使用 QT Creator 调试 STM32

Question

我决定尝试使用带有 ARM GCC 工具链的 Qt Creator。我设法设置了一个 QBS 项目，它已构建并且固件已成功下载。另外，我在板上使用STM32F3-Discovery和STM32F303VCT。但我无法调试项目，原因如下：

1. 断点不起作用。过程不会停止。
2. 我无法进入源文件，只能在反汇编程序中。当我尝试进入 Main.c 时，Qt Creator 切换到 Disassembler 本身。

如何设置调试器以查看寄存器、添加 Watch、设置和清除寄存器中的位，例如在 Keil 或 Eclipse 中？那么，有人可以帮忙吗？谢谢。 附言这是我的 Start.qbs

Answer 1

显然，您为调试模式配置了错误的优化设置。变量 cpp.debugInformation 在编译器启动时设置，基于在 QtCreator 中选择的编译器模式。我会替换代码

Properties
{
    condition: qbs.buildVariant === "debug"
    cpp.defines: outer.concat(["DEBUG=1"])
    cpp.debugInformation: true
    cpp.optimization: "none"
}

Properties
{
    condition: qbs.buildVariant === "release"
    cpp.debugInformation: false
    cpp.optimization: "small"
}

到下一个：

Properties {
    // Debug
    condition: cpp.debugInformation
    cpp.defines: outer.concat(["DEBUG=1"])
    cpp.optimization: "none"
}
// Release
cpp.optimization: "small"

我的这段代码运行良好。
