| 34 | or |
| 35 | |
| Robert P. J. Day | 1bce2ae | 2013-09-16 07:15:45 -0400 | [diff] [blame] | 36 | "make mx28evk_nand_config" - store environment variables into NAND flash |
| Fabio Estevam | ab461be | 2013-03-07 11:28:19 +0000 | [diff] [blame] | 37 | |
| 38 | Choose the target accordingly. |
| 39 | |
| 40 | Note: The mx28evk board does not come with a NAND flash populated from the |
| 41 | factory. It comes with an empty slot (U23), which allows the insertion of a |
| 42 | 48-pin TSOP flash device. |
