30There are two targets for mx28evk:
31
32"make mx28evk_config"		- store enviroment variables into MMC
33
34or
35
36"make mx28evk_nand_config"	- store enviroment variables into NAND flash
37
38Choose the target accordingly.
39
40Note: The mx28evk board does not come with a NAND flash populated from the
41factory. It comes with an empty slot (U23), which allows the insertion of a
4248-pin TSOP flash device.
43
44Follow the instructions from doc/README.mxs to generate a bootable SD card.
45
46Insert the SD card in slot 0, power up the board and U-boot will boot.
