A40i-c V1.2核心板，SD卡烧写程序，系统起来之后，调试串口死掉了。

zhangwd

烧录新板子，linux ,A40i-c V1.2核心板，SD卡烧写程序,boot拨码开关off,SD可以升级，但是再重启，就出现卡死状态了，换过镜像、换过SD卡，现象依旧。。。
使用镜像：sun8iw11p1_linux_OKA40i_C_uart0-1024x600.img, md5sum校验之后是正确的。
下面是日志：

烧写之前测试调试串口有问题吗，有可能是串口线需要重新插拔，电脑usb口重插一下。
如果还不行就检查一下硬件通断，看看rx脚有没有断路

谢谢，应该是串口的问题，当前通过telnet登录进行操作的，谢谢
