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

danstr

Sorry for the noob question, HarpoMa, how and to what do I apply this patch?
Dan 😐:

HarpoMa

It is unlikely that you will want to use this. This would be for developers only. I will release a firmware on post #1 that you can place directly on the camera for actual use.

Thanks, and thanks for the quick reply. 😀 With the resolution on this camera, I am really looking forward to when it hits beta or final stages. I appreciate the amount of work that's been going into the port!

Since it appears zebra will take a lot more work than I thought I will post this 875 patch that adds SD780 support. Don't be surprised if zebra crashes.

The Ixus100 / SD780 1.00c port is in the CHDK trunk now, binaries are available from the Autobuild server. (SVN changeset #876)

@HarpoMa
To add your patch to the trunk, i've made some small modifications:
- modemap (main.c) line 50
- added notes.txt
- main makefile preparations for AB server
- camera.h layout, needs some more clean-up
- stub files added

danstr

Thanks for the BETA! Do most of the points on the first post still apply? ie: scripts, ignored stuff, etc?
Regards,
Dan

HarpoMa

I'll do an update of the first page this weekend with the details of work.

danstr

😁Much appreciated. Will try it out when I get home and have the camera in hand again. :lol

I downloaded the latest beta (877) today and copied onto the sd card. But after "firmware update" the screen goes black, and the chdk is not starting.

I need to remove battery to make the camera working again with stock firmware.

Prealpha version downloaded from post 1 is still working ok.

Great to see there's some more progress on this. Been using CHDK lots and looking forward to a stable version.

Same here.

Damned... If both LEDs show up, that means that the dumper found the BOOTDISK signature and also a function pointer that could be possible the WriteSDCard function. I compared the functions of the SD780 1.0C dump with the G11 functions, and there are almost the same. I am wondering that it is not working... 😐:

@ERR99
I have the 1.00B too and tried to dump it. I tried the DISKBOOT.BIN you provided and both LEDs lit up. I had formatted the card with a 20MB fat16 and filled it with zeros and only copied the DISKBOOT.BIN over. The md5sum of the FAT16 partition before and after it was run in the camera showed it was exactly the same 🙁

HarpoMa

I'll try the 877 myself and see what the deal is..... I confirm that it's not working from the autobuild server. I will check it out from svn and see if I can build a working copy....

@fe50 - I don't pretend to understand how this would occur but I'll tell you what I found.

The stubs_entry.S that you generated for the sd780 seems to have a consistent offset in their location.

The 4th digit is always off by 1. So for AllocateMemory 0xffa3df5c is correct but the file has 0xffa4df5c....

I think it's because I included some padding in the front of the firmware dump....My padding is exactly the size of the offset.

I have attached the working stubs_entry.S

Yes, that makes sense 😀
I used a dump from my collection, without a check, just let the build process create the stub files.
I'm on the run now, but i'll check & update the dump and commit the correct stubs to the SVN repository this evening.

Hello, I've tried the SVN Autobuild:

Tried out the Override shutter speed with 128s value and my yard was almoust clear as day with ISO 80 😁 Thanks !
Tried TV bracketing - works like a charm, but still little slow when goes around few loops...
ND filter - OK
etc.

Bugs:
Video shot with CHDK shows as "Unidentified image" in Preview mode, but computer plays it normally...

DNG files turns out like this:

In the menu, next to OSD parameters sometimes CHDK shows this:
[ 6528 = 0x00080006 ]
[ 6512 = 0x00000000 ]
[ 6496 = 0x00000000 ]

Nothing more for now...
Good luck, bye!

@HarpoMa:
SVN updated with corrected stubs_entry.S, also replaced the sd780 1.00c dump in chdkdumps2 with a cleaned one.

I tried the 878 build, get the same type of colored distortion in the raw files, tweaked the ult_intvl script because the parameters could not be saved , but was able to get bracketed tv working with custom timer. The jpg files are definitely bracketed by 1 ev which is what I shot, but no joy with the raw. Haven't tried motion detection yet, but bad_pixel.lua worked without any adjusting. Raw was working in the past, I remember getting some really nice sunrise shots, don't know what's changed there. I also get the numbers flashing but only while moving up in the menus, doesn't happen while moving down.
Looks promising, looking forward to a raw fix.
Keep up the awesome work, HarpoMa
Dan

Raw file issue confirmed and I now know the issue (Seems I left my head somewhere else) - Movie issue doesn't appear for me. I see a regular image for mine. I'll see what I can see and get back to you.

I'll do some more qa for a release the minor patch.

I'm having a problem getting this to work.

I have an SD780 with GM1.00B.

I downloaded this file
ixus100_sd780-100c-0.9.9-878-full_BETA.zip
unzipped it and put it in the root of my FAT16 formatted card.

I power the camera on in playback, I hit menu, I do a firmware upgrade, but, at that point, the screen goes black and nothing happens until I remove the battery.

Any help?

Thanks!

There's no 1.00B CHDK for your camera until now 😉

Wow, that stinks. So I have an older firmware in my camera?

There's no way to get CHDK to work on it?
