Using ESP32-C3 QT Py with Zephyr RTOS?

[tamberg]

Hi,

I'm trying to get the Adafruit QT Py ESP32-C3 WiFi Dev Board [0] to work with Zephyr RTOS.

The ESP32-C3 Dev Module seems to be supported [1].

However the hello world [2] does not seem to work.

Compiling and flashing seems to work, but there's no serial output.

UART Pins seem to be the same on the QT Py, according to pinout [3].

Is there any other substantial difference between the QT Py and Dev Module?
