omapl138在用ubl从spiflash 搬运 uboot到内存mddr中时,会漏掉开头的一些信息,

Other Parts Discussed in Thread: OMAP-L138, AM1808

请问,刚接触omapL138几个月,对底层不是很熟,一块是开发板,一块时自己做的板子;

对比,自己做的板子ubl从spiflash   搬运 uboot到内存mddr中时,会漏掉开头的一些uboot的相关信息,如uboot的起始地址等,但rbl是能从flash搬运ubl的,这时怎回事啊,有没有可能在烧写时的握手出了问题?

对spiwriter.out有些疑问,这个烧写程序是怎样实现和spiflash握手烧写的?
