Hello das U-boot enthusiasts,
I've been working on a buildroot OS for the embedded device my company is developing. Currently I'm looking at optimizing the boot process to be as fast as possible. I've read a bunch of articles about snapshot booting and fixed snapshots to improve startup time. One paper in particular ( Hiroki Kaminaga , https://www.kernel.org/doc/ols/2006/ols2006v2-pages-25-34.pdf ) references the use of the command "bootss" which is supposed to be implemented in U-boot. I've looked in my instance of u-boot and in the compilation options of buildroot (for U-boot) and can't find anything that references this command. Also, I can't find any documentation regarding this approach of booting with a snapshot. Is there someone who had some experience/knowledge concerning this who can point me in the right direction? Thank you for your time.
Best regards,
Jori van Dam
Met vriendelijke groet, With kind regards,

I suggest to take a look in buildroot rockchip implementation. A px30
device can boot in around 10 seconds to emmc including persistent
splash screen, wayland and application. You can have it faster
if you can implement falcon mode.
