<CHDK

Background
The Canon PowerShot A650IS is generally available as of September 2007. It is based on the Digic III platform. As of this writing, the G7 is the only Digic III based camera with a version of CHDK available. This page is holds information intended to assist in porting CHDK to the Canon A650IS camera.

For more information about the US version of this camera, see [this page].

Firmware Version
Per the CHDK FAQ 1.3

Power on in PLAY mode with ver.req file on SD card, press and hold FUNCSET, press DISP reveals the firmware version. For example:

Canon PowerShot A650 IS

P-ID:315B NT D

Firmware Ver GM1.00D

NoError

Jul 6 2007 12:41:33

subsequent press of DISP (while still holding FUNCSET) reveals (for example):

Adj Ver.006.005

subsequent press of DISP (while still holding FUNCSET) reveals (for example):

IS Firm Ver. 3.01

IS Param Ver. 3.00

If you power on in PLAY mode without ver.req on the SD card and press the FUNCSET and DISP buttons simultaneously, the screen shows:

Firmware Ver. 1.0.0.0

[ OK ]

Subsequent presses of DISP have no effect. One must press FUNCSET to clear the screen (i.e. answer the OK).

Firmware Update Prompt
The A650IS does not seem to follow the firmware update prompt of previous A series cameras. As yet, the sequence to reach the firmware update prompt has not been determined. See CHDK FAQ 1.7 for details.

Language Interface
Power on in PLAY mode with ver.req file on SD card followed by pressing FUNCSET and MENU simultaneously brings up a menu where you can change the language interface for the camera. Use the direction button to select the language and press FUNCSET to accept the selection.

Other button sequences don't seem to do anything.

Known Problem
A potentially serious problem with early A650IS production units has been discovered. It is expected that Canon will issue a recall/repair notice for affected units. See [this article] for more information.
