Previously we spoke about our efforts to optimise the boot time of our Snapper 9260 module, getting it down to ~5s. Having done a bit more work on the hardware, software, and moving to the AT91SAM9G20 module, we now have this down to ~3s from initial power applied. This is a full boot, with peripherals initialised, reading from NAND Flash for its root filesystem etc. Having used a lot of embedded systems over the years, we are very pleased with this result, as it certainly out performs all the similar devices we have seen in its class.
