I am new to the world of CHDK and having settled on either the SX260 or SX230 for my new camera to buy soon, I was curious what the usual time frame is for getting the CHDK in place, so to speak. I would love to use the newer camera on my upcoming summer vacation, but I will purchase the SX230 if you guys think that the new firmware might not be cracked.

I would love to help the process in anyway I can, however I only have very very basic programming knowledge.

Thanks,
Mike

I think this pretty much covers it :

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

Go with the sx230.

Not at all.  They were fair questions and ones that come up a lot.  Navigating CHDK documentation is not for the faint of heart I'm afraid.  I actually thought some more about  my suggestion to go with the sx230 - its free advice so take it for what you paid for it.   In the end, its up to you - the sx260 will most likely get ported some day.  Just a question of you getting luckly with your timing.

Hi schapman, with an sx260 now, I will help with the port

I ported the sx210 so may have some similarities, how far did you get?

@waterwingz or any other guru
is there a new CanonFW_DryOS_A-Series.sig  for IDA ?
and what is the latest chdk.idc and others finders for this new cams?

Thanks

@schapman

Did you find the LED_PR  address for \loader\sx260hs\main.c ?

Or we need to change it for handling  your three adresses?

Sorry - I'm not a IDA user.   But recent chatter on the CHDK IRC channel suggests that the various IDA script files are not going to play well with the newest DryOS and the code it moves down into RAM.  That's all I know.

I don't think there is anything new for a long time. The existing ones will be quite broken with the code copied to RAM.
Don't forget what the H stands for.
