Canon Powershot Digital ELPH SD450 / Digital IXUS 55 / IXY Digital 60
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

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. I repeated the procedure twice to verifiy that the results are ok and obtained the following dump:
Ixus55_dump_1.00b.zip - 1.35MB
Repeating the procedure for another Ixus 55 with firmware version 1.00c resulted in the following dump:
ixus55_dump_1.00c.zip - 1.35MB
Beta version of CHDK port for firmware 1.00B
The following code contains the next beta version of the CHDK port for the Ixus 55:
I compiled this version on a Mac running OS X 10.4 using the ARM toolchain from here
Now everything seems to work more or less, especially Raw-capture as well.
I opened up a corresponding discussion thread at the CHDK forum here.
