SX100 IS

[martinF]

I have dissasembled the firmware dump and resolved the names of procedures. Can someone continue
with that, because I have no experience with DryOS porting and I don't own a Canon SX 100.

Hey folks...

Apparently mine is also a 1.00C unit.

Thanks to VMark for the SX100 specific blink package, adc/dec compiled and dumped easily under MinGW32. If the addresses are wrong blame him. The flashy-flashy capture bit took 2:15. I dumped it twice, the better of the two, adc generated 3 sync errors, and dec had no errors at all. Sound like a good dump?

Also for those that can't / won't compile for Windows, here are the binaries: sx100_adc_dec_win32.zip - 11kB. (VMark feel free to add these to your SX100 package, they are MinGW32 console builds.)

martinF - could you (or anyone with the tools & ability) disassemble this one also? IDA Pro Free doesn't support it.

 Cool some progress...

 What needs to be done after this ?
 If there's anything i can do to help...

Hoooray for you, Anaglyphic!!!!   I have 1.00C and was hoping someone would get a dump of it.  Thank you.

[VMark]

Hello all,

I will add Anaglyphic's Win32 console progies and chech the difference between 1.00B and 1.00C.
Nowadays I had no time to play with my camera/firmware, another home project got focus, but sooner-later I will came back.
Anyway, the firmware of A720IS is quite similar to ours or at least much more similar then S5IS's.

IDA Pro Free doesn's support processors other than Intel386+ as I remember well.

[Anaglyphic]

Hey VMark, glad you're still around...

heh  ph3@r mY m@d 5k1LL5!  re: including the firmware dump precompiled apps, what do you think about making a SX100-specific binary using the "universal dumper - one more idea" method? Not really universal if it's coded to a specific camera, BUT at least that way, people wouldn't have to buy a photodiode and hack up a cable, just dump it to that tiny 16M card that ships with the camera.

re: IDA Pro, yea I asked that in another thread. Oh well. Not that I have the ability anyway, but it makes learning easier.

Another version of the Sx100 1.00C dump made with sd card and 2/diskboot.bin (not the same binaries than the other 1.00c)

If this can help

Hi guys I have a sx100 1.00c, I wish I had the knowledge enough to modify my firmware, but I'mwilling to help in any way I can to get the thing done.
I want to have chdk running on my camera asap

[RuLoXP]

Hi guys. If the experts improve the firmware, will SX100 be able to shot in RAW?

[critical1]

Hi Has anyone made any progress with this lately?

[RuLoXP]

Could SX100 havs bracketing?

[xinwen87]

Hi guys. Is there anyone working on this recently?

[DemonLlama]

Just a nudge to show there is still interest in this model.  Doesn't appear that there's been any update in about 2 months

If I had the knowledge or skill to help, believe me I would!  Any effort by the community would be greatly appreciated!

[Bobsancho]

I also just registered to bump this thread I am hoping for a CHDK before my trip in July


What needs to be done right now anyway?

[Hacki]

Well. I'm also quite interestend in this topic. Bought the SX100 because of the nice price/performance ratio, well knowing there still is no chdk, but i was hoping it would be ported soon.

So, is anyone even interestend in working on this task? 
It's quite a nice cam, but with your CHDK, it would be even greater..
