我的操作系统实在单操作系统ubuntu15.04的版本中发现的这个问题，在android内核的版本中没有出现uart0不能使用的问题，请问如何解决啊，各位大拿们!111

作者: mlt911213 时间: 2016-8-30 20:02
解决了吗？
我也不行

解决了吗？
我也不行

没有解决，但是使用了usb转串口的功能进行代替

作者: tangxuanlai 时间: 2016-12-7 23:05
不能使用的现象是什么？我的现在也不能用，串口只能接受到数据，不能发送出来

我现在无法收发啊！你们是怎么设置的

作者: sl410 时间: 2017-7-8 13:38

disabled蓝牙后，
&uart0 {
      status = "okay";
      dma-names = "!tx", "!rx";
      pinctrl-0 = <&uart0_xfer &uart0_cts>;
};
----》改为：
&uart0 {
      status = "okay";
};

&uart0 { 重复
第二个&uart0 { 要改成 &uart1 {

&uart0 {

不是重复的问题，应该是哪个地方有bug
