使用ampy上传下载程序

ampy -p /dev/ttyUSB0 ls
/boot.py
ampy支持的命令：

• get  从开发版下载文件ampy -p /dev/ttyUSB0 get boot.py
• ls  list所有开发板文件
• mkdir 在开发板创建文件夹
• reset 开发板软件重置
• rmdir 删除文件夹
• run 运行脚本并输出

运行一个示例

(base) ping@ping:~/.vscode/extensions/rt-thread.rt-thread-micropython-1.0.11/microExamples/examples/03.board/3.esp8266$ ampy -p /dev/ttyUSB0 put blink.py 
(base) ping@ping:~/.vscode/extensions/rt-thread.rt-thread-micropython-1.0.11/microExamples/examples/03.board/3.esp8266$ ampy -p /dev/ttyUSB0 run blink.py
 

因为RT-thread 插件无法找到串口，所以用ampy上传和运行了。
