      请问各位大佬MQ Quad的Uart5应该怎么启动呢?
      目前用的https://github.com/open-cores/mangguo-h616-armbian.git这个代码
      修改了sun50i-h616-mangopi-mcore.dts,添加了uart5节点。
      修改了sun50i-h616.dtsi,添加了uart5的PH2、PH3引脚。目前dmesg可以看到UART5启动,但是用minicom打开/dev下对应的设备无法发送接收,直接把串口的tx rx短接也看不到回显。

          @whycanservice 您好,目前在uboot里已经关闭这个mux,设备树里还需要修改啥吗?
