AM437x EVM板子 串口通信无数据

请问使用的linux sdk版本是什么？
另外先参考以下帖子检查一下uboot和kernel中关于uart配置部分的内容。

感谢你的回复。

我看了下那个帖子，他是教如何修改console串口从默认的ttyO0 改为ttyO5, 我的console串口输出都是没有问题的，就是无法使用非console串口（如ttyO3）进行通信。但是把ttyO3配置为 console=ttyO3,115200n8 ，使用同样的测试程序又可以正常通信。


串口的uboot下配置：Kernel command line: console=ttyO0,115200n8 root=/dev/nfs nfsroot=192.168.1.5:/home/wp/work/project/linuxsrc/nfsroot,nolock rw ip=192.168.1.3:192.168.1.8:192.168.1.1:255.255.255.0::eth0:off





启动配置如下：
