we  test dm368  use  spi flash bootmode   . when use ti tool sfh_DM36x.exe  copy the ubl binary file  to spi flash success,

 but rbl not load ubl .the  ubl binary in spi flash is no problem  .

we  look at DM368 BOOT DATASHEET about spi boot mode

the spi boot header is

SpiBootInfo.magicNum = 0xA1ACED00 ;

SpiBootInfo.entryPoint = 0x100;

SpiBootInfo.appSize = 0x2104;

SpiBootInfo.dummy = 0x0000;

SpiBootInfo.memAddress = 0x1000;(ubl stor in spi flash)

SpiBootInfo.ldAddress = 0x00000020;

 . dm368 rbl not support spi flash ?   spi flash is MX25L6406E
