ELPH 110 HS (IXUS 125 HS) Porting Thread

Hi everybody,
I am new to CHDK development and just starting to get acquainted here.  I've used CHDK a little bit on my S95, and now I would like to get it working on my new ELPH 110 HS.  Seeing no prior work on this camera here, I've decided to give it my best shot.  I have programming experience, mostly C and Python, no experience with disassembly, etc. but I am willing to learn.  I am using Ubuntu for development, so I will have to figure out what tools are available for all this.

Here is what I've done so far:

I tried getting firmware version with ver.req/vers.req using FUNC/SET+DISP as well as every other button combination I could think of, but nothing seemed to work.  Then I tried giving an image to ACID, and that gives me firmware version:  100d

Used the univeral dumper script to dump the firmware.  The log file says:
Started
FF000000 dry
done
The dumped PRIMARY.BIN is here:  http://ubuntuone.com/13tgUTl51dOVupayl3Rxcs

Started a wiki page:   http://chdk.wikia.com/wiki/ELPH110HS

I'm kind of short on time the next few days, but hopefully will have more time later this week to work on it.
Any help is welcome. Thanks!

Jim

Welcome.

If you haven't already, be sure to check out http://chdk.wikia.com/wiki/For_Developers especially  http://chdk.wikia.com/wiki/Adding_support_for_a_new_camera

Assuming you don't have the appropriate version of IDA, you'll also want to look at http://chdk.wikia.com/wiki/GPL_Tools and possibly consider running http://chdk.wikia.com/wiki/CHDK-PT under wine.

You can sometimes get more real-time help in the irc channel, #chdk on freenode.

You will also need a properly configured ARM toolchain.

From the dump, this is a DryOS R50 cam. This new OS version has some differences from earlier versions. The sx260 is the first dryos R50 port, so you will want to follow that thread http://chdk.setepontos.com/index.php?topic=7889.0

Hi there,

has anyone gotten into CHDK development for the IXUS 125HS / ELPH 110HS yet?
My coding skills are limited to turbo pascal/delphi, prolog and huskell which only adds to general code understanding. But if someone would guide me, I might be able to contribute to the IXUS 125HS port.

cheers,

Standard disclaimer at this point :
link> CHDK FAQ : My camera isn't ported yet

Other than that,  the links reyalp posted above are a good place to start.   First step, in addition to reading through the info above, is to setup a build environment (try CHDK-shell on Windows).  If you can rebuild other versions then you have a starting point.   It wasn't pretty, but there is at least one port "completed" but someone who claimed to have no coding experience.  So you are off to a better start.

Hi, I started a blind port of this camera, fw version 100d.  It is not complete, but you can use it to start.  The files are available here.

I'm also interested in CHDK for the IXUS 125HS / ELPH 110HS, but haven't got the programming skills to help.
But i managed to do a Firmware dump for version 100e:

I can try to continue the port,  but I need your help for tests.
