IXUS 100 IS (Europe) / PowerShot SD780 IS - Porting Thread

Very sorry to be a pest. Is raw fixed, or will it be posted here when it is? Just don't want to keep downloading and re-installing until I know. 😳
Thanks,
Dan

@danstr - Nope not yet. Watch this thread and when it is it will be posted here.

O.K. Thanks Jason,

My bugreport with 878:

1: Switch from manual to Auto mode and back is not working. I need to turn off the camera, switch to auto mode, and turn back on.
2: When in auto mode, and the background of the AUTO logo in the upper left screen turns blue, the chdk osd font color also turns blue.

I know that AUTO mode seems not too important for chdk users, but I need it becouse of the WAF (Woman Acceptance Factor)

Is there any possible way to upgrade my camera to firmware version 1.00C?

And if I can't, then there's no way to use CHDK?

HarpoMa

1.00C is not available as a FW upgrade from Canon so the answer sadly is no. If anyone ever dumps the FW from a 1.00B then I will try to make a 1.00B version.

Well is there any way to take the .bin dump of 1.00C from the first post here and load that onto the camera? I guess there must be some sort of firmware upgrade utility? Sounds a bit risky, but maybe people have done it?

If not, is it difficult to make a dump of 1.00B? If it's not too complicated, I'd be happy to give that a shot.

HarpoMa

Nope on the firmware update method. It would be a bad idea to even attempt it.

As for dumps and porting I won't begin to repeat what the wiki so nicely says. http://chdk.wikia.com/wiki/For_Developers

It really is dependent on your skills. I will try to get a version of udumper working on the 1.00C and if I can then it likely will dump the 1.00B but no certainty or timeline on this.

I am focused on a stable beta build atm.

Harpo

lexluthor

I understand. I don't think I'll try doing the dump myself. I probably could, but it's probably not worth it, though those added features are nice.

Thanks.

Hey guys i got a problem. I replaced the v8 diskboot and ps2 and can load the chdk on my ixus. But i can not use override shutter speed. I tried everything but it will not work. Where is my mistake? With v5 it worked very well

disable overides to off/disable
include autoiso&bracketing is on
override shutter speed is 6.3
value factor is 1
shutterspeed enum type is ev step
but it only shots with standard settings like iso250 f3.2 1/60 it doesn't matter what the shutter speed is :S

i got stillt the same problem. i installed chdk with the script for macs. i can run chdk, but when i set the value factor of the override shutter speed to 1 it does not change the settings and shots photos with iso400 f3.2 1/40
is there a problem with the v8 diskboot.bin and ps.fi2 files?

HarpoMa

I would say yes given the fact that people are saying so. You might try the autobuild instead.

thanks the autobuild seems to work

I've had and 1.00B. I'm new to the project. The udumper does not work, thus I decided to dump it by blinking. I used a BPW 40 photo-diode (they had no 96 anymore). Because the blinker code did not worked for me, I've developed my own code.

I've succeeded blinking the firmware out, actually the beginning. As the battery went empty, it completely bricked my camera (impossible to power it on again). I've just received it back from warranty, but they upgraded my firmware to 1.00C. Thus I can not blink the rest of it. Here I'm posting what I have. I hope it's enough.

Otherwise, I'll be happy to help someone who wants to try it. I also had to learn everything since beginning.

I've dumped 6185989 Bytes, start a address ff810000 until ffdf6405. I hope I did it right.

I will post my source code as soon as I've cleaned it. I will also try to make udumper work.

IXUS 100IS 1.00B

HarpoMa

Thx. I will look at this and see if I can make a blind 1.00B version....Looks great but won't fully know until I get home tonight.

Sadly it looks like good portions are corrupt. Did you employ CRC checks of any sort?

I will try to create enough of a boot to read the FW and write to a file.....

Harpo

lexluthor

Thanks guys. It'd be great if you could pull it off. I'll keep checking in.

tsaitgaist

I did not used any CRC. I wanted to implement this feature a bit later. I dumped with the first version of my program, just to try if it worked.
I dumped the firmware in several pieces (the file in the previous post was the assembly of them)

here the originals.

Would it be difficult to get the required hardware from a radioshack to do the blinking for the 1.00B? I'm a total novice, but I can follow instructions, especially if you already have blinking code that works.

HarpoMa

@wasabi1023 - This URL will help answer that question. A lot of people have done a lot of things but this URL gives a nice overall set of methods. http://chdk.wikia.com/wiki/Porting_the_CHDK#Q._How_can_I_get_a_firmware_dump.3F

wasabi1023

I couldn't figure out the software part of the photodiode-to-soundcard method. I don't compile stuff on a regular basis (windows user), so I don't know how to get the environment correct for the source code to compile correctly. The readme.txt that came with the source is in some foreign language.

works! yeah 😁
