* The input parameter is the preset firmware path. If multiple paths are input, each path needs to be separated by `,` and a maximum of 3 firmware paths can be input. For new versions, use the standalone tool to burn presets. See [firmware_update_tool Tool](../6_benchmark/firmware_update_tool.md). * The input parameter is the preset firmware path. If multiple paths are input, each path needs to be separated by `,` and a maximum of 3 firmware paths can be input. This parameter is only for burning or upgrading preset firmware; after burning, set `device_preset` to switch to a preset. For new versions, use the standalone tool to burn presets.
