[参考译文] TMS320F280049C：通过 python3脚本运行 DSS 文件的部分内容、同时不丢失 debugSession 详细信息

https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1374235/tms320f280049c-running-parts-of-a-dss-file-through-a-python3-script-while-not-losing-the-debugsession-details

工具与软件：

下面所述的代码是一个 JS 文件、在将其与 DSS 配合使用时能够按预期工作。 但我想将 JS 函数集成到我拥有的一个更大的 Python 应用程序中。

例如、我想创建一个调试会话、连接到电路板并加载程序、之后 python 应用程序将执行必要的测试、然后应该会运行 JS 文件中的 Stack 使用函数。

我曾尝试使用 Jython、但 Jython 脚本需要通过 Jython 命令运行、而不能通过 Python3运行、该命令会在代码中保留、但在运行部分代码时会丢失会话详细信息。

请建议我通过 python 脚本运行各个 JS 函数、同时保持 debugSession 有效。
