Re: Battery powered raspberry pi
One of the last off-season tasks for FIRST 1296 is playing with the PiCam so I happened to be looking into quick boot times. Some solutions for booting quicker include using a class 10 SD card (faster transfer rates), compile kernel to use hard-float (faster math), remove all necessary services (less to start at boot time), remove unused kernel features (smaller kernel loads are faster), no DHCP (no searching for an querying DHCP servers), alternative user space startup schemes (other than sysV style), quiet console during boot (less time printing startup messages), customize/trim library contents and busy box features, etc.
The Pi runs embedded Linux and there are huge repos of advice out there to optimize the boot time. Many folks are booting Pis in 10 seconds, sometimes less. I'll post 1296 results here in a couple/few weeks.
