Linux Fast Boot on i.MX6

zsmite — Sat, 20 Feb 2016 05:04:46 GMT

my board is a forlinx OKMX6Q, which is very similar with SabreSD. main storage device is emmc. following the concept of [ Linux Fast Boot on i.MX6 Sabresd Board ] link: Linux Fast Boot on i.MX6 Sabresd Board , the board can boot within 2s with a camera render to display. the BSP version is 3.14.52 1.1.0 GA.
