vscode Cortex-Debug 与 stm32l0 发生异常

如何解决vscode Cortex-Debug 与 stm32l0 发生异常

我想使用 VSCode Cortex-Debug 来调试 stm32l071 项目。 首先我用STM32cubeMX构建了一个简单的项目。 我发现在调试的第一行（重置处理程序）发生了异常。 而且如果偏移起始地址，程序似乎会崩溃。

我通过修改ld文件的FLASH的ORIGIN和system_stm32l0xx.c中的VECT_TAB_OFFSET来偏移程序的起始地址，看来程序计数器在第一行之后就变得奇怪了，无法运行到main。但是如果我尝试使用 OpenOCD 和 gdb 命令行，程序可以运行到 main 并正常工作。另外如果我不偏移地址，在异常之后程序仍然可以正常工作。

我的launch.json如下

{
    "showDevDebugOutput": true,"cwd": "D:\\Tools\\openocd","executable": "${workspaceRoot}/Debug/2460P_testST.elf","name": "Debug STM32","request": "launch","type": "cortex-debug","servertype": "openocd","device": "STM32L071CB","configFiles": [
        "interface/stlink.cfg","target/stm32l0.cfg"
    ]
}

以下是我的开发环境
电脑：Windows 10
OpenOCD：0.11
VSCode：1.55.2
皮质调试：0.3.12
ST-Link v2

也许调试控制台能帮上忙，贴如下
