ESP32-S2-WROOM 模组如何接线烧写固件

堂三赞

最近入手了一块ESP32-S2-WROOM模组,只因其IO端口多，想做个多功能的小玩具，怎奈水平太LOW，现在又遇到问题了，网上也搜索了下，浏览了官方的相关手册，只因技术太差，也没找到解决方法，就向论坛里的老师们请教了
按照目前了解的资料，做的接线图如下：
烧写器                                  ESP32-S2-WROOM
3V3-----------------------------------VCC
RST---------
EN-------------------------------------EN
TXD-----------------------------------TXD0
RXD-----------------------------------RXD0
IO0---------                                       IO0---------------GND
IO2---------                                       
GND----------------------------------GND
                                                         IO46--------------GND
                                                         IO18----10KΩ----3V3

GND是共地的
用安可信串口调试助手 V1.2.3.0  连接后有如下信息：

发送的AT命令没有反馈字符，看这些信息，用自己蹩脚的英语理解下，好像芯片在不断的重启
这种状况下也无法刷固件。

现在已经解决，按这个方法接线没错，ARDUINO IDE里 安装好ESP32S2的开发板后就可以上传程序了。
