board/liteboard: Add support for liteBoard
liteBoard is a development board which uses liteSOM as its base. Hardware specification: * liteSOM (i.MX6UL, DRAM, eMMC) * Ethernet PHY (id 0) * USB host (usb_otg1) * MicroSD slot (uSDHC1) Signed-off-by: Marcin Niestroj <m.niestroj@grinn-global.com>

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.
