Hi,
I know that there is no chdk release for this camera, but can i use A430's or A450's chdk releases with this cam ?
Since these are same series models, i thought it may be possible. I just need manual exposure control and raw mode for this camera, video features are not so important for me. Thanks.

There is zero chance of a build for any other model working on the A420 I'm afraid. There is a dump for the A420 (the first step in producing a port) but no work has been done on it for a year.

Only software. Some assembly language is required, but if you understand the principles, the arm documentation is sufficient for all the ARM specifics.

See http://chdk.wikia.com/wiki/For_Developers and especially http://chdk.wikia.com/wiki/Adding_support_for_a_new_camera

Looking at the a420 page, it appears that some work has been done. A digic II/vxworks camera should be pretty straightforward, although some of the really old ones have a few oddities.
