RTOS/66AK2H14: Invalid magic number in Single image header

Part Number: 66AK2H14

Tool/software: TI-RTOS

Hi,

We have designed  customized  board  using 66AK2H14. We are using CCSV7 and TI XDS 110 debug probe to connect board to CCS.

We are able to Flash MLO and gpio_led application using spi_flashwriter.

But when boot mode is changed to SPI,  facing below issue:

 
     **** PDK SBL ******
   SBL Revision: 01.00.07.00 (May 18 2018 - 13:05:07)
   Begin parsing user application
   MAGIC NUM: 202084688
   Invalid magic number in Single image header
   Jumping to user application...
 
Flashed same app to EVM , It was running successfully when boot mode is changed to SPI.
Only difference between EVM and custom board binary is MLO. For EVM we used sdk’s prebuilt MLO.
Q1. We just changed DDR3 configuration and Rebuilt MLO through makefile.Is there any other thing we are missing?
Regards,
Mahima Shanbag.
