link> CHDK FAQ : My camera isn't ported yet

If you can read through the docs and get a firmware dump,  that would be a great place to start.

Save it on an online file share  ( e.g. www.box.com ) and post the link here ?

TIA

I just bought the 2500 today.. Went through the steps listed in the wiki. Turns out that my firmware version is 100a too.. Also, the next step would be to get the LED addresses. Is there a way to do that without the photodiodes/transistors? I couldn't find a way to do that with the dumps.

To get the LED address, you should run a Canon script which scans possible LED addresses. There is  sample script posted here: http://chdk.setepontos.com/index.php?topic=6972.msg78852#msg78852

Instructions of how to run Canon Basic Script: http://chdk.wikia.com/wiki/Canon_Basic/Card_Setup

EDIT
I started A2500 porting thread.
