Porting process[]

→ Porting the Ixus 75 / SD750 is done, CHDK for the SD750 is included in the official source code tree (trunk).

As of June 2008, a beta CHDK port is available for firmware 1.00b, 1.01a and 1.02a [1]

Development for the other firmware revisions can be monitored in this thread:

Note about the different Firmwares[]

Cameras with the 1.01a firmware can/must use the CHDK version for 1.01b - the autobuild already just copies this, so when you have a 1.01a cam you will find YOUR version in the autobuild. Development is happening in the 1.01b tree, then compiled and just renamed for the 1.01a people.
