uboot+bsp_linux3.4+buildroot-这个构建内核的方案，如何让lcd与串口同时作为终端。有的网友说在uboot中改，有的说在inittab中加，都没有用。
请问到底如何改呀，晕哥不知道有解决这个问题的链接，真心求救。可能自己的LINUX底子太薄了，以前一直在搞STM32和FPGA和QT。现在我自己画的板可以通过串口敲命令运行QT4，例如./whycan_MENU -qws& 还有，通过USB接的鼠标键盘也可以在QT中使用。

就三个地方提到了ttyS0，我在前面加console=tty0 还是没有用，下面的是uboot编译脚本

[ $? -ne 0 ] && echo "build u-boot Failed"--------------------------------------------------------------------------------------------------------------------------

原来是官方的uboot(u-boot-2011.9)，看来确实很少人用这个.
