[参考译文] MSPM0C1104：MSPM0C1104问题–程序跳转到 COPY_ZERO_INIT

https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1483515/mspm0c1104-issue-with-mspm0c1104-program-jumps-to-copy_zero_init

工具与软件：

您好！

我目前正在使用 MSPM0C1104 (16引脚 SOT)微控制器开发一个项目、在执行过程中遇到问题。 我已经在我的项目中配置并启用了以下外设：

GPIO：PA0、PA2、PA6 (配置为输出)
ADC：已在应用中配置和使用
UART：配置用于通信
我已附加我的 syscfg 文件以供参考。

问题描述
执行代码时、程序意外跳转到函数 copy_zero_init。 通过调试,我发现在调用 SYSCFG_DL_init ()内的 GPIO 启用功能后立即发生这种情况。 不过、当我在单独的新工程中配置 GPIO 时、它会正常工作、这表明这个问题特定于我的当前设置。

对 copy_zero_init 的观察结果
在分析 copy_zero_init.c 文件后、它似乎负责在启动期间将全局/未初始化变量初始化为零。 这表明我的程序可能会遇到意外触发此初始化的问题。

请求协助
您能否就以下方面提供指导：

为什么在 SYSCFG_DL_init ()中启用 GPIO 后,程序执行跳转到 COPY_ZERO_INIT ?
syscfg 文件中是否存在可能导致此问题的任何潜在错误配置？
如何执行调试步骤来进一步找出根本原因？
