4. 安装PYOCD

当将python安装之后，按下键盘的 win+r 键，在屏幕左下角会弹出一个小窗口，在其输入框中输入 cmd 之后按下回车键：

按照上图点击运行python会得到如下图所示的窗口：

DShanMCU-RA6M5-DAP-007

点击选中该窗口，输入/复制粘贴 python -m pip install -U pyocd 然后按回车，之后耐心等待安装完成，如下图所示：

DShanMCU-RA6M5-DAP-008

如果提示报错，一般都是因为网络问题导致的，因为相关资源需要在国外拉取，所以，这需要多次尝试，并且耐心等待：

DShanMCU-RA6M5-DAP-009

一般都是由于访问国外服务器的问题导致的 timed out 错误，此时我们继续运行 python -m pip install -U pyocd 多尝试几次即可：

DShanMCU-RA6M5-DAP-010

可能只需要一次，也可能需要尝试多次，一般在提示出错后重新尝试2-3次可顺利完成，成功界面如下图所示：

DShanMCU-RA6M5-DAP-011
