Ok thanks x286 and chr for making it easy on me. So I tried.

However the cam boots up normally so it seems it doesn't work on mine :(

Now what do we do?

yes it did show that. I must have done something else wrong.

Now i tried a second time. Now it doesnt start up or do anything. That's ok right?

So I waited 20 secs and took card out again. The empty.dum is the same size as before so im not sure it worked..

anyway here it is RapidShare: Easy Filehosting

The dump seems to be ok. I stripped leading and trailing garbage, so its much less data to download, ready to be disassembled with IDA:

Indeed it looks like a real dump. The first step towards porting the A590 has been taken. That dump should be added to the wiki. (it however seems to be offline right now)

Thanks to everyone involved! Hopefully we can find someone who can actually port it too.  ;)

Great!
I hope someone who can do something with it will come along soon.
In the meantime there's opportunity to practice the basics with my cam :)

The dump seems to be ok.

It's shifted up by one byte, thus I had to remove the first byte before loading it into IDA. You may consider changing the file.

Result:
Signatures apply, idc-scripts find functions and basic startup is what I expected. The dump is ok.

Note: The dump ends early. Everything needed for porting is there, though.

Note2: Firmware Version 1.01B

Cheers.
