  2. Freescale i.MX6ULL EVK board
  3. ****************************
  4. This file documents the Buildroot support for the Freescale i.MX6ULL EVK board.
  5. Build
  6. =====
  7. First, configure Buildroot for your i.MX6ULL EVK board:
  8. In order to to do so there are two supported options:
  9. make freescale_imx6ullevk_defconfig
  10. if you plan to use NXP provided U-Boot and kernel.
  11. or
  12. make imx6ullevk_defconfig
  13. if you plan to use mainline U-Boot and mainline kernel.
  14. Build all components:
  15. make
  16. You will find in output/images/ the following files:
  17. - boot.vfat
  18. - imx6ull-14x14-evk.dtb
  19. - rootfs.ext2
  20. - rootfs.ext4
  21. - rootfs.tar
  22. - sdcard.img
  23. - u-boot.bin
  24. - u-boot.imx
  25. - zImage
  26. Create a bootable SD card
  27. =========================
  28. To determine the device associated to the SD card have a look in the
  29. /proc/partitions file:
  30. cat /proc/partitions
  31. Buildroot prepares a bootable "sdcard.img" image in the output/images/
  32. directory, ready to be dumped on a SD card. Launch the following
  33. command as root:
  34. dd if=./output/images/sdcard.img of=/dev/<your-sd-device>
  35. *** WARNING! This will destroy all the card content. Use with care! ***
  36. For details about the medium image layout, see the definition in
  37. board/freescale/common/imx/genimage.cfg.template.
  38. Boot the i.MX6ULL EVK board
  39. ===========================
  40. To boot your newly created system (refer to the i.MX 6ULL EVK Quick Start Guide [1] for guidance):
  41. - insert the SD card in the micro SD slot of the board;
  42. - put a micro USB cable into the Debug USB Port and connect using a terminal
  43. emulator at 115200 bps, 8n1;
  44. - power on the board.
  45. Enjoy!
