  2. Freescale i.MX6UL EVK board
  3. ***************************
  4. This file documents the Buildroot support for the Freescale i.MX6UL EVK board.
  5. Please read the i.MX6UL Evaluation Kit Quick Start Guide [1] for an
  6. introduction to the board.
  7. Build
  8. =====
  9. First, configure Buildroot for your i.MX6UL EVK board:
  10. make freescale_imx6ulevk_defconfig
  11. Build all components:
  12. make
  13. You will find in ./output/images/ the following files:
  14. - imx6ul-14x14-evk.dtb
  15. - rootfs.ext4
  16. - rootfs.tar
  17. - sdcard.img
  18. - u-boot.imx
  19. - zImage
  20. Create a bootable microSD card
  21. ==============================
  22. To determine the device associated to the microSD card have a look in the
  23. /proc/partitions file:
  24. cat /proc/partitions
  25. Buildroot prepares a bootable "sdcard.img" image in the output/images/
  26. directory, ready to be dumped on a microSD card. Launch the following
  27. command as root:
  28. dd if=./output/images/sdcard.img of=/dev/<your-microsd-device>
  29. *** WARNING! This will destroy all the card content. Use with care! ***
  30. For details about the medium image layout, see the definition in
  31. board/freescale/common/imx/genimage.cfg.template.
  32. Boot the i.MX6UL EVK board
  33. =========================
  34. To boot your newly created system (refer to the i.MX6UL EVK Quick Start Guide
  35. [1] for guidance):
  36. - insert the microSD card in the microSD slot of the board;
  37. - verify that your i.MX6UL EVK board jumpers and switches are set as mentioned
  38. in the i.MX6UL EVK Quick Start Guide [1];
  39. - put a micro USB cable into the Debug USB Port and connect using a terminal
  40. emulator at 115200 bps, 8n1;
  41. - power on the board.
  42. Enjoy!
