I'm creating a project with raspberry pi and I need an "os" which boots in a few seconds when the power is turned on. The os has to have the following features:

  • audio driver (3.5mm)
  • c/c++ running ability with sdl library(no X server)
  • ability to mount usb (or an other way to transfer files)
  • ability to install few little packages when needed (apt)

I've tried to use buildroot but I've found it too hard for me.

  • Do tell us a little more: what task needs to come up in this time frame? – Marco Poli Jul 11 '14 at 19:54
  • What is a few seconds? Less than of the order of 30 seconds then it can't be done. – joan Jul 11 '14 at 20:00
  • You cannot have X up or even have a login or command prompt, but depending on what he needs he can have something coming up in a high priority init task way before 30 secs. – Marco Poli Jul 11 '14 at 20:13
  • Well that's good. If the OP's "few seconds" and "way before 30 secs" overlap the job is done! – joan Jul 11 '14 at 20:33

  • Arduino boot loads in less than a second. Get that. – Piotr Kula May 12 '15 at 09:01

The official OS raspbian will do, and if you use the new version / boot manager systemd it will be even faster.

But as mentioned this question is a duplicate How to improve boot time for Raspberry Pi?

I have similar problem and found that Arch Linux (and it was a first time for me - usually use Debian) to help me with boot time.
