Hi All.

I am wondering how to create a file on MLO uboot DVRRDK-3.5.0.5.

How to SD boot without using the MLO file?

Thanks.

    Hi,

    The MLO file file and u-boot_DM810X_UD_DVR.sd.bin for SD boot will be generated in your tftphome directory once you build the uboot for DM8107 UD DVR. 

    Format the SD Card to HP disk format utitility V2.6 to FAT32 and copy the following files to SD Card

    1) MLO

    2) u-boot_DM810X_UD_DVR.sd.bin

    3) u-boot_DM810X_UD_DVR.bin

    4) u-boot_DM810X_UD_DVR.min.nand 

    Put the SW1[10:1] in the following configuration  0001010111 -> This is indicated in SD boot mode configuration near to Battery.

    Insert the SD card and power on the board. Stop the prompt at uboot stage 2 and flash the uboot.min and uboot to NAND using the following commands

    -Boot Min
    =========================================
    mw.b 0x81000000 0xFF 0x20000;
    mmc rescan 0;
    fatload mmc 0 0x81000000 u-boot_DM810X_UD_DVR.min.nand;
    nand erase 0x0 0x20000;
    nand write 0x81000000 0x0 0x20000;

    U-Boot
    ==========================================
    mw.b 0x81000000 0xFF 0x200000;
    mmc rescan 0;
    fatload mmc 0 0x81000000 u-boot_DM810X_UD_DVR.bin;
    nand erase 0x20000 0x220000;
    nand write 0x81000000 0x20000 0x220000;

    ===================================================================================
    ===================================================================================

    Power recycle the board and start with NAND mode(SW1[10:1] - 0001010010

    Hope this answers your Query

    Regards,

    hi Arun.


    MLO and u-boot_DM810X_UD_DVR.sd.bin  will not be created from DVRRDK-3.5.0.5

    so. build stage1 and stage2 image to add the contents of build_uboot.mk.

    MLO file generated file any of those?

    Thanks.
