Canon Powershot Digital ELPH SD450 / Digital IXUS 55 / IXY Digital 60
This is a 5.0 megapixel compact camera that runs the DiGiC II image processor chip. It may be possible for the CHDK firmware to be ported over to it.
Firmware Version
Canon DIGITAL IXUS 55 P-ID: 30FF PAL Firmware Ver GM1.00B No error Aug 3 2005 13:53:21
Camera ID for pakwif
30ff hex = 12543 decimal
01000000 hex = 16777216 decimal = version 1.0.0.0
So:
- pakwif PS.FIR DISKBOOT.BIN 12543 16777216
Useful Constants
/* LED addresses */
- define LED_PWR 0xc02200E8

- define LED_RED 0xc02200DC
- define LED_YELLOW 0xc02200E0

Firmware Dump
Version 1.00B will be extracted using the "standard" Blinker method. I used a standard phototransistor and basically the following circuit:
I was not able to decode the signal without errors using the fastest transfer speed. Therefore I had to change the blinker FW to the slower speed seetings. Using the AF LED I was then able to get a clean signal.
Important: The first dump was wrong, because the starting adress for firmware in the Ixus Models is 0xFF810000. I will therefore have to restart the dump and will post the files hopefully tomorrow.
