看错误提示找不到设备树。没有拷贝设备树？
you will need to copy the MLO and u-boot.img files to the boot partition. At this point, the card is now bootable in the SD card slot. We default to using /boot/zImage on the rootfs partition and the device tree file loaded from /boot with the same name as in the kernel.
请问是从SD卡启动吗?
Shine：
BBB的设备树是am335x-boneblack.dtb。请看一下uboot环境变量里的fdtfile是怎么设置？
Nancy Wang：
printenv打印信息也贴出来看一下。

通过修改fdtfile 后可以正确读取am335x-boneblack.dtb和uimage了，但好像还是没有从SD卡上引导内核，应该是启动参数有问题，不知道在哪里修改这个参数，是在configs/am335x_evm.h 这个文件里修改嘛

请问您用的是BBB板子吗？有没有按S2键从SD卡启动？可以先用Prebuild里的文件看整个启动流程有没有问题。另外，请参考下面的帖子看是否有帮助。
