ESP32 Forum

Hi

Hope you are all doing well.
I took the new product "ESP32-C6_DevKitC-1 N8", and I connected its UART by A to C USB to the PC, tried a lot to send and receive AT commands, but it did not work. I also tried to flash the module but had an "Invalid head of packet (0x47): Possible serial noise or corruption." error message.
Are there any instructions we must do to make this product work?

Thank you

There's likely no AT code in that devboard by default, so it's no surprise that doesn't work. What specifically (OS, software) are you using to flash it?

Thanks for your response!

My OS is “Windows 10 Pro”, and I am trying to flash it using “ESP32C3 FLAH DOWNLOAD TOOL V3.9.3” as it is the newest version “since I could not find a software tool for the ESP32C6”.


I also tried both “ESP-IDF Eclipse” and “Espressif-IDE” with the most basic code “Hello World”, and changed the connection; once by the A to C USB, and once by the model’s Tx& Rx pins (using USB to TTL; 3.3v for Vin), but I obtained an error message like this:
"
Connecting....

A fatal error occurred: This chip is ESP32-C6 not ESP32. Wrong --chip argument?

CMake Error at run_serial_tool.cmake:55 (message):

NOT: I have two “ESP32-C6_DevKitC-1” modules, tried them both, but did not work.

This chip is ESP32-C6 not ESP32

There's your error: you have something (the flash tool?) set up for an ESP32 and you're flashing an ESP32C6. Not sure how exactly you would change that in the GUI tool but if that's impossible, perhaps you can use the command-line tool for this?

Same problem for me. I using Eclipse 2022-09 on Ubuntu 20.04
