Specifying Flash Image
~~~~~~~~~~~~~~~~~~~~~~
By default, QEMU uses the ``qemu_flash.bin`` file in the build directory as the flash image. This file is generated based on the information available about the project from the ``flash_args`` file present in the build directory. If you want to use a different flash image file, you can specify it using the ``--flash-file`` option. For example,
.. code-block:: console
idf.py qemu --flash-file my_flash.bin monitor
The provided flash image must meet the following requirements for proper emulation:
- The flash file size matches the value specified by :ref:`CONFIG_ESPTOOLPY_FLASHSIZE` in the project configuration.
- The flash file includes all required binaries, such as the bootloader, partition table, and application firmware, placed at their respective memory offsets.
