rt-studio使用DAP-link不成功

使用DAPLink，发现无法debug，也无法下载，会报如下错误：

这家伙很懒，什么也没写！

我发现问题了，rt-studio带的pyocd0.1.6存在bug，他可能会将stm32f405芯片，识别为L4系列的芯片，我更换了ulink，就可以debug了，然后换了另一个板子，上面还是f405，daplink也可以使用。现在看来，某些情况下，pyocd不太可靠。

使用pyocd + daplink 下载 STM32H7 也有问题 https://club.rt-thread.org/ask/question/4ece0057dce4d2dc.html

这个问题到现在也还没有明确解决方法。
我真的要破口大骂，什么破studio，连daplink下载程序都搞不定。

临时措施：我目前通过按住复位，点击下载后松开复位的方式，可以完成下载。

不按复位直接下载的命令行输出内容如下
