Thanks!

I've been waiting for the CHDK for the SD940 since I purchased it last year. Thank you for your hard work; it is much appreciated! Best of luck!

Firmware dump 1.03B

It's great that you're doing so much work on the SD940, thanks. I have been trying to get a firmware dump for my version 1.03B but no luck. I've tried the card tricks dumper starting with the DryOS and then the NewDryOS but nothing loads. Any help would be appreciated.

SD940 1.03B

Hi Waterwingz.

I tried copying your script into a DISKBOOT.BIN file on a card that had been formated via card tricks with the DryOS but no luck. Started the camera using the playback button, what am I missing?

Thanks, Larry


Larry : The script is for Canon Basic - DISKBOOT.BIN is the name for CHDK executable file, something entirely different. Store the script on your SD card with the file name = extend.m. You also need to format your card specially. Details are at http://chdk.wikia.com/wiki/Canon_Basic

SD940 1.03B

Waterwingz,

Thanks for the info, I'm making progress but still no dump. With the card setup as suggested and the camera in playback mode, when I press "FUNCSET" the screen reads:

SD940 Memory Dump

FF810000


done

but the card just has the three files, extend.m, script.req, and ver.req, nothing added to them and no new files.

Any additonal help would be very much appreciated.

Your 99% of the way done. Do you have "write protect" turned off or on ?

firmware dump SD940 1.03B

Waterwingz,

Yes, I had very carefully put the card lock on. In figuring out the card settings I had forgoten that part of your instructions. I have the dump, primary.bin 8,128 KB, but I'm not clear on where to upload it. Thanks for your time and help.

It used to be standard to post firmware dumps on dropio.com. They have stopped providing service so people seem to be using www.box.net or www.zshare.net. Both offer free accounts where you can put things for others to download. Post the link they provide to the wiki at CHDK SD940 Wiki Page and/or at the porting thread we have been using CHDK Forum SD940 Thread.

So, are you up to a little software development or are you pretty much stuck waiting for someone else to work with your dump ?

Stuck Waiting

Waterwingz,

I was challenged getting "SCRIPT" in the right place on the card but I do have a friend I'm going ask for help, he might be up for it and I think he'd be good at it. Thanks for your help with getting the dump, which I'll upload now.

SD940 1.03B firmware dump

I have a firmware dump for the SD940 1.03B at:

made with help by warterwingz, thank you for you help.

Dump looks good. Did a quick check and its not a match for the 1.03C dump - there was not much chance it would have been. Small offset in many addresses. Which means about 4 - 8 hours of work depending on how fast the porting person is ( I'd be out at 8 hours). Waterwingz 01:42, December 18, 2010 (UTC)

Offsets

Good to hear the dump is good, too bad it is so different. I'm surprised it is not a simple and supported change to go from the older 1.03B to the 1.03C firmware. I talked with my friend today and he is interested in helping. His birthday is Sunday and we are planning on buying him a Canon SD1400 which, although different will get him more interested in working on it, and maybe I can help.

I've been thinking about a way to automate the creation of CHDK for different firmware versions using the same method the original developers used for finding ROM addresses. Just not high on my priority list until I get the 103c version to what I would call a decent "Beta" status. Meanwhile, I can offer encouragement and moral support.

Automating

Automating the creation of CHDK for different firmware versions sounds like a great plan, I hope it goes well. Thanks for cleaning up the edit I did on the SD940 page for the firmware dump.

1.03B Version Status

Dont' know if you've noticed but there is a least one developer working on the 103B version now.

Success : Firmware 1.01A, 102C, 1.03B 1.03C now supported

Looks like we have pretty complete coverage for all the firmware versions in the wild now. Send me PM if you have firmware for the SD940 that is not yet supported.
