DM36x Boot Issue

Hi All,

I am using TMS320DM365ZCED30  with NAND :MT29F2G08ABAEAH4-IT:E (2Gb density,x8 width) in my board.

We flashed the code from SD card to the NAND It is flashing in to NAND successlfully But When I am trying to boot from NAND It printing below print continuosly:

"DM36x initialization passed!
TI UBL Base Version: 1.50
Boot Loader BootMode = NAND
Starting NAND Copy..."

Then I tried same code in different board it working fine.Can any body tell me how to resolve this............

    Can you format the NAND completely once before you flash your software on it? You can do it from either uboot or Kernel.

    Yes I did NAND erase and NAND scrub from U-boot (booted from SD card),When i boot from NAND same prints are coming continuously .

    The prints are as shown below:

    "

    DM36x initialization passed!
    TI UBL Base Version: 1.50
    Boot Loader BootMode = NAND
    Starting NAND Copy...

    DM36x initialization passed!

     Thank you......

    Hi all,

    we are also working on DM365 and we are using our customized board.we are also getting same problem like whenever i boot from NAND we are getting continuous prints but when we boot from SD card no issue board is booting well.


    The prints are as shown below:

    DM36x initialization passed!
    TI UBL Base Version: 1.50
    Boot Loader BootMode = NAND
    Starting NAND Copy...

    DM36x initialization passed!
    TI UBL Base Version: 1.50
    Boot Loader BootMode = NAND
    Starting NAND Copy...

    DM36x initialization passed!
    TI UBL Base Version: 1.50
    Boot Loader BootMode = NAND
    Starting NAND Copy...

    DM36x initialization passed!
    TI UBL Base Version: 1.50
    Boot Loader BootMode = NAND
    Starting NAND Copy...

    DM36x initialization passed!
    TI UBL Base Version: 1.50
    Boot Loader BootMode = NAND
    Starting NAND Copy...

     

    Thank you ,
