0 `下面介绍在芯灵思A83T开发板上进行串口诊断的方法，首先需要准备USB TTL串口诊断线，笔者使用的PL2303芯片USB转串口线，首先插上USB转串口线在电脑上安装好驱动，然后连接USB TTL串口线的USB端到电脑，按Win+PauseBreak打开硬件管理器，查看安装好的驱动的COM号，打开终端管理器（笔者使用Putty），在终端管理器输入设备管理器里面的查看的COM号，在波特率位置填写115200，如下图所示接着将USB TTL串口线的RX TX GND线端分别连接芯灵思A83T开发板的DEBUG UART区域的TX RX GND，如下图然后给开发板上电并在终端管理器界面按打开，会看到如下终端诊断打印信息输入lsmod可以查看加载的模块驱动终端诊断信息如下 xxxxx~@@^ xxxxxx`x~\|~xxx^xxx^``xx\|x~p~`^x^^@~x▒ ▒▒▒\|▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒ ▒▒▒> ▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒ ▒▒▒▒▒▒▒▒▒>▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒ ▒▒▒▒▒▒▒▒▒▒▒▒ ▒▒▒▒▒~▒▒ ▒▒▒▒▒▒▒▒▒▒▒ ▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒ ▒▒▒▒▒▒▒▒▒▒▒▒▒<▒▒▒▒▒▒▒▒▒▒> ▒▒▒▒▒▒▒▒▒▒▒▒▒▒\|▒▒▒▒▒▒▒▒~▒▒▒▒▒`▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒~▒ ▒▒▒▒▒▒▒▒▒▒`▒▒▒▒▒▒▒▒▒▒`▒▒▒▒▒▒▒▒ ▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒ ▒▒▒~▒▒▒▒▒▒▒▒▒▒▒▒`▒▒▒▒▒▒▒▒▒▒▒ ▒▒▒▒`▒▒▒▒▒▒▒>▒▒`▒▒▒▒▒▒▒▒▒▒▒▒▒▒ ▒`▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒ >▒▒~▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒x▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒ ▒▒▒`▒▒ ▒▒▒▒▒▒▒▒▒▒`▒▒▒▒▒▒▒▒▒▒>▒▒▒`▒>`▒▒▒▒▒`▒▒▒▒▒▒▒▒▒▒▒▒`▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒>▒▒▒▒▒ HELL O!
