Some components are missing from this module (marked in red). I don't know if they are mandatory

This is 01, the chip is from 03 module. It does not work

ESP8684-WROOM-01C-H2

ESP8684-WROOM-03-H2


This is the 03 module with the replacement chip

The picture shows modules 01 and 03. We have replaced the chips in some places. Module 01 is not programmed again with chip 03, and module 03 works with chip 01. In other words, the problem is in the module components and assembly. We tried to replace the quartz of module 01 with quartz of 03. But t...

“Serial communications are very sensitive to noise. Adding a capacitor (e.g. 10 µF electrolytic and 0.1 µF ceramic) close to the ESP8684 module power pins can help smooth out any voltage fluctuations.” The customer tried this but the issue was not resolved

Here is the schematic

这是原理图

这是带有更换芯片的03模块
这是01，芯片来自03模块。它不工作
此模块中缺少某些组件 (标记为红色)。我不知道它们是否是强制性的

Could you please specify what pins you used for flashing code into ESP?
In my case I used (RX, TX, 3V3, GND, EN and IO0).

发生致命错误：无法连接到 ESP32-C2：数据包头无效 (0xE3)：可能存在串行噪声或损坏。 此外，我尝试使用 idf.py 和 Espressif IDE 进行刷新，但在两种情况下都遇到了类似的问题，导致代码刷新失败。 系统设置： 芯片型号：ESP8684-WROOM-01C 开发环境：ESP-IDF v5.2.2 USB 转串行适配器：USB-Enhanced-SERIAL CH9102 电源：3.3V 稳压电源 采取的故障排除步骤： 验证 TX、RX、3.3V、GND、GPIO0 和 EN 引脚的连接。 确认重置期间 GPIO0 保持低位以进入引导加载程序模式。 尝试以多种波特率（1...
