ESP32 Forum

Hi there,

I have a ESP32S2 module on a custom PCB and I was already able to upload some code to the module. However, I was having trouble building new projects, so I reinstalled everything and now I can't upload the code to the module. I get this issue:

Terminal will be reused by tasks, press any key to close it.

Also, on the device manager, the ESP32S2 appears with a yellow triangle indicating some problem with the drivers. I'm using Windows 10 64 bits with the latest updates.

Make sure drivers are configured correctly as specified in https://docs.espressif.com/projects/esp ... ction.html

It was a combination of using Zadig to fix the drivers to WinUSB and a folder with a space that was making the upload fail. It's working now, thank you.

Can you share details on your setup? I'm looking for a solution to getting ESP-IDF, the VSCode extension and an ESP32-S2 board to work with native USB-CDC. Is this possible?

Thanks,

Hi, yes, it is possible as I am using it right now. However - it's a nightmare to configure correctly and I need to resort to a simple demo project that I keep copying. Unfortunately it contains some stuff I can't share, so I will only answer the last question - From Visual studio - View->Command Palette "ESP-IDF: SDK Configuration Editor (menuconfig)"

Then search for "CDC" and you will see the following settings that you can enable, and then the console log will go through the native USB connector without needing to add code for it.
For the first flashing of your program you need to add the special drivers as described by others and hold down the "boot" button while resetting. The comports number do changes between these two settings, which is annoying, but it do work.
