| 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) |

| 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. |
