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 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.
