dm365 uboot



我用的是dm365,我已将u-boot-1.3.4-dm365_evm.bin烧写至0x320800处了,可是启动的时候为什么还找不到:TI UBL Version: 1.50

Booting Catalog Boot Loader

BootMode = NAND

Starting NAND Copy...

Valid magicnum, 0xA1ACED66, found in block 0x00000019.

No valid boot image found!

NAND Boot failed.

Aborting...

  • 请将问题描述得清楚一些,有用的信息太少了,看不出问题所在。

    你的uboot烧写是怎么烧写进NAND FLASH的?

    从你的启动打印出的信息看到,你的UBL启动正常,并且它找到了你的uboot的幻数,就是说,它找到了你的uboot的描述符了,得到了要启动你的uboot的一些相关信息,正常来说,就会启动uboot,接着会出现uboot的打印信息了。

    但你这个却找不到uboot image,我猜想,你可能是烧写不对,或是少烧写了uboot的描述符,或是描述符与你实际的uboot地址对不上。

  • The U-boot header was needed buy UBL.

    You should program the U-boot header in NAND address 0x320000, NAND Block 0x19, Page 0.

    The Header contents maybe:

    a1aced66 81080000 0000004a 00000019 00000001 81080000
