我在vscode 的 esp-idf 插件下使用gdb调试 esp32s3时，程序无法在断点 app_main 处停下，会直接运行 flash中的应用程序。
请教一下 esp32s3 的gdb 无法在断点处停下的原因是什么？
环境如下：
主机环境： ubuntu20.04
开发环境： vscode + esp-idf v5.3.2 插件(5.3 release版本)
硬件环境： 立创实战派ESP32-S3开发板
详细描述：
需求：想使用gdb调试一下 https://github.com/espressif/esp-idf/t ... rted/blink 这个应用程序。
编译工程时已经正确设置了工程的 target 为 esp32s3.
当使用 esp-idf 插件 工具栏中的 Debug 工具调试时，发现程序无法在断点处停下来。
于是手动输入调试命令，现象一样，仍然无法停下来，gdb 的调试信息如下：
