Currently we need to build one U-boot image for each of the wandboard variants: quad, dual-lite and solo. By switching to SPL we can support all these variants with a single binary, which is very convenient. Based on the work from Richard Hu. Tested kernel booting on the three boards.

U-Boot for Wandboard
|
|
--------------------
|
|
|
|
This file contains information for the port of U-Boot to the Wandboard.
|
|
|
|
Wandboard is a development board that has three variants based on the following
|
|
SoCs: mx6 quad, mx6 dual lite and mx6 solo.
|
|
|

Building U-boot for Wandboard
|
|
-----------------------------
|
|
|
|
To build U-Boot for the Wandboard:
|
|
|
|
$ make wandboard_config
|
|
$ make
|
|
|
|
Flashing U-boot into the SD card
|
|
--------------------------------
|
|
|
|
- After the 'make' command completes, the generated 'SPL' binary must be
|
|
flashed into the SD card;
|
|
|
|
$ sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
|
|
|
|
(Note - the SD card node may vary, so adjust this as needed).
|
|
|
|
- Flash the u-boot.img image into the SD card:
|
|
|
|
sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync
|
|
|
|
- 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.
