Progress has been made?
I appreciate the work you are doing!
I know that you do for the spirit of sharing and you probably do not need but i'm going to pay 50,00 euros to anyone generates a working CHDK for firmware 1.01c!
I swear I do!
Thanks again!

[Finlandia]

I will donate another 50 euros!

Now that the OBC2010 Challenge is past, I can devote time to the 1.0.1c firmware again and I see that dhavalhirdhav is progressing, good to see that.

i've been waiting for this for a so long time. considering between continuing waiting or changing to a DSLR...

[dhavalhirdhav]

Hello everyone.. sorry for not showing up here sicne long time.. I was caught up with lots of work at office.. and was travelling.. I am back on this.. and will soon start putting more updated.

@openuas: any progress that you have made so far?

[openuas]

Honestly? No, same here lots of work to do... But this night, first time since long, logging into the forum, that is a good sign... No promisses, but I finally got my IR modded Cam working again. So now have Two working 200IS's.

Can boot CHDK, do get a boot message, then the Firmware crashes. Now it is time to undust and revive my Build environment on Linux...

[openuas]

So I've updated source CHDK to SVN revision 964. make clean then in make I'll get
reversebytes.S:11: Error: bad instruction `ldm r0,{R4-R11}'

Any hint?

[openuas]

i think i need this patch
http://chdk.neszt.hu/git/?p=chdk.git;a=commitdiff;h=cec4ed0d549e3d7872376b7bc03908903a4e84ef#patch12

[openuas]

@dhavalhirdhav, what does your

$ arm-elf-gcc -v

Give?

[openuas]

Today's progress. Installed Toolchain from scratch under Linux64bit and now CHDK build gave:

<< Leaving loader/ixus200_sd980
<< Leaving loader
>> Entering to CHDK
...
**** Firmware creation completed successfully 

JaY! On the the next steps...

[openuas]

Note:
Under Linux capitalization is important thus
>>make PLATFORM=ixus200_sd980 PLATFORMSUB=101C
is incorrect and should be

make PLATFORM=ixus200_sd980 PLATFORMSUB=101c fir

Mind the small c and not C in the end

[openuas]

Updated to SVN v966 and still :-) can compile via

$ make PLATFORM=ixus200_sd980 PLATFORMSUB=101c fir

Now onto the SD Boot issues...

[openuas]

Using GCC3.4.6 Crosscompiler on Linux 64Bit

$ make PLATFORM=ixus200_sd980 PLATFORMSUB=101c fir NEED_ENCODED_DISKBOOT=3

Press the Play button on the cam..This boots the firmware! I see the CHDK logo, then screen blanksnothing anymore...

but that is fine I will adjust main.c later, but now first of to getting the IRDA on Win7, Brrrr working inclusive helper scripts.
