  2. Buildroot for Engicam Is.IoT SOM platforms:
  3. ********************************************
  4. This file documents the Buildroot support for all Engicam Is.IoT MX6UL
  5. SOM platform boards.
  6. Is.IoT MX6UL SOM Starter kits:
  7. https://www.engicam.com/vis-prod/101122
  8. This configuration uses U-Boot mainline and kernel mainline.
  9. Build
  10. =====
  11. First, configure Buildroot for the Engicam Is.IoT MX6UL SOM:
  12. - for Is.IoT MX6UL SOM:
  13. make engicam_imx6ul_isiot_defconfig
  14. Build all components:
  15. make
  16. You will find the following files in output/images/:
  17. - imx6ul-isiot-emmc.dtb
  18. - rootfs.ext4
  19. - rootfs.tar
  20. - sdcard.img
  21. - SPL
  22. - u-boot-dtb.img
  23. - uImage
  24. Create a bootable SD card
  25. =========================
  26. To determine the device associated to the SD card have a look in the
  27. /proc/partitions file:
  28. cat /proc/partitions
  29. Buildroot prepares a bootable "sdcard.img" image in the output/images/
  30. directory, ready to be dumped on a SD card. Launch the following
  31. command as root:
  32. dd if=output/images/sdcard.img of=/dev/<your-sd-device>
  33. sync
  34. *** WARNING! This will destroy all the card content. Use with care! ***
  35. For details about the medium image layout, see the definition in
  36. board/engicam/isiot/genimage.cfg
  37. Boot the Is.IoT MX6UL boards with SD boot:
  38. =========================================
  39. To boot your newly created system:
  40. - insert the SD card in the SD slot of the board;
  41. - connect 3-wire RS232 serial port J28 on board, and connect with other
  42. serial end or USB cable(if serial-to-usb converter used) using
  43. a terminal emulator at 115200 bps, 8n1;
  44. - close JM3 for sd boot.
  45. - power on the board.
  46. Enjoy!
