Re: [Gumstix-users] Couple Quick Questions about Gumstix

[hypo <hyp...@gm...>]

u-boot is definitely a source of wait time. what interface are you booting
off? 

you can also shave time off by disabling features that you don't need such
as dropbear, httpd, bluetooth etc. i believe you can configure these via the
buildroot menu. are you aiming for a particular start duration?

thanks,
hypo
