No, a810-100b-xxxxx is only valid for firmware version 100b

a810-100d-xxxxx is only valid for firmware version 100d.    Only this files will work on your camera. 


In a few days I'll post a new version for 100d.

Hello nafraf
I downloaded your a810-100d alpha  software posted yesterday and installed it on my SD Card and tried it on my PowerShot A1300 and I suspect the porting & firmware are both the same Cameras only the A1300 has one upgrade from the A810 an optical viewfinder. I find the software also boots up and loads on my a1300. My A1300 has the same 100d version no so I guess both cameras are the same except for the Optical Viewfinder on my A1300 which makes it a very nice Camera. I havn't had too much time to play with the software there is a few minor glitches with the OSD on the main menu the framing square wipes out the letters and you move around the focus Square through they come back. If you need a firmware dump If I know a little more what I was doing I could get a firmware dump from my Camera. I hope that helps thanks very much nafraf
Regards
Gerry

Hello Gerry, That's too weird, but it's very interesting :)  I'd like to have access to the a1300 firmware dump to compare both.

Here you can find information for firmware dump:  http://chdk.wikia.com/wiki/Canon_Basic/Scripts/Dumper
Thanks

Hello nafraf
I went to that scripting page and I see a lot of text I don't really understand how do I get the firmware dump done on my new A1300. I already tried Cardtricks software it did not work for me. Did you have to use the blinker Nafraf? Can you add a few simple files to the SD Card and get a dump. How did you get the dump out of your a810. I might have made a great discovery Canon uses the same firmware in more than 1 camera.

You don't need any blinker,  it's possible to do the firmware dump using only a SD-CARD and the dumper script.

First, SD-Card should be prepared for running dump script. After that and you need to copy  the code of  universal dumper script to a file named "extend.m", in sd-card.  Then turn on the cam with PLAY button and press FUNC.

Detailed instructions for prepare SD-Card are in overview section of http://chdk.wikia.com/wiki/Canon_Basic/Card_Setup.
If you are using windows, check instructions using EOSCard and ignore scripts in CHDK and *nix section.

Similar case was seen with sx240hs and sx260hs models.

One small caution - sometimes the font color used with the Universal Dumper script does not show up on the LCD so it will look like nothing happens when you press the FUNC button.   Check the SD card for the PRIMARY.BIN file - it might be there even though nothing showed on the screen.

Finally, AF during video recording is working.

I used this hint:

Great news, I found a way to solve the AF Scan crash. I used DoAFLock() instead of MakeAFScan(). I was experimenting with UnlockAF after MakeAFScan to see what happens and tried also DoAFLock and found it. Look like it has the same functionality and doesn't crash when zooming.

I added an entry in stubs_entry_2.S with name MakeAFScan but using DoAFLock address.  Is it OK? or do you recommend other workaround?
