Revision as of 18:05, 1 December 2011

The table below is color coded to show the status of development work on porting CHDK to different cameras. If there is some work being done to port to a particular camera, there should also be a link to a camera-specific development page.

The page also has links to articles which could be useful if you want to participate in the development process.

Legend
  • Black - neither original firmware nor firmware dump is available
  • Red - Camera has responded to something on the card, but a firmware dump has not succeeded, current udumper code does not work on these cameras.
  • Blue - either original firmware or firmware dump is available; porting is needed
  • Magenta - A developer has started the porting process for this camera AND an alpha or early beta build with a limited feature set is available for testing
  • Green - A port has been completed on one or more firmware versions for this camera, the sources are in the trunk and the binaries are available from the Autobuild server.
  • Cyan - There is no active development of CHDK for this Camera, but there is an active development and a working version of Magic Lantern, which is a widely accepted CHDK replacement for these cameras.


Note: the porting process entails:

  1. get the camera to somehow respond to something on the card. (cameras in Red)
  2. using the process that got you step 1, and some electronics, read out a copy of the existing firmware (e.g., dump the firmware). (cameras in Blue)
  3. analyze the firmware, find out where key routines are.
  4. modify the source code to add the locations of these key routines
  5. compile the software and CHDK runs on the camera in some limited state (cameras in Magenta)
  6. After all minor bugs are fixed the build can be added to the trunk (cameras in Green)
