（我在我的问题中添加了链接，但我会尽可能详细地解释我的问题是什么，这样您就不需要使用这些链接，它们仅供参考）您好，

我正在尝试遵循此 youtube 教程（https://www.youtube.com/watch?v=R6SstBoXjKc&list=PL6PplMTH29SHgRPDufZhfMRoFwRAIrzOp），但他使用 coocox IDE 和 windows。我正在使用 VS Code 和 Ubuntu 16.04.4 LTS。我正在尝试使用 VS Code 的 platformio 扩展以及 stlink-v2 和裸 stm32 f030r8t6 微控制器（https://www.newbiehack.com/categories/newbiehack-microcontroller-ARM-stmicro-STM32F0R6-withBreadboardInterface）。要将我的笔记本电脑连接到开发板，我使用了 st-util 命令，该命令提供以下输出：

    st-util 1.4.0-40-g1ec89bf
2018-07-12T21:28:36 INFO common.c: Loading device parameters....
2018-07-12T21:28:36 WARN common.c: Invalid flash type, please check device declaration

2018-07-12T21:28:36 INFO gdb-server.c: Listening at *:4242...

我的 platform.ini 文件是：

[env:f030r8t6]
platform = ststm32
board = f030r8t6
framework = stm32cube

我创建了一个名为 f030r8t6.json 的自定义配置文件：

{
  "build": {
    "cpu": "cortex-m0",
    "extra_flags": "-DSTM32F030x8",
    "f_cpu": "48000000L",
    "mcu": "stm32f030r8t6"
  },
  "debug": {
    "default_tools": [
      "stlink"
    ],
    "openocd_target": "stm32f0x",
    "svd_path": "STM32F030.svd"
  },
  "frameworks": [
    "mbed",
    "stm32cube"
  ],
  "name": "ST STM32F030r8t6",
  "upload": {
    "maximum_ram_size": 8192,
    "maximum_size": 65536,
    "protocol": "stlink",
    "protocols": [
      "jlink",
      "stlink",
      "blackmagic"
    ]
  },
  "url": "http://www.st.com/en/evaluation-tools/32f0308discovery.html",
  "vendor": "ST"
}

当我构建项目时，一切正常，但是当我尝试上传时，我得到以下信息：

我已经坚持了好几个星期了，非常感谢任何帮助！谢谢！

我猜你在 gpio 主重映射时关闭了代码中的 JTAG 和 SW。当我使用 libOpenCM3 框架编写 stm32 时，像这样的代码： gpio_primary_remap(AFIO_MAPR_SWJ_CFG_JTAG_OFF_SW_OFF, AFIO_MAPR_CAN1_REMAP_PORTB); 会导致像你这样的问题。
