高手们好，
        自己打的板子，sd卡启动，最终卡在starting kenel，log如下：

uboot下环境参数为:
bootdelay=3
baudrate=115200
ipaddr=192.168.1.103
serverip=192.168.1.101
netmask=255.255.255.0

发现uboot有不一样的地方：
开发板是：CPU: Freescale i.MX6 family TO1.2at 792 MHz
自己的板子是：CPU: Freescale i.MX6 family TO1.5 at 792 MHz

这个好像是读寄存器得到的，这个有影响么？麻烦了！谢谢！
