Added the following two new firmware dumps to the drop.io - chdkdumps2 backup archive:

This dump apparently contains unspecified "stuff" left by unspecified tools, and so for all practical purposes is corrupted.
If a dump is not a byte for byte copy of the actual ROM, this should be mentioned somewhere.
Updated chdkdumps2 with corrected dump (16-Oct-2009).

I've blinked out 3 megs of firmware for the A1100 (0xffc00000 - 0xffefffff) but I don't have a drop.io account. Does someone want to PM me (on #chdk, I'm dch24) an email address to send it to? I'll probably have the last megabyte ready by then.

You can upload it to http://www.zshare.net/
Don't forget what the H stands for.

@dch24

No idea what you mean with "no drop.io account" ... you don't need one

However, for the benefit of people that find drops easier than zshare/other freehosters
here's one I just created

                                          http://drop.io/store_my_dump

no password required, guests have upload & download rights, i just disabled the delete feature

cheers,

wim

@dch24

thanks, looks good, took the liberty of renaming and 7-zipping it:

Yes, I've been working on getting a firmware dump for the past week. I used the firmware update (PS.FI2) method and a few adjustments to get the program running - started out with the udumper source code:
a. added "MOV     R11, #0" to entry.S before the branch to main
b. pre-padded the unencrypted diskboot.bin with 1636 NOP instructions - the code didn't seem to execute otherwise, either part of the file is stripped or the executable has to have a certain size.

I found the AF_LED at 0xC02380C3 by the usual method, strangely 0x00 must be used to turn it off (instead of 0x44). Originally I scanned 0xC0200000 - 0xC0200100, where I found the flash (that's how I knew the program was working) and proceeded to build an IR receiver (simple enough) and transmit/receive data from the device. You can get the firmware here: http://rapidshare.com/files/325920475/A480_100b_PRIMARY.7z.html (only 10 downloads available?) or here: http://www.easy-share.com/1908828842/A480_100b_PRIMARY.7z
pegahic has just found the a480 firmware
