To execute stub code, OpenOCD allocates memory on the target device, backs up the existing memory,
loads the stub binary, runs the binary, and then restores the original memory.
This process can be time-consuming, especially when using USB serial JTAG.
By enabling this option, 8K of memory in RAM will be preallocated with the stub code,
By enabling this option, 12K of memory in RAM will be preallocated with the stub code,
eliminating the need to back up and restore the memory region.

Improve Debugging Speed
^^^^^^^^^^^^^^^^^^^^^^^
Enabling :ref:`CONFIG_ESP_DEBUG_INCLUDE_OCD_STUB_BINS` allocates 8 KB of RAM and embeds pre-built stub binaries into RAM. This improves the overall debugging speed by eliminating the need to load the stub binaries at runtime. It is particularly beneficial when using flash breakpoints, as it reduces the latency of add/remove breakpoints. However, keep in mind that the increased RAM usage may reduce memory availability for other tasks.

提高调试速度
^^^^^^^^^^^^^^^^^^^^^^^
启用 :ref:`CONFIG_ESP_DEBUG_INCLUDE_OCD_STUB_BINS` 将预先分配 8 KB 的 RAM, 且预编译的存根二进制文件将嵌入到 RAM 中，因此运行时将无需加载存根二进制文件，从而提高整体调试速度。在使用 flash 断点时，上述优化可以有效降低添加和删除断点的延迟。但要注意，RAM 使用量的增加可能会占用其他任务所需的内存。
