    Hi

             This is VAsu.I am using AM1808/OMAP-L138 CARRIER BOARD. on the base board we have only 4 switches to set boot mode of the board. I don't have enough data about that board. I tried to erase NAND flash on the board. it was successful. from that time I am not getting UBOOT prompt. I was trying to put UBL and Uboot in NAND flash. For that i am using UART boot host ver 1.3. I got pre build UBL images from OMAP-L138_FlashAndBootUtils_2_36 and I installed .net frame work in my pc. I am not getting BOOTME message on the serial port. It is giving the fallowing message on flash tool,

    File IO): Read 12564 bytes from file C:\Users\20036383\Desktop\OMAP-L138_FlashAndBootUtils_2_36\OMAP-L138\CCS\UBL_ARM\UBL_OMAPL138_NAND.ais.
    (Serial Port): Opening COM1 at 115200 baud...
    (AIS Parse): Read magic word 0x41504954.
    (AIS Parse): Waiting for BOOTME... (power on or reset target now)

    after resetting the board i am not getting any display in flash tool utility. can you please suggest me the way to get control on the board again.

    Thanks

      Hi,

      use sfh_OMAP-L138.exe tool whixh is present in the flashing tools, for flashing the u-boot and ubl.

      $ mono sfh_OMAP-l138.exe (gives options)

      Use appropriate options for flashing.

      Thx,
