用教程方法打开rk3288的uart3失败，跪求解答
1.按照教程将sdk包中的是dts中加入下面的代码：&uart_gps {
status = "okay";
dma-names = "!tx", "!rx";
pinctrl-0 = <&uart3_xfer &uart3_cts>;
};
2.返回kernel目录执行 make命令
3.将生成的kernel resource写入板子中，启动设备
4.将做好的串口转usb线连接两个设备，出现问题：
@如果接入调试串口，串口转usb电路板上提示灯正常闪烁
@接入打开的uart3串口，串口转usb提示灯一直显示，没有闪烁？？这是为什么啊
@用ls 查看dev/ttys*，结果显示没有ttys3,但我用echo向设备输入后，再用ls显示设备，此时能正常显示
@如何操作，设备一打开时就能用ls显示出ttys3设备
我也遇到这个问题，请楼主指导下

用哪个SDK？ gowhere 发表于 2015-12-8 14:46
/dts-v1/;
#include "rk3288.dtsi"
用这种方法打开出现的问题跟2楼相同，并且万能表测电压，为0 我的dts文件 zhansb 发表于 2015-12-8 14:48
用哪个SDK？
原来的板子是双系统的。我在你们网站上下载了一个android4。4的，刷入开发板，同时下载的sdk是你们网站上的4。4版本sdk。
我先整个编译，然后安装教程更改dts，编译，刷入开发板 在默认版最新更新下根据wiki步骤试过有ttyS3设备，收发也没问题：

我没有更新，就是用的下载的sdk源码整个编译，然后部分编译，这个有影响吗 gowhere 发表于 2015-12-8 15:49

更新后，修改uart3后完整烧录试试
