  2. Freescale i.MX7D SDB board
  3. ***************************
  4. This file documents the Buildroot support for the Freescale i.MX7D SDB board.
  5. Build
  6. =====
  7. First, configure Buildroot for your i.MX7D SDB board:
  8. make freescale_imx7dsabresd_defconfig
  9. Build all components:
  10. make
  11. You will find in output/images/ the following files:
  12. - imx7d-sdb.dtb
  13. - rootfs.ext4
  14. - rootfs.tar
  15. - sdcard.img
  16. - u-boot.imx
  17. - zImage
  18. Create a bootable SD card
  19. =========================
  20. To determine the device associated to the SD card have a look in the
  21. /proc/partitions file:
  22. cat /proc/partitions
  23. Buildroot prepares a bootable "sdcard.img" image in the output/images/
  24. directory, ready to be dumped on a SD card. Launch the following
  25. command as root:
  26. dd if=./output/images/sdcard.img of=/dev/<your-sd-device>
  27. *** WARNING! This will destroy all the card content. Use with care! ***
  28. For details about the medium image layout, see the definition in
  29. board/freescale/common/imx/genimage.cfg.template.
  30. Boot the i.MX7D SDB board
  31. =========================
  32. To boot your newly created system:
  33. - insert the SD card in the SD slot of the board;
  34. - put a micro USB cable into the Debug USB Port and connect using a terminal
  35. emulator at 115200 bps, 8n1;
  36. - power on the board.
  37. Enjoy!
