Hello. Does exist a scheme of CHDK starting (function calls...,...)
Or (block)diagram? I would like to understand the entire process of starting beggining with copy_and_restart. How the camera does load the diskboot bin and process it?
Is something like it available? If it was a graphic it would be perfect. Do somebody know the process? I have something read in the section Dryos- some success. Thanks much

I too would be very interested in this information. I am trying to learn how my camera starts up and loads chdk code, how the tasks get started etc.

I'd also like to know more about the memory layout.

Is there any documentation on this?
