Darren Hart, Intel’s Open Source Technology Center, gives a 5 step method to optimize Linux (image size, memory footprint and boot time) for embedded systems at Embedded Linux Conference Europe 2011.
Abstract:
Although embedded systems are less and less resource constrained, there is still a lot of demand for minimizing the image size, runtime memory usage, and boot time. The firmware, kernel configuration, hardware initialization, boot-time arguments, start-up scripts, and library sizes are all examples of things with a direct impact on your image size and/or boot time. There are several core processes involved with minimizing the size of an image, which has a direct impact on runtime memory usage and boot time. The focus is on configuration techniques that get you most of the way there and follow-up with source-level customizations that get you the rest of the way.
