ESP32S3 n16r8, no print on monitor

Other Hardware 3rd Party Boards

Esp32s3 is booting, but it seems not to excecute the program, or no prints are sent. I tested 2 units , but cannot get it to work. Cdc flag is set, use the com port. Is there a suggested settings file somewhere ? The device is esp32s3-wroom 1, and use arduino 3.2.6

Thanks for any suggestion

Two different things. If you upload Blink, does it execute?

That sounds like the basic ESP32S3 module, but to use it its normally mounted on a board with a heap of other components.

So which actual ESP32S3 board are you using ?

Some ESP32S3 boards have two USB connections, do you have one of them ?

Good idea to post a link to the actual board you are using, less confusion …………………

Which port on the ESP32S3 Devkit board are you connecting your USB cable to?

I presume by this you mean Tools -> Use CDC On Boot: Enabled ?

5

Yes of course, and use com port, not the usb one.

6

It is the module using esp32s3 wroom1, N16R8, with 2 usb-c connectors com and usb, I use com port

7

despite I read on the internet that cdc needs to be enabled at boot, I had to disable it and now it works

It needs to be enabled if your uploading via the native USB port and disabled if your using the Serial com port. At least that’s the case for my ESP32S3 development boards.
