關於 Wrong Image Format for bootm command

这个从nand上boot uImage了，是不是有跳线需要设置呢

吧printenv打印出来，看看是不是从nand启动的

虽然都叫MLO，uboot，但这是在makefile改名得来的，之前有nand，sd之分的，你的编译条件有问题。

我MLO 與 Uboot 都是從emmc啟動的, uboot可以正常啟動,但是無法載kernel

emmc boot分區

MLO,uboot.,uImage

emmc rootfs分區

FileSystem

下列為printenv

你跟一下，好像SD卡驱动还有些问题

mmc_send_cmd : timeout: No status update
Card did not respond to voltage select!

另外nand的驱动也没有加上去啊
