TI中文支持网我刚刚买了TI DM6168 EVM评估板。拿到开发板后，按照DM816x/C6A816x/AM389x Evaluation Module Quick Start Guide ，上电启动，视频输出错误，我的启动开关SW3，SW4配置如下图，
但是没有视频输出，查了下串口打印输出

附件里是完整的串口打印信息
请教下各位专家，是什么原因导致的么？
alvin lu：
我建议你把SD卡格式化，然后重新编译一下，把MLO，uboot.bin和kernel放在SD卡的第一分区。在linux下进行操作。
还有文件系统，用TIezsdk包里的filesystem下面的argao什么的。解压，放在sd卡的rootfs。我有一系列关于DM8168的文章，你可以参考下。wenku.baidu.com/…/6de8c91e6bd97f192279e9e2.html

回复 alvin lu:
按照alvin lu 的文章，制作一张SD卡，但是当我设置为SD卡启动时，串口没有任何输出信息，不知道为什么啊？急救！！
