  2. Buildroot for Engicam i.CoreM6 RQS SOM platforms:
  3. *************************************************
  4. This file documents the Buildroot support for Engicam i.CoreM6 RQS
  5. SOM platform boards.
  6. i.CoreM6 Quad/Dual/DualLite/Solo RQS SOM Starter kits:
  7. https://www.engicam.com/vis-prod/101124
  8. This configuration uses U-Boot mainline and kernel mainline.
  9. Build
  10. =====
  11. First, configure Buildroot for the Engicam i.CoreM6 RQS:
  12. - for i.CoreM6 RQS Quad/Dual/DualLite/Solo:
  13. make engicam_imx6qdl_icore_rqs_defconfig
  14. Build all components:
  15. make
  16. You will find the following files in output/images/:
  17. - for i.CoreM6 Quad/Dual RQS:
  18. - imx6q-icore-rqs.dtb
  19. - for i.CoreM6 DualLite/Solo RQS:
  20. - imx6dl-icore-rqs.dtb
  21. - rootfs.ext4
  22. - rootfs.tar
  23. - sdcard.img
  24. - SPL
  25. - u-boot-dtb.img
  26. - uImage
  27. Create a bootable SD card
  28. =========================
  29. To determine the device associated to the SD card have a look in the
  30. /proc/partitions file:
  31. cat /proc/partitions
  32. Buildroot prepares a bootable "sdcard.img" image in the output/images/
  33. directory, ready to be dumped on a SD card. Launch the following
  34. command as root:
  35. dd if=output/images/sdcard.img of=/dev/<your-sd-device>
  36. sync
  37. *** WARNING! This will destroy all the card content. Use with care! ***
  38. For details about the medium image layout, see the definition in
  39. board/engicam/icorem6_rqs/genimage.cfg
  40. Boot the i.CoreM6 RQS boards with SD boot:
  41. =========================================
  42. To boot your newly created system:
  43. - insert the SD card in the SD slot of the board;
  44. - connect 3-wire RS232 serial port J7 on board, and connect with other
  45. serial end or USB cable(if serial-to-usb converter used) using
  46. a terminal emulator at 115200 bps, 8n1;
  47. - close JM2 for sd boot.
  48. - power on the board.
  49. Enjoy!
