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