  2. Freescale i.MX8MN EVK board
  3. ***************************
  4. This file documents the Buildroot support for the i.MX8M Nano EVK board.
  5. Build
  6. =====
  7. First, configure Buildroot for the i.MX8MN EVK board:
  8. make freescale_imx8mnevk_defconfig
  9. Build all components:
  10. make
  11. You will find in output/images/ the following files:
  12. - bl31.bin
  13. - boot.vfat
  14. - ddr4_201810_fw.bin
  15. - ddr_fw.bin
  16. - fsl-imx8mn-ddr4-evk.dtb
  17. - Image
  18. - imx8-boot-sd.bin
  19. - rootfs.ext2
  20. - rootfs.ext4
  21. - rootfs.tar
  22. - sdcard.img
  23. - u-boot.bin
  24. - u-boot.imx
  25. - u-boot.itb
  26. - u-boot-nodtb.bin
  27. - u-boot-spl.bin
  28. - u-boot-spl-ddr.bin
  29. Create a bootable SD card
  30. =========================
  31. To determine the device associated to the SD card have a look in the
  32. /proc/partitions file:
  33. cat /proc/partitions
  34. Buildroot prepares a bootable "sdcard.img" image in the output/images/
  35. directory, ready to be dumped on a SD card. Launch the following
  36. command as root:
  37. dd if=output/images/sdcard.img of=/dev/<your-sd-device>
  38. *** WARNING! This will destroy all the card content. Use with care! ***
  39. For details about the medium image layout, see the definition in
  40. board/freescale/common/imx/genimage.cfg.template_imx8.
  41. Boot the i.MX8MN EVK board
  42. ==========================
  43. To boot your newly created system (refer to the i.MX8MNano EVK Quick Start Guide
  44. [1] for guidance):
  45. - insert the SD card in the SD slot of the board;
  46. - Configure the switches as follows (X = "don't care"):
  47. SW1101: 1100XXXXXX [D1-D10]
  48. SW1102: XXXXXXXXXX [D1-D10]
  49. - put a micro USB cable into the Debug USB Port and connect using a terminal
  50. emulator at 115200 bps, 8n1;
  51. - power on the board.
  52. Enjoy!
