1FREESCALE MX28EVK 2================== 3 4Supported hardware: only MX28EVK rev D is supported in U-boot. 5 6Files of the MX28EVK port 7-------------------------- 8 9arch/arm/cpu/arm926ejs/mxs/ - The CPU support code for the Freescale i.MX28 10arch/arm/include/asm/arch-mxs/ - Header files for the Freescale i.MX28 11board/freescale/mx28evk/ - MX28EVK board specific files 12include/configs/mx28evk.h - MX28EVK configuration file 13 14Jumper configuration 15--------------------- 16 17To boot MX28EVK from an SD card, set the boot mode DIP switches as: 18 19 * Boot Mode Select: 1 0 0 1 (Boot from SD card Slot 0 - U42) 20 * JTAG PSWITCH RESET: To the right (reset disabled) 21 * Battery Source: Down 22 * Wall 5V: Up 23 * VDD 5V: To the left (off) 24 * Hold Button: Down (off) 25 26 27Environment Storage 28------------------- 29 30There are two targets for mx28evk: 31 32"make mx28evk_config" - store environment variables into MMC 33 34or 35 36"make mx28evk_nand_config" - store environment 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. 47
