Hi all,

I recently started to look a bit into the dump file...
It seems, that for analyzing mostly IDA is used here!?
I wonder if everybody has access to IDA pro...it is a bit expensive for just hacking a 180Euro cam  :o
The freeware version does not seem to support ARM...is this right!?
Is there a useful alternative...may be less powerfull...

...have fun...

Michi

Interesting timing - I've been working on something that might be useful but its only been shared with a few people right now. It an early version and not very well tested or documented.

Wiki page is http://chdk.wikia.com/wiki/CHDK-PT_:_A_tool_for_porting_different_firmware_versions_on_the_same_camera

If it looks interesting, send me a PM and I'll send you a download link for the pre-release.

Hi waterwingz,

for sure I'm interested in the tool. I'd like to be beta-tester as long as you can stand my dimwitted questions.

Actually I try to figure out the best tool setup, IDA is much too expensive for my use.

So any supporting tool is welcome and will be part of my evalution.

I sent my Email/Skype address in a PM.


...have fun...

Michi

Michi, nice quadrocopter. I'm in the model helicopter hobby too. I have a Protos 500 and I made a custom camera stand for my old camera but I had big problems with high frequency vibrations. I will have to modify my old camera holder to fit the SX220 in it and see if the image stabilization from the new camera will make the difference.

Hi,

I'm quite interested in your experiences.
I've done some early experiments with a "key chain cam" and had horrible vibrations in the video.
I assume, that this was related to bad mounting and very low weight of the key-cam...
I read a lot posts, recommend to disable the IS in the camera for copters!?
I hope for you, that this is wrong...and for me too, because the IXUS220HS does not have the opportunity to disable the IS in the standard menus.
I've not checked if this is possible with CHDK...!?

Afaik my cam has "only" an electronical IS, so this may be easy!?

...have fun...

Hi,

I'd start to setup a trunk for the IXUS220HS. Any advice which existing port may be the best master version.

How can I access the SX220HS as template? It still is not available in the trunk!?

...have fun...

I would like to use CHDK-Shell to compile.

Can anyone help me introducing a repository to the actual SVN-Trunk?

...have fun...

Hi michi,

Funnel seems to be using CHDK-Shell, so I suggest you download his latest source release.

hth,
