  1. U-Boot for Wandboard
  2. --------------------
  3. This file contains information for the port of U-Boot to the Wandboard.
  4. Wandboard is a development board that has three variants based on the following
  5. SoCs: mx6 quad, mx6 quad plus, mx6 dual lite and mx6 solo.
  6. For more details about Wandboard, please refer to:

  8. Building U-Boot for Wandboard
  9. -----------------------------
  10. To build U-Boot for the Wandboard:
  11. $ make wandboard_config
  12. $ make
  13. Flashing U-Boot into the SD card
  14. --------------------------------
  15. - After the 'make' command completes, the generated 'SPL' binary must be
  16. flashed into the SD card;
  17. $ sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
  18. (Note - the SD card node may vary, so adjust this as needed).
  19. - Flash the u-boot.img image into the SD card:
  20. sudo dd if=u-boot-dtb.img of=/dev/mmcblk0 bs=1k seek=69; sync
  21. - Insert the SD card into the slot located in the bottom of the board (same side
  22. as the mx6 processor)
  23. - Connect the serial cable to the host PC
  24. - Power up the board and U-Boot messages will appear in the serial console.
