Create a README.mxs file that contains instructions on how to use U-boot for both MX23 and MX28. As boot from NAND has only been tested on mx28, make it clear that it only applies to MX28. While at it, do some small cleanups for the sake of consistency: - Use "MX28" instead of "i.MX28" - Use "section" instead of "chapter" when referring to specific parts of the reference manual chapters.

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 enviroment variables into MMC
|
|
|
|
or
|
|
|
|
"make mx28evk_nand_config" - store enviroment 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.
