There will be a dump shortly.  I have some space I'm gonna start placing stuff for my attempts.

@HarpMa: Is it possible for you to upload your current version to the svn-server? Because I think the sd1200 I am working on is similar to sd780.

I'll post it to my site but as for placing in svn i think it's too early.  Doesn't get very far yet.  But for reference I can make it available...

I do not suggest anyone other then a developer even look at this link.  It will ONLY show your a logo.

{modified - removed URL since topic top now includes it}

Also, don't do a make clean.  If you do then the stubs are likely going to break.  I have not followed multiple guidelines on the making of this.

[Off-Topic - but I don't know where to direct this question. Promise to keep it short.]

After the last weekend and quite a lot of videos I realized that there is no auto-focus while taking a video. I couldn't belief this and called Canon today. Support employee #1 supposed my cam to be defective and advised me to send my camera to a local hardware contractor. Contractor #1 told me that this is totally normal. Called Canon again. Support employee #2 confirmed this. And stated, that this is true for many/most Canon cams. I still can't believe this.
(Meanwhile I found the Video Parameter: AF key that might be a workaround)

Can someone confirm, that this cam can't auto-focus while taking a video?

Yes.
It looks strange but it's true and is clearly stated in Users Manual.
AFAIK it can be fixed for other camera models with CHDK.

I read the manual before I bought the cam. Didn't get that.

Now keeping my fingers crossed a bit more, while waiting for a beta firmware,

With my SD1200IS udumper is not working, because the sequence of bytes 0000 0000 0000 0000 0000 0003 ... followed by adresses greater than MIN_ADDRESS (firmware jumps) has not been found:
Code: [Select]
#define MIN_ADDRESS     0xFF810000
...
for (i=0x1900;i<0xF0000;i+=4) {
if ((*(unsigned int*)(i+0x34)==0) &&
(*(unsigned int*)(i+0x38)==0) &&
(*(unsigned int*)(i+0x3C)==3) &&
(*(unsigned int*)(i+0x4C)>MIN_ADDRESS) &&
(*(unsigned int*)(i+0x50)>MIN_ADDRESS) )
{
...
}
}Any ideas modifying the udumper to work with SD780IS? Then I would like to try it on my SD1200IS.

I never used the udumper for the SD780.  It may help to take the FW for the sd780 and look for the pattern of bytes around the functions required to fopen/fwrite/fflush/fclose   Not certain if you can perform them that early in the boot cycle but might be worth a try.  Note of course that the SD1200 will NOT have the same position for the functions.  Only the pattern might match.

For the SD780 I dumped the first firmware with the blinker program (ie serially blink the firmware to the LED)  For the second FW dump (8M version) I used the fopen/fwrite/fflush/fclose.
