ESP32 C6 Not able to program, Packet content transfer stopped

[WadoAdi]

Hi All,
I have up to now been using an ESP32 C6 Zero board from WaveShare and programming it via the Arduino IDE, selecting board as ESP32 C6 Dev Module. I recently had a board made with the ESP32 C6 Chip directly on my board. When programming it, I get the following error:

Sketch uses 223601 bytes (17%) of program storage space. Maximum is 1310720 bytes.
Global variables use 12784 bytes (3%) of dynamic memory, leaving 314896 bytes for local variables. Maximum is 327680 bytes.

And then the command prompt hangs.

What do I need to do before I can program the chip in the normal way using the IDE, do I need to burn a boot loader or something?

Many thanks for any help or advice.

That's usually an issue with the flash. Did you design in a flash chip on your board, or are you using an ESP32C6 variant with internal flash?

That’s a great question! I hope it’s internal flash! But now I’m thinking we have the wrong chip!

So it looks like we used a chip with no onboard flash oooops

Thanks for your help
