oh boy. Keep up the great work HarpoMa and other contributors. I'll chime in again if I have something to contribute.

I hope there is continous development in the background, altough the forum is not updated recenlty.

Anyway, UP to this topic.

Still working - but slow due to life.

HarpoMa, thanks for all the hard work so far! I'm amazed at the skills of all you CHDK developers; wish I could program at that level. C on Unix is all I know.

Got some questions for the SD 780 pre-alpha build:

Does this work if you're loading onto an SDHC card as opposed to an SD card?

Is the procedure the same as when I put the CHDK software onto my SD 400, which was downloading the appropriate build based on certain firmware, then using "Card Tricks" to make the software auto-start when i turn on the camera.

Does this build have the video paramater "Video Mode" where you can set it to "Bitrate" mode and have the camera record video at constant "1 X", "2 X", "3 X" bitrate levels?

If the above question is yes, would this work with the SD 780, HD (H.264) video mode. That is, the ability to record HD video at constant (desired) bitrate?

Keep up the good work! Thanks!

HarpoMa

SD or SDHD it matters not.
Don't know exactly the prodecure but if you make the card bootable in cardtricks and then copy the file to DISKBOOT.BIN it will boot when locked. If you name the PS.FI2 then select firmware upgrade it will work.
No bitrate per say but there is a quality setting that affects bitrate. Yes it works nicely with regards to the H.264 720p mode. You can't force a desired bitrate only quality.

Harpoma,

I'm really excited to see how this develops. Please let the non-developer users know how we can help you in any way.
I have a 780is and am running the CHDK on a Mac. Mostly interested in using the CHDK hack for time lapse recording scripts (Ultra script) and stereoscopic filmmaking.
If we can run any testing or beta that would help your process let us know.
Thanks!

You can test and report based on last build.

Does anyone know how similar the SD780 code is to the SD940? The SD940 is a newer camera with an improved lens. The appearance and features seem similar. I'm hoping some of the porting effort going into the SD780 could carry over to the SD940.

Each camera needs it's own port. It can help to have a similar camera of the same generation to refer to, but the SD940 is probably closer to the sd980 (both use a newer version of DryOS)

I want to see if blinking works on my 1.00B SD780. Having trouble getting the packages required. HarpoMa, do you have them handy to be posted somewhere?

HarpoMa

@wasabi1023

I'll post my blinker stuff (however it really depends on a lot). If I was to blink a camera again I would use the sound card osilloscope methods talked about elsewhere. This method is a lot more controllable and you can determine the timing required between bits a lot easier. I was extemely lucky with my blink to serial port.

Harpo

You really shouldn't have to blink to get a dump of a different firmware version of one that is already known. The differences are normally very minor, hacking up udumper or an existing CHDK loader to write a full dump should be quite a bit easier than blinking.

redfox74

I'm a developer . I want to help you to port the chdk to Ixus 100 is if is possible ... i don't know exactly what i need to start to help your project ?! ... onother question ... i see that there're some tips to use chdk and rc reciver by usb to control the cam remotly is this features supported by your port now ?
Best Regards

The autorun works well with the DISKBOOT.BIN file listed as an attachment to the first post, however when I compile this file myself using the zip of the source code that is also in the first post and put it on an SD card it doesn't boot CHDK on the camera. When I turn on the camera the screen just stays black and the lens doesn't extend. What am I doing wrong?

The funny thing is, my own compiled PS.FI2 file this loads with no problem on the camera.

I am using binutils < 2.19 and I have tried setting the execute flag on the file. This is all in a gcc cygwin environment.

Thanks.
