OMAPL138 boot with UBL "No magic number found"

Other Parts Discussed in Thread: OMAPL138, OMAP-L138

Hi,

I want to use ubl copy the U-Boot in OMAPL138.

I only change the DDR2 parameters in OMAP-L138_FlashAndBootUtils_2_40 and compile.

But when I download the sft_OMAPL138_SPI_MEM.bin into SPI Flash.

The UART print as follow:

OMAP-L138 initialization passed!
Booting TI User Boot Loader
        UBL Version: 1.65
        UBL Flashtype: SPI
Starting SPI Memory Copy...
No magic number found.
Looking for: 0x55424CBB, but read 0x41504954.
SPI Memory Boot failed.

I don't know much about the UBL and what is magic number ,someone help me?

    HI,

    What are your trying to do?

    Are your trying to boot linux on OMAPL138 board ?

    You can boot the board through AIS signed u-boot directly from SPI flash (no need UBL).

    Is this your TI EVM board or custom board ?

    Thanks for your advice！

    Yes,I want to use UBL and Uboot to boot Linux on OMAPL138 board.

    I am trying to use AISgen tools to generate AIS signed Uboot and I also have some questions.

    1、 Because I don't use UBL this time.Should I flash the AIS signed uboot into SPI_MEM address 0?And this means I must change the SPI-Writer(ccs project) about the adress?

    2、When generate AIS signed Uboot.It needs entrypoint address.Now I just use 0xC1080000.But I dont know the address exactly mean.Is it the execute address in RAM?

    I use custom board.

    Thanks!

    Hi Tong,

    1、 Because I don't use UBL this time.Should I flash the AIS signed uboot into SPI_MEM address 0?And this means I must change the SPI-Writer(ccs project) about the adress?

    It depends on your SPI writer versions (it may support UBL & u-boot )

    We have SFH tool for flashing u-boot images into SPI flash.

    2、When generate AIS signed Uboot.It needs entrypoint address.Now I just use 0xC1080000.But I dont know the address exactly mean.Is it the execute address in RAM?

    Yes.
