imx开发板COM串口启动问题

串口问题

• 问题：

  1. imx6ull连接Mobaxterm串口调试，出现了连接上，但是不能输出和输入字符。
  2. imx6ull 通过USB连接电脑，显示有串口COM，但是在Mobaxterm中打开imx的串口时，在设备管理器中的端口COM就不见了，或者显示–不能识别/不能打开等等，并且系统接入的提示音会一直响。
  3. imx6ull的串口之前很长一段时间正常使用，突然就不能用了。

• 原因1：电脑USB缺少某些驱动，导致电脑串口的识别功能时好时坏。

• 原因2：开发板micro口硬件引脚发生某种问题

• 最终解决：更换micro硬件接口，串口调试功能稳定

• 未解决(以下都是提供问题排查的方法路径)
  解决路径：www.drivergenius.com
  重新单独烧写正确u-boot-dtb.imx文件,使串口能够正常运行。

  阅读：《嵌入式Linux应用开发完全手册V4.0_韦东山全系列视频文档-IMX6ULL开发板》【--第六章--6.4.3节---】
  -->如果电脑没有显示出端口号，就需要手动安装驱动，从驱动精灵官网（www.drivergenius.com）下载一个驱动精灵，安装、运行、检测，会自动安装上串口驱动。
  -->驱动精灵会自动检测电脑的整个驱动，安装补全缺少的驱动，就可以正常使用imx的终端界面了。
  
  

修改：通过以上方法，最后还是不能够解决串口问题，最终通过重新烧写u-boot-dtb.imx,解决了COM串口在Mobaxterm的输入输出问题。解决时间：2天 （时好时坏，还是未解决）

从中收获：了解了串口调试的整条线路，通过假设法从头测试，排除每一种情况，最终确定问题所在。

• 原因分析排查：从开发板电源供电到串口调试助手软件，中间经过：
  1. 12v2A电源供电
  2. uboot–Linux内核–文件系统
  3. UART控制器
  4. 开发板micro口
  5. 数据线
  6. 电脑USB口
  7. USB驱动（包括电脑本身的USB集成驱动和端口COM驱动）
  8. Mobaxterm软件

之前检查了电源供电、重新烧写了整个Linux系统、
更换了数据线、多台电脑测试串口
电脑的多个USB口测试、端口COM驱动的重装、USB集成驱动的重装
Mobaxterm连接Ubuntu测试软件是否出错

推断：（未能确定）
		1.可能是开发板的Linux系统出错
		2.或者win10系统缺少某些驱动软件
最终判定：开发板micro口硬件问题，需要更换micro接口
在烧写系统的时候将不匹配的u-boot烧入开发板中，导致串口不能正常运行，	但是板子的程序能够正常运行	

这里提醒一下：imx6ull连接WiFi的流程 记录
