This guy has been doing some work on getting a raspberry Pi to boot fast: https://github.com/gamaral/rpi-buildroot https://github.com/gamaral/rpi-buildroot
Demo: http://www.youtube.com/watch?v=4Fjfqz6FxC8 http://www.youtube.com/watch?v=4Fjfqz6FxC8 It seems to be 3 to 4 seconds.
It is however for a specific use and I don't know how polyvalent it is.
- joezydeco 13y agoThere's a great case study and documentation at eLinux.org. This guy stripped a Renesas SH7724 boot-to-UI from 19.44 seconds down to 0.77. http://elinux.org/images/f/f7/RightApproachMinimalBootTimes.pdf http://elinux.org/images/f/f7/RightApproachMinimalBootTimes.... The tl;dr is that there's a lot in the kernel you can disable or strip away if your target system doesn't need it. The section on optimizing your application for block-oriented storage (like NOR flash) is a great one too.
