Introduction

This page collects resources and techniques for testing a CHDK build or port. See also Debugging

this is a work in progress, please expand!

General guidelines

The CHDK User Manual gives an good overview of many features. Working through this list and verifying that your port matches the documented behavior.

Note that many CHDK features are poorly documented or poorly defined. When in doubt, consult the source.

Testing overrides

When testing overrides from script or the override menu, it is important to know Canon firmware displays and EXIF information may not reflect the actual value used. The functionality of the override should be determined from the image.

Testing with scripts

There are some scripts which exercise various CHDK capabilities
