I operate according to the document  <<TI816X-PSP-04.00.00.10-U-Boot.pdf>>,but  failed to boot the evm board by nand flash.

Who can tell me the right steps to run NAND flash boot?

    Xiao,

    Can you describe the failure and your setup here?  Are you using a DDR2 EVM or DDR3 EVM? If you are using EZSDK, are you using the prebuilt image or are you building your own uboot ? Are your switch settings set to the NAND bootmode? Did the uboot image u-boot.noxip.bin get flashed correctly as described in TI816X-PSP-04.00.00.10_Flashing_tools_guide.pdf ? YOu should see the following message after you flash the uboot

    Application is successfully flashed
    NAND boot preparation was successful!

    If yes, are your serial port setting configured to what is mentioned in the document?

    Regards,

    Rahul

    I use the prebuild image in ezsdk_5_01_01_80 and a DDR3 EVM.

    1)Flashing U-Boot from U-Boot

    TI8168_EVM# mw.b 0x81000000 0xFF 0x260000

    TI8168_EVM# tftp 0x81000000 u-boot.noxip.bin

    TI8168_EVM# nand erase 0x0 0x260000    

    TI8168_EVM# nandecc hw 2

    TI8168_EVM# nand write.i 0x81000000 0x0 0x260000

    TI8168_EVM# nandecc hw 0

    then power off.

    2)changge SW3、SW4、SW1(daughter card).

    3)power on

    but the debug serial com dose not print anything.

    is there some errors in my operations?
