Custom POE Esp32 - the serial tx path seems to be down

Postby Eren069 » Tue May 07, 2024 11:44 am

Hi,
I am currently working on a high school project and need your help regarding a custom POE Esp32 board. I’ll get this error when I try to flash something :

the serial tx path seems to be down

The PCB design is copied from ESP32 Olimex POE.

What I am doing wrong with the USB-C connection ?

Can you stick an oscilloscope on the Rx of the ESP32, see if the signal comes through?
