首先我从nfs已经成功把内核下载到0x80800000,把设备树下载到了0x83000000然后使用bootz 80800000 - 83000000成功启动内核后显示挂载内核系统失败，为什么会导致这个问题？
日志信息太少，看不出原因；大概率是 emmc 的文件系统异常，导致无法挂载；
我正常启动是可以的。我是在uboot里执行的命令，下面是我的实际操作

在 u-boot 命令行先执行以下命令，然后再看能否起来；
setenv mmcargs setenv bootargs console=${console},${baudrate} root=/dev/mmcblk1p2 rootwait rw
看上去是 u-boot 给 kernel 传的参数没有文件系统分区导致的；
你可以对比一下正常的启动日志；
[ 0.000000] Kernel command line: noinitrd console=ttymxc0,115200
还是原来一样的现象
那你贴一个正常启动日志我看看，顺便把 u-boot 的环境变量给贴出来（启动异常的时候）；

以下是我的推测，如果不行，我也没有办法；
正常日志
- 在 uboot 中有打印：Booting from mmc …；表明 mmcboot 有执行，那么 run mmcargs 也会有执行；
- 在 kernel 日志中有打印：[ 0.000000] Kernel command line: console=ttymxc0,115200 root=/dev/mmcblk0p2 rootwait rw
异常日志
- 在 uboot 中没有打印：Booting from mmc …；表明 mmcboot 没有执行，那么 run mmcargs 也没有执行，那么 bootargs 为空；
综上
建议在 uboot 命令行处执行 bootargs 的环境变量配置；
setenv bootargs console=${console},${baudrate} root=/dev/mmcblk0p2 rootwait rw
