ESP32 Wrover Kit: 2 COM ports available

Hi,

I’m new to ESP32 Wrover Kit.

I managed to build my first ESP32 Wrover Kit Platform from the documentation (GitHub - MicroEJ/Platform-Espressif-ESP-WROVER-KIT-V4.1: MicroEJ Platform for Espressif ESP-WROVER-KIT V4.1)

I also successfully managed to build the BSP.

Now I want to program the firmware, by following these instructions GitHub - MicroEJ/Platform-Espressif-ESP-WROVER-KIT-V4.1: MicroEJ Platform for Espressif ESP-WROVER-KIT V4.1

However, at step 2 “Take a look at the new COM port available”, I’m confused because when I plug my device I get 2 new COM ports with the same description:

Any idea on that ?
Which one should I configure in the run script settings file ?

Thanks for your help,

Lucas

Hello @lfleuve ,

Yes the USB port mounts two virtual serial links on your computer. One is the standard output, the other is a connection to the JTAG, as described here: ESP-WROVER-KIT V2 Getting Started Guide — ESP-IDF Programming Guide v3.2.2 documentation

On your computer if you open the properties of the devices you will see a channel A and B in the location field, for example:

So A should be used for the traces and B for the programming of the board.

Hope it helps!
