Firmware info

CHDK Specialties

This camera uses a touchscreen interface, so you cannot use the usual ver.req/vers.req approach to figure out the firmware version. Forum member zeno has written an application that can figure out your firmware version from the EXIF information in a picture you have taken with the camera: ACID .

Once you have CHDK on the card, to start it manually you turn on the camera by pressing the "play" button while holding the zoom knob to the left. This will add a "firmware update" menu item, which loads CHDK into RAM only.

The CHDK UI doesn't make much use of the touchscreen (which is good since all the menu items are tiny) but it does provide buttons down the left- and right-hand side to stand in for the physical buttons this camera doesn't have. In particular, the directional buttons are on the right and the "Set" button is on the left. This camera can use a large single-partition SD card for booting.
