GDB cannot open serial ports accessed as COMx, can not get IP address using ethernet example
Posted: Sun Mar 28, 2021 9:38 am
Hi,
I am using OS Win10, VS Code EPS-IDF extension and Olimex ESP32-PoE (Rev. B) board, and struggling with these two problems.
The first is, that when I flash the ethernet-basic example code from ESP-IDF folder (where I defined power pin for Eth PHY), I get this warning:
GDB cannot open serial ports accessed as COMx, as shown below:

The second problem is, that I can't get IP address to ping to my board. I have used ethernet example from Olimex website too, but both examples gave me exactly the same result (below is continuation of previous code):
