  2. Freescale i.MX28 EVK board
  3. **************************
  4. This file documents the Buildroot support for the Freescale i.MX28 EVK board.
  5. Read the i.MX28 Evaluation Kit Quick Start Guide [1] for an introduction to the
  6. board.
  7. Build
  8. =====
  9. First, configure Buildroot for your i.MX28 EVK board:
  10. make freescale_imx28evk_defconfig
  11. Build all components:
  12. make
  13. You will find in ./output/images/ the following files:
  14. - imx28-evk.dtb
  15. - rootfs.tar
  16. - u-boot.sd
  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. Then, run the following command as root:
  24. *** WARNING! The command will destroy all the card content. Use with care! ***
  25. sudo dd if=output/images/sdcard.img of=/dev/<your-microsd-device>
  26. Boot the i.MX28 EVK board
  27. =========================
  28. To boot your newly created system (refer to the i.MX28 EVK Quick Start Guide
  29. [1] for guidance):
  30. - insert the SD card in the SD Card Socket 0 of the board;
  31. - verify that your i.MX28 EVK board jumpers and switches are set as mentioned
  32. in the i.MX28 EVK Quick Start Guide [1];
  33. - connect an RS232 UART cable to the Debug UART Port and connect using a
  34. terminal emulator at 115200 bps, 8n1;
  35. - power on the board.
  36. Enjoy!
