This script will create a bootable SD card from custom or pre-built binaries.

The script must be run with root permissions and from the bin directory of
the SDK

Example:
 $ sudo ./create-sdcard.sh

Formatting can be skipped if the SD card is already formatted and
partitioned properly.

  For U-boot and MLO

  If files are located in Tarball write complete path including the file name.
      e.x. $:  /home/user/MyCustomTars/boot.tar.xz

  If files are located in a directory write the directory path
      e.x. $: /ti-sdk/board-support/prebuilt-images/

  NOTE: Not all platforms will have an MLO file and this file can
        be ignored for platforms that do not support an MLO.

  Update: The proper location for the kernel image and device tree
          files have moved from the boot partition to the root filesystem.
