s80 anybody?

[jeff99]

Hi

New to the board. Have a Canon s80 and I'm desperate to get a hack to enable me to use RAW - anyone done one for this camera? Have tried search and found nothing

Thanks

Jeff

Doesn't look like there is then. Never mind, only thing I can do really is to buy a G9 I guess! Never mind!

Thanks anyway,

Jeff

I own a Powershot S80 as well and was wondering if people are still working on getting a hack for this camera?  thanks.

Good Day Guys,
I just got informed about CHDK project, thanks to Slashdot. It seems that CHDK guys already spent impressive effort on the custom firmware. I own Canon S80. its a nice camera and it definitely worth of porting the firmware to this platform also. 

I think we can use this post to sync about S80 porting progress, since this is the only post related to S80.

I just got the version information from mine.

Canon Powershoot S80
P-ID30FA NT
GM1.00F
E18

adj ver.004.019
Subcpu ver 2.02

Let me check the website and previous posts in detail to see what is required to start this porting progress and how we can assist the developers to have S80 supported.

Regards.

Yep, thats why I wanted to be in sync with the other S80 owners that deals with CHDK, otherwise there will be more variants of the firmware...

P.S: upps, it seems that I worked to much with CF cards in the office in the last 2-3 weeks for a hot project... I did a sed 's/CF/SD/g' in my previous entry..thanks Jucifer for pointing the typo

Ok.
at last I found some time to continue...

I got the CHDK source code... we are lucky since someone already dump the firmware and its available at zSHARE - primaries.bin.rar
 

As far as I can see  to compile the code I need to update
~/CHDK/src/branches/grand/platform/s80/sub/100g/stubs_entry_2.S
file with the correct addresses of 3 functions which are missing for S80. There will be more to do but lets start...

VbattGet                     ---> 0xFF82C2B4
free                            ---> 0xFFB05400    // its interesting that the function name referred is mempartfree
kbd_read_keys_r2       ---> 0xFF82737C   // not 100% sure..

lets deal with makefile.inc

I would love to help out with this, seems like a fun project.  So far I've got the chdk dev environment up, and im in the process of procuring an arm disassembler.  My only assembly experience ever has been a class i took at school dealing with the HC12 68000k microcontroller, so im in for a bit of a learning curve.  any suggestions for reading material outside of the wiki?

[cymsin]

So has the s80 been abandoned again? It seems every few months someone puts some work into it, and then abandons it until someone else comes around to do the same thing.
