早上还可以下载的。

你先通过STM32Cubeprogrammer连接试试，对STLINK和相关连接做基本确认。


如果这时连接不上，重点检查下STLINK及它与目标板的连接、目标板的供电情况。


若使用TM32Cubeprogrammer连接顺畅，那就重点检查STM32CubeIDE的debugger配置情况。


可以将之前的配置删掉后重建一个。

++补充下：
我刚才使用G0的开发板测试时也遇到类似问题，后来发现是我选项字节有些配置有问题。

STM32cubeide报错，但是使用STM32cubeprogram可以正常烧写程序 (stmicroelectronics.cn)

请问STM32CubeIDE使用STlink下载板子无反应，都排查了一遍没有问题 (stmicroelectronics.cn)

你好。我的目标板是通过micro usb 接口连接的。现在换了好几根线还是连接不上。
