几年来,我一直在使用 mbed 在线编译器来创建 .bin 文件,然后像这样使用 ST-LINK/V2 USB 加密狗在命令行中刷新它们,一切正常:
st-flash write 01_blink.NUCLEO_F103RB.bin 0x8000000
今天我下载了 STM32CubeIDE for Linux (Fedora 30) 并开始学习本教程,使用的是 maple mini (STM32F103CBT6)。
构建项目并开始调试运行后,我得到输出:

之后我无法再启动调试会话,因为我得到了这个:
我可以看到 LED 按预期闪烁,所以我知道程序实际上已经闪到板上了。但是我无法对 STM32CubeIDE 做任何进一步的事情,当我像以前一样尝试通过命令行进行闪存时,现在这也不起作用:
[root@localhost Downloads]# st-flash write 01_blink.NUCLEO_F103RB.bin 0x8000000
st-flash 1.5.1-38-gc3577b5

幸运的是,我可以通过使用 ST-Link UTILITY(在 Windows 上)并在连接前按住重置按钮返回我的起点,然后进行完全擦除,如此处所述:

但显然,这不是完成任何生产性开发的可行情况。我究竟做错了什么?
在“调试配置”对话框的“调试器”选项卡中,我尝试将“接口”设置为 SWD(实际上已经如此),并且我还尝试了“重置行为”的所有选项,结果没有任何变化。
