Help Dumping Firmware for SD1000/IXUS 70

Hi,

I've recently purchased a SD1000, so I am currently working on getting the firmware dumped for this camera.  This is the first camera that I have attempted to dump the firmware from, and I'm finding some of the info in the Wiki a bit vague and/or confusing and would greatly appreciate it if someone with experience dumping firmware could chime in.

Here is what I have done thus far:

  • I am using the Phototransistor/Camera LED Blinking method to get the firmware.
    • Phototransistor is wired up to a 3.5mm Headphone plug connected to the mic-in of soundcard on computer
    • I can verify that I am getting a response to light by the Phototransistor
  • I have modified the G7 blinker to work with the SD1000
    • Changed LED Addresses
    • Cam ID in Make.bat).
  • I have compiled the blinker source on Windows.
    • One FIR file with Starting Address: 0xFF800000
    • One FIR file with Starting Address: 0xFFA00000
  • I am using Audacity to record the blinking
    • 96kHz
    • 16 Bit (8-bit not selectable)
    • Mono
  • The blinking finished in about 45 minutes (per FIR file)
  • Exported RAW file of recording
    • 8-Bit Unsigned PCM

Questions:
  • Once I have recorded the blinking, do I need to do anything to the files before processing them with ADC.exe?
  • Why do I do the recording twice (starting at 0xFF800000 and then again from 0xFFA00000)?  Am I supposed to merge these two files and process the merged file with ADC.exe?
  • When I run ADC.exe on the exported files (merged or individual), I get a lot of lines saying "Sync Error!".  What does this mean and how do I fix it?

Thanks a lot for any info or assistance you can offer.

What is the version of your camera firmware? I'm asking because the 1.01B was already dumped.

Then... The G7-based blinker is intended to work with serial port. It does not encode the firmware for ADC.exe recognition.

Yes, I noticed that this page states that the firmware for the SD1000  has been dumped, however, I have not been able to find out where I can download it from.  Is the firmware available download somewhere on the web? (And yes, my firmware is also 1.01B)

Also, thanks for the clarification regarding the G7 blinker.  I'll compile the other blinker software (blinker.rar from http://grandag.nm.ru/hdk/blinker/, right?) and see what kind of results I get.  If I can indeed download the firmware, then that would make things quite a bit easier, but nonetheless, I'm mostly going through all the steps (dumping the firmware, etc.) just for the fun of it :)

Thanks again for the info GrAnd.

The link was in one of the discussion threads on the dpreview forum. As I do not remember the old location, I've re-uploaded the file - SD1000 1.01B firmware dump.

Yes. This blinker is for sound-card dumping. Read this section in the wiki (and corresponding discussion) if you did not.

Thanks very much :)

BTW, would it be okay for me to add this link the SD1000 page in the Wiki so that others can find it easily?  (As I said, I'm new here, so I don't want to step on anyone's toes)

Yes. This blinker is for sound-card dumping. Read this section in the wiki (and corresponding discussion) if you did not.

Yep, I read both of those pages.  I guess I was just unsure of which software to use since the G7 blinker and blinker.rar were both listed in the link to the blinker software to use for soundcard input on that page in the Wiki.

Before I dive in, any thoughts on why CHDK was never ported to the SD1000 if the firmware dump was available?  Maybe someone knows of some pitfalls that I may encounter?

Thanks again :)

Hi Sokoban

I have also a sd1000 ixus70 but with firmware vers. 102a.
The dump is available at

http://www.zshare.net/download/63129850141872/

Have you start porting the dump?

Re: Help Dumping Firmware for SD1000/IXUS 70
« Reply #7 on: 09 / January / 2008, 22:24:44 »
I just got the SD1000 for Christmas and I absolutely love it, with the exclusion of some things that CHDK would add or change, so I'm so stoked about progress towards it.
Unfortunately I have no programming experience outside of web programming, so I can only test once binaries start to emerge, but test I will!
Also, how did you get version 1.02a firmware? Mine was bought around Christmas and has 1.01b.

Hi Wilson!
