- How to use U-Boot on Grinn's liteBoard
- --------------------------------------
- - Build U-Boot for liteBoard:
- $ make mrproper
- $ make liteboard_defconfig
- $ make
- This will generate the SPL image called SPL and the u-boot.img.
- - Flash the SPL image into the micro SD card:
- sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
- - Flash the u-boot.img image into the micro SD card:
- sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync
- - Jumper settings:
- S1: 0 1 0 1 1 1
- where 0 means bottom position and 1 means top position (from the
- switch label numbers reference).
- - Insert the micro SD card in the board.
- - Connect USB cable between liteBoard and the PC for the power and console.
- - U-Boot messages should come up.
