    There aren't any more leds in the range up to 0xC0220100, but I could try to search for leds in a bigger range.

    I tested the new udumper yesterday, but it didn't work.

    I don't think you need more than the AF LED for dumping the firmware. I hope you have an oscilloscope though, you will need something to get the right timing.

    I just begun to work on it.
    I just setting up the cross-compiler environment on a debian-lenny to make the correct files to copy to sd card, but it seems to be more complicated than i expected.. So if anyone already made the required files, these would help me (hi, jan :-) ).
    The blinker hardware is ready in the meantime, so i only need the right prepared sd card with the blinker program.

    It was not trivial to me, that starting the cam in play mode different, than starting the cam and switch to play mode. Ehhh..

    Finally i success setting up memory card. My gren AF LED is blinking, sending the fw. It's time to grab with my new blinker hw via RS232. :D

    I got the first sx20 dump file, but it is definitely worng because of wrong delay values. I am not professional in this, so any help would be appreciated.

    There are two delay defines in the blinker's main.c:

    #define DELAY232 132
    #define DELAYGAP 100

    I don't know what delay should i modify? Only one, or either together?
    How to determine the right value(s) with an oscilloscope?
