Hi, im also interessted in getting a working port for the sd880.

would be fine if seth could report how far he is with the port. Or where the Problems are, so that we could help.

Sorry everyone, I have been extremely busy between work (we've had way too many people laid off in IT so I'm basically doing 3 times the work now) and a trip I'm planning (the whole reason I got this camera).

I did make some progress finding the numbers in lib.c but I'm at work right now. I'll post what I have when I get home.

I really do plan on continuing work on this, I've just been distracted and I'll be out of the country (and away from computers hopefully!) from the 11th to the 27th.

Here's what I have so far.

Thanks for the update Seth, your efforts are very much appreciated.  With the CHDK and the fast continuous 1.4 fps plus the Servo AF, this camera can almost be like a mini dslr.....I said almost. :)

Does anyone know if we can increase the resolution with CHDK for video mode to HD from the standard VGA 640x480?

I am new to chdk and hope to start programing but  am not good enough yet.  For those of you working on this project, thank you! :)

Another CHDK-n00b here. I'm going to try and see if I can help with the port. Reading the firmware code and programming shouldn't be a problem, but I'm currently missing any overview of what precisely needs to be done (and is done).

The first thing I would like to establish is a (detailed) list of the various tasks (and subtasks) that are required. This way it should also be easier for other people to help by picking one of the (sub)task they think they can do.

Any help with making the list is welcome (as are comments).

There are many "how do I get started" threads in this forum.

You should also read the development section of the wiki.
Don't forget what the H stands for.

A bit of a status update:

I restarted the port using the SX10 port and incorporating the changes of sethv. I also have a list of all the things that are done and still have to be done. If there is interest I can share it and the same holds for the sources (both require a bit of cleanup before posting, though). In short, there are some constants in platform/ixus870_sd880 that need to be checked (especially the keymap) and most of the assembly code in the platform/ixus870_sd880/sub/1.01a has to be updated where needed. I'm currently working on boot.c myself.

With a bit of luck I can finish most of this myself today, but help is definitely welcome. What is needed to help is the dumps of the ixus870 and the sx10 (e.g. in IDA; see wiki) and the sources of sx10. I'm hanging around in the #chdk IRC channel if you want to talk to me directly.

After finishing the assembly code and fixing some constants, I have been able to start debugging. Currently all but one CHDK tasks seem to run fine (mykbd_task being the odd one out).

There are still a bunch of constants that need to be fixed. Some of them should be easy now with the on-screen debugging output of what is already running. There are also a couple that require further investigation too make sure they are the right ones.

I hope to have a first "beta" version by the end of tomorrow (but I could also be clueless about what is yet to come).
