关于4412上移植linux3.4的问题

[cbyiwork]

各位朋友，我在尝试将linux3.4移植到itop4412开发板上时，碰到如下问题
1、系统没有控制台打印信息
2、可以使用early_print，经过跟踪，我发现程序进入到start_kernel，并且进入到rest_init
3、uboot传递给内核的参数正确，我用early_printk打印cmd_line，有console=ttySAC2,115200和厂家移植
4、直接在printk->vprintk中键入early_printk(fmt,args);，能看到类似linux启动的打印
那么，请大侠指教
是我的程序控制台没启动起来吗？还是menuconfig中没有开启打印，但凡有点可疑的地方都打开试过了，但是，就是不行
感谢大家的解答

附上我在printk中用early_printk的打印信息
