    Hi Naresh,

    Basically booting from SD card is needed to take the board to fastboot mode in order to flash the eMMC storage.Thats because there's no u-boot in the eMMC (first time boot).. So you have to copy u-boot.bin and MLO files to an SD card (boot partition) and then boot the target board from this external SD card. You should change the SYSBOOT switch settings to boot from external SD card: 01011101.

    As its mentioned in the Release that you provided, it's noted that "SD Card Boot is not supported in this release." (see "Flashing OMAP4 Hardware" chapter ).

    But I suppose that you are able to re-flash the eMMC using fastboot..

    Naresh k said:
    After flashing the MLO , x-loader ,etc using fastboot and changed the SW settings and reboot the tablet.

    In that case there should be an issues with the build itself, not with the SD Card boot procedure.. I'll try this release myself and reply back.

    Hi Naresh,

    The issue is not reproducible with the L27.IS.2.M1 OMAP4 Release.. Make sure you're completing the steps correctly and the AFS has build clean..

    Apart of this I found similar problem with PandaBoard.. Here's the solution:

    I have just found a brutal workaround: Simply, I remove the bluetooth.ko LKM
    from the /system/modules location.
    Essentially one needs to issue the following commands:
    # mount -o remount,rw /system
    # rm /system/modules/bluetooth.ko

    It may be difficult to type the above commands on the console prompt,
    as the frequently repeated "ldisc..." errors make it problematic.
    If you want to do it without being disturbed but the messages, try to
    activate the ADB shell, with simpler for typing commands
    # netcfg eth0 up
    # netcfg eth0 dhcp
    # ifconfig eth0
    Then set the ADBHOST on X86 system to the IP address shown by the above "ifconfig" and
    use "adb shell" to get more quiet environment for tinkering with the bluetooth.ko.
