选择在SD卡启动，

setenv bootargs 'console=ttyO0,115200n8 root=/dev/mmcblk0p2 mem=128M rootwait';setenv bootcmd 'mmc rescan 0; fatload mmc 0
0x81000000 uImage; bootm 0x81000000';boot
bootargs和bootcmd配置如上，根文件系统貌似能够挂载，但是提示无init程序

楼主问题解决了没？你貌似用的也是TI的产品，什么型号，我现在用的是IPNC(Ti8148）的，遇到同样问题。
楼主如果问题解决了，迫切希望发我一份。bang417@163.com
谢谢！！

mount 返回 -2 就是 no such file or directory 吧,

devtmpfs: error mounting -2

我猜测一下，你的根文件系统里面是不是忘掉了/dev目录啊
