I just wanted to offer some words of encouragement to all of you on the S90 firmware dump.  Thanks for giving this a serious effort! 

The S90 is a fantastic camera with a lot of capabilities.  But CKDK would allow for correcting one big deficinecy that I am not happy with - that is the low bit rate on the video.

Thanks!

OK, this is the finished dump from address 0xFF810000. All addresses from 0xFF800000 to 0xFF810000 were value 0xFF. All addresses after the end of this file are value 0xFF as well.

EDIT: New dump, 0xFF810000 - 0xFFFFFFFF, previous one was flawed

Guess I should grab IDA and take a look at things, but I've never coded for ARM before :)

It would seem RapidShare are not too keen to allow free downloading at present.

You could try ZShare.net.

This does not look right in IDA.

The downloaded ZShare file is 1,306 KB.

EDIT:

That is better, I have downloaded again.

Well, that kept IDA occupied for quite some time.

Seems O.K.

For the benefit of future porters, could you describe each step as you proceed, including the blinking procedure ?
