I've flashed my u-boot.bin ,uImage,and rd-jffs2.bin into nand flash,

but there were some problems with the booting process,

could anyone help me out of these?

my console lags are as below:

    JFFS2 is obsolate and UBIFS is recommended for new design. UBIFS can be thought of as a JFFS2 successor with significant improvements in scalability and NAND support. If you still need JFFS2, you should switch back to Hamming HW ECC (not BCH8). See the below wiki for more details:

    Hi Pavel:

    Thanks for your reminding !

    First ,I went on trying to boot JFFS2 filesystem,so I switched back to Hamming HW ECC to flash u-boot.bin ,uImage,and rd-jffs2.bin into nand !

    but it couldn't get run at the very start!

    so, I took the following command:

    TI8168_EVM# mw.b 0x81000000 0xFF 0x260000
TI8168_EVM# tftp 0x81000000 u-boot.noxip.bin
TI8168_EVM# nand erase 0x0 0x260000     <=== Erasing the whole partition before flashing the image
TI8168_EVM# nandecc hw 2
TI8168_EVM# nand write.i 0x81000000 0x0 0x260000
TI8168_EVM# nandecc hw 0

    from http://processors.wiki.ti.com/index.php/DM816x_AM389x_PSP_U-Boot

    well,it could get started,but can't read uImage correctly ,because I've choosed  "nandecc hw 0" to flash uImage.

    then,could you guide me on how to make Hamming HW ECC be default in my evm-board ?

    --------------------------------------------------------------------------------------------------------------------------

    On the other way,I tried to boot with UBIFS filesystem,but there occured some probles in the process,

    my full console lags are below:

    This wiki is old, please use the below which is most up to date:

    The steps are:

    1. Switch to HW ECC hamming - TI8168_EVM#nandecc hw 0

    2. Flash u-boot to NAND

    3. Flash linux kernel to NAND

    4. Create JFFS2 filesystem

    5. Flash JFFS2 filesystem

    On the other way,I tried to boot with UBIFS filesystem,but there occured some probles in the process

    Make sure you have enabled the UBIFS in linux kernel:

    For UBIFS, try also with applying all the UBI/UBIFS/NAND related linux kernel patches from:

    arago-project.org/.../projects;a=shortlog;h=refs/heads/ti81xx-master

    See also the below e2e thread (which is for DM814x, but should be similar to DM816x):

    Hi Pavel :
    I've did switch back to Hamming HW ECC by command "nandecc hw 0 ",to flash u-boot.bin ,uImage,and rd-jffs2.bin into nand ,
    but it couldn't get run at the very start! No messages showed ! Best regards!

    Hi Pavel :

    In order to enable UBI/UBIFS support in u-boot, (processors.wiki.ti.com/.../UBIFS_Support)

    I've added the following macros :

    #define CONFIG_CMD_NAND

    #define CONFIG_CMD_UBI

    #define CONFIG_CMD_UBIFS

    #define CONFIG_RBTREE

    #define CONFIG_MTD_DEVICE

    #define CONFIG_MTD_PARTITIONS

    #define CONFIG_CMD_MTDPARTS

    #define CONFIG_LZO

    into my config file " /usr/local/ezsdk/board-support/u-boot-2010.06-psp04.04.00.01/include/configs/ti8168_evm.h",

    however, after flashing this recreated "u-boot.noxip.bin" into nand ,it couldn't start at the very first!

    No console messages showed!

    Could you please help me out of these?

    Thank you !

    Bset regards!

    Let us start from u-boot. Could you please provide me full console log of your sequence to flash the u-boot, I want to check your steps. Please flash your u-boot, and try with booting only the u-boot (do it step by step, put the kernel and fs aside for now).
