There are all kinds of topics on boot optimization over on the Embedded Linux wiki:<p><a href="http://elinux.org/Boot_Time" rel="nofollow">http://elinux.org/Boot_Time</a><p>So I'm wondering if they just apply a set of these tricks given your circumstances. Notice that they guarantee a 50% speedup on <i>your</i> board, not that you'll boot as their example. The OMAP 3530 shown is a pretty fast chip. You also don't know what else they're skipping to get this speed.
This is awesome! I wonder how they achieved it. Normal boot times for Beagleboard are at least 15-20 seconds.<p>Perhaps it is using some sort of software suspend/resume functionality? I suspect initializing memory by copying an image directly from flash after U-boot starts up would be about this fast.
