** OpenOCD初始化失败**使用VS Code，platformio，stlink v2和stm32 f030r8t6

Question

（我在问题中添加了链接，但我将详细解释我的问题是什么，以便您无需使用链接，它们仅供参考） 嗨，

我正在尝试遵循此youtube教程（https://www.youtube.com/watch?v=R6SstBoXjKc&list=PL6PplMTH29SHgRPDufZhfMRoFwRAIrzOp），但他使用的是coocox IDE和Windows。我正在使用VS Code和Ubuntu 16.04.4 LTS。我正在尝试将VS Code的platformio扩展与stlink-v2和裸露的stm32 f030r8t6微控制器（https://www.newbiehack.com/categories/newbiehack-microcontroller-ARM-stmicro-STM32F0R6-withBreadboardInterface）一起使用。要将笔记本电脑连接到板上，请使用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

我的platform.ini文件是：

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

然后我创建了一个名为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"
}

构建项目时，一切正常，但是当我尝试上传时，得到以下信息：

我已经坚持了好几个星期，真的很感谢您的帮助！ 谢谢！

我猜您在gpio主重新映射时关闭了代码中的JTAG和SW。 当我使用libOpenCM3框架编写stm32时，代码如下： gpio_primary_remap(AFIO_MAPR_SWJ_CFG_JTAG_OFF_SW_OFF, AFIO_MAPR_CAN1_REMAP_PORTB); 会引起像您一样的问题。
