27Environment Storage
28-------------------

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.

Fabio Estevam607dfdf2012-03-24 10:58:57 +000044Follow the instructions from doc/README.mx28_common to generate a bootable SD
45card.
46
47Insert the SD card in slot 0, power up the board and U-boot will boot.
