Thank you Neszt for your remarks, so I have to make some adjustments to my RS232 converter.
I did the dump twice and I got 2 identical files (checked with fc);
What program do you use to check the CRC ?

I used dec.exe in the http://chdk.neszt.hu/blinker.zip which reads the "dump" file as input and generates "dump.dat" as output. I saw the very begining of the file and i supposed that the dump is in that format.

xavan: was there anything in particular you had to do to get the camera to recognize the diskboot.bin?  I'm starting to think I should just find an adapter so I can use cardtricks on my card.  Is that what you did?

Guys,

I just want to wish good luck with your endeavor and to hope with all my heart that you will succeed quickly with the GM 1.02B firmware. I'm also waiting for it and I'm very impatient to use it... :-))

Thanks!

Me too, I miss all the features of of CHDK that I had with my previous Canon when using my new SX20.

@xavan
congratulation for "blinking-out" the new firmware. :-)
What is the next step? Disassembling the code?
I tried to disassemble the dump file with idafree version 4.9. on windows xp. But i can't choose an arm processor?

What kind of disassembler with arm support do you use?

Bye Frank

Hello & welcome, Frank !

You need IDA Pro - the free version don't have ARM support.
