      1 How to use U-Boot on Grinn's liteBoard
      2 --------------------------------------
      3 
      4 - Build U-Boot for liteBoard:
      5 
      6 $ make mrproper
      7 $ make liteboard_defconfig
      8 $ make
      9 
     10 This will generate the SPL image called SPL and the u-boot.img.
     11 
     12 - Flash the SPL image into the micro SD card:
     13 
     14 sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
     15 
     16 - Flash the u-boot.img image into the micro SD card:
     17 
     18 sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync
     19 
     20 - Jumper settings:
     21 
     22 S1: 0 1 0 1 1 1
     23 
     24 where 0 means bottom position and 1 means top position (from the
     25 switch label numbers reference).
     26 
     27 - Insert the micro SD card in the board.
     28 
     29 - Connect USB cable between liteBoard and the PC for the power and console.
     30 
     31 - U-Boot messages should come up.
