What is the boot pins setting for SPI FLASH BOOT MODE and how to set it

As with the SPI Writer, i got the following error:

[C674X_0] Starting OMAP-L138 SPIWriter.
Will you be writing a UBL image? (Y or y)
n
Enter the application file name (enter 'none' to skip):
C:\SecureOut.bin

    We have used processor P/N : TMS320C6748BZWT in our board and write to SPI Flash is working.

    In the same board when we replaced the processor with P/N : TMS320C6748EZWT and tried write to the SPI Flash by connecting emulator with the SPI Writer, we are getting the following error:

    [C674X_0] Starting OMAP-L138 SPIWriter.
    Will you be writing a UBL image? (Y or y)
    n
    Enter the application file name (enter 'none' to skip):
    C:\SecureOut.bin
        INFO: File read complete.
        ERROR: Erasing SPI failed.
    SPI Flashing Failed!    SPI flashing failed!

    how can i fix this?

    The SPI flash Configuration is same and we have observed no activity on SPI lines  (cs, clk, simo, somi)

    Hello,

    Please check the instructions for spi flashing here. 

    Please also note that TI does not support bare-metal or TI-RTOS based SW development for C6748/OMAP-L138 anymore, as announced here. I would recommend you to check the consolidated resources provided in the announcement.

    Regards,
