U-Boot for Wandboard
|
||||
--------------------
|
||||
|
||||
This file contains information for the port of U-Boot to the Wandboard.
|
||||
|
||||
Wandboard is a development board that has two variants: one version based
|
||||
on mx6 dual lite and another one based on mx6 solo.
|
||||
|
||||
For more details about Wandboard, please refer to:
|
||||
http://www.wandboard.org/
|
||||
|
||||
Building U-boot for Wandboard
|
||||
-----------------------------
|
||||
|
||||
To build U-Boot for the Wandboard Dual Lite version:
|
||||
|
||||
$ make wanboard_dl_config
|
||||
$ make
|
||||
|
||||
To build U-Boot for the Wandboard Solo version:
|
||||
|
||||
$ make wanboard_solo_config
|
||||
$ make
|
||||
|
||||
Flashing U-boot into the SD card
|
||||
--------------------------------
|
||||
|
||||
- After the 'make' command completes, the generated 'u-boot.imx' binary must be
|
||||
flashed into the SD card;
|
||||
|
||||
$ sudo dd if=u-boot.imx of=/dev/mmcblk0 bs=512 seek=2; sync
|
||||
|
||||
(Note - the SD card node may vary, so adjust this as needed).
|
||||
|
||||
- Insert the SD card into the slot located in the bottom of the board (same side
|
||||
as the mx6 processor)
|
||||
|
||||
- Connect the serial cable to the host PC
|
||||
|
||||
- Power up the board and U-boot messages will appear in the serial console.
