  1. FREESCALE MX28EVK
  2. ==================
  3. Supported hardware: only MX28EVK rev D is supported in U-boot.
  4. Files of the MX28EVK port
  5. --------------------------
  6. arch/arm/cpu/arm926ejs/mxs/ - The CPU support code for the Freescale i.MX28
  7. arch/arm/include/asm/arch-mxs/ - Header files for the Freescale i.MX28
  8. board/freescale/mx28evk/ - MX28EVK board specific files
  9. include/configs/mx28evk.h - MX28EVK configuration file
  10. Jumper configuration
  11. ---------------------
  12. To boot MX28EVK from an SD card, set the boot mode DIP switches as:
  13. * Boot Mode Select: 1 0 0 1 (Boot from SD card Slot 0 - U42)
  14. * JTAG PSWITCH RESET: To the right (reset disabled)
  15. * Battery Source: Down
  16. * Wall 5V: Up
  17. * VDD 5V: To the left (off)
  18. * Hold Button: Down (off)
  19. Environment Storage
  20. -------------------
  21. There are two targets for mx28evk:
  22. "make mx28evk_config" - store environment variables into MMC
  23. or
  24. "make mx28evk_nand_config" - store environment variables into NAND flash
  25. Choose the target accordingly.
  26. Note: The mx28evk board does not come with a NAND flash populated from the
  27. factory. It comes with an empty slot (U23), which allows the insertion of a
  28. 48-pin TSOP flash device.
  29. Follow the instructions from doc/README.mxs to generate a bootable SD card.
  30. Insert the SD card in slot 0, power up the board and U-boot will boot.
