Failed to connect to ESP32-C2: Invalid head of packet (0x12): Possible serial noise or corruption.

Postby vrambo8 » Mon Dec 02, 2024 11:29 pm

I have a custom chip with an ESP8684-WROOM-02UC, I have been following this https://docs.espressif.com/projects/esp ... setup.html for flashing a sample application onto the chip. But when I try to flash the firmware onto it, I always receive the data corruption error in the title: Invalid head of packet (0x12): Possible serial noise or corruption.

I have tried multiple baud rates, and I have also tried establishing a serial connection through screen or PuTTY, I always get gibberish as an output. I have tried using a CH340G usb-uart adapter, then I changed to a CP210x adapter. No luck.

I am starting to think the chip has hardware issues, though I don't know much about it, I'm a software person but no hardware experience. Does anybody know what I could do?

Thank you in advance
