DM6467烧写UBL到EEPROM



我的板子启动显示如下

Booting PSP Boot Loader

Starting NAND Copy

NAND Boot failed. Starting UART

BOOTPSP

也不知道怎么搞的,就这样了,然后我想基于CCS3.3烧写ubl、U-boot,但是一直不行。

就是在CCS3.3运行到提示输入文件名的时候,输入了文件名后(绝对地址也试了)ccs就显示

01  Testing spirom...

Starting SPIWriter.

Enter the File Name

davinciUBL.bin

File davinciUBL.bin Open failed

    FAIL... error code -1... quitting

***ALL Tests P<b>bottom</b>ed***

请专家给指教
