最下面看烧录日志原文，脑袋嗡嗡的：

先欣赏一下我做的AI小智多功能开发板，预留全部面包板上没有用到引脚；

用大白话讲明白ESP32-S3固件烧录全流程

    烧录工具选型
    推荐用ESP Flash Download Tool，操作像用微信扫二维码一样简单。

下载解压就行：通过网盘分享的文件：flash_download_tool_3.9.7.rar

第一次打开是这样的；

选芯片型号；

选接口，ESP32S3有两个接口可以下载，一个USB的DP&DN直连IO19,IO20;选图上USB;

另一接口就是用USB-TTL芯片焊在板子上的所谓自动下载电路选UART,多此一举用不到，直接用上面的USB接口好省钱；

   

三、烧录实操篇

    编译生成.bin文件
    在VSCode里点"编译"按钮，生成四个关键文件：
        bootloader.bin （启动程序）
        partition_table.bin （存储分区地图）
        ota_data_initial.bin （升级数据）
        app.bin （你的程序主体）

        srmodels.bin（好像可有可无）

      

    配置烧录参数原文是这样的：

esptool.py --chip esp32s3

-p /dev/ttyACM0

-b 460800

--before=default_reset

--after=hard_reset write_flash

--flash_mode dio

--flash_freq 80m

--flash_size 16MB

0x0 bootloader/bootloader.bin

0x100000 xiaozhi.bin 

0x8000 partition_table/partition-table.bin 

0xd000 ota_data_initial.bin 

0x10000 srmodels/srmodels.bin

对应配置图如下：

        

    开始烧录
    点击"Start"后就像往U盘拷文件，进度条走完就成功了。

    如果卡住，检查USB线是不是假的。

    经实测很多ESP32S3模块由于厂家出厂刷的测试程序关闭了芯片本身的USB串口，那只有用带有自动下载电路的硬件配合BOOT0按键一起下载了，没有任何别的办法。

固件合在一起：

bin文件自动合成

重新选择合成在一起的固件直接烧录，配置地址直接写0就行；

出现这两个才算成功，等待烧录完重启就可以玩了；
