ESP32-DevKitC开发板（搭载WROOM-32D模块）AT固件烧录失败

[without]

买的ESP32-DevKitC开发板，搭载WROOM-32D模块，烧录AT指令失败。
步骤：
1，选择配置
chipType 选择了ESP32D2WD，workMode选择了develop。
2，SPIDownload选择的是ESP32-WROOM-32-V2.2.0.0/factory/factory_WROOM-32.bin，地址是0，SPISpeed选择40MHz，SPI MODE选择DIO，勾选DoNotChgBin，选择的是Default。
3，点击START后，按开发板右侧的上电按钮，提示信息：11-configure spi cmd fail，命令行窗口显示的内容是：SEND ESP SPI ATTACH CMD
[2022-02-19 09:19:37,264][ESP8266Loader_spi[1]][espDownloader.py][line:618][ERRO
R]: ESP32D2WD ConfiguredSPICmdError esp_config_spi_mode.
no log file output ...

麻烦大家帮忙看下，多谢多谢！

你的模组是 WROOM-32D 的，你的 chipType 应该选择 ESP32. ESP32D2WD 的 flash 是 2MB 的，不可以烧录 4MB 的 WROOM-32 的固件的.

感谢。按照上面说的固件烧写成功。验证AT命令时，没有响应。我是用和烧录一样的串口发送的AT命令，这个是要使用GPIO13和GPIO15进行AT命令通信吗？

ESP32 AT的命令口和烧录口是不同的. 您可以看一下这篇文章 ESP32 WROOM 模组使用 AT 固件硬件应该如何连接：https://docs.espressif.com/projects/esp ... html#esp32

你好，我分别用TTL、RS232试了GPIO16和GPIO17，还有开发板上标着RX、TX的引脚，其他的引脚也尝试了，也修改了不同的波特率，连续发送AT的时候，有时候回复乱码，串口没有响应正常，请问这个该怎么排查？多谢。

[ESP_Sun]

AT 默认固件的波特率是 115200，您的 GPIO 16 要连接在 TTL 的 TX, GPIO17 要连接在 TTL 的 RX 上，您可以直接用波特率 115200 打开烧录口，手动按开发板的 RST 键，您看一下烧录口是否有 log 打印。对于您看我们的 AT 文档的硬件连接（https://docs.espressif.com/projects/esp ... n.html#id1）以及下载指导（https://docs.espressif.com/projects/esp ... e.html#id1）部分文档，您觉得有哪里需要改进的地方吗？

可以正常连接了，之前引脚接错了，多谢。
