  • Page 7: Boot Loader

    Chapter 2 Introduction The i.MX 6SoloLite EVK Linux BSP is a collection of binary, source code, and support files that can be used to create U-Boot boot loader, Linux kernel image, and a root file system for i.MX 6SoloLite EVK development systems .
  • Page 8 The rootfs.ext2.gz file system includes Freescale specific libraries and gnome GUI. It can be mounted as NFS (see Setting rootfs for NFS), or its contents can be stored on a boot media such as Secure Digital (SD) card. i.MX 6SoloLite EVK Linux User's Guide, Rev.
