Likely something went wrong with flashing the firmware. Can you tell how you flashed it? Are you sure you selected the correct firmware for the chip? (E.g. esp32 vs esp32-c3)

<t>Hi everyone,<br/>
<br/>
I've been researching the ESP32-C3 flashing circuit and have designed a basic circuit for flashing the ESP32-C3 SMD board. However, when I try to flash the basic blink example code, I encounter the following error: "COM5 failed to connect: Failed to connect to Espressif device: No serial data received."<br/>
<br/>
I've also attached the PCB design for reference.<br/>
<br/>
Any advice on how to resolve this issue would be greatly appreciated.</t>
