我正在尝试设置一个 Eclipse 开发环境来使用 stm32f303 nucleo 32 板。 http://www.st.com/en/evaluation-tools/nucleo-f303k8.html
到目前为止,所有工具似乎都已正确安装和工作:我已经成功编译并启动了用于 stm32f4 发现的 openocd 调试器,当我连接 stm32f303 nucleo 32 板并启动 openocd 时,板上的 LED 指示它已连接。(我已经刷过板了。)
当我逐步调试时,openocd 迷路了,这似乎与 openocd 在启动时给我的消息有关(寻找粗线):

是否有人知道在这种情况下如何修复 USB 驱动程序,或者其他原因可能导致问题?
