You may start by referencing the USB CDC ACM sample in Zephyr. It should be possible to integrate the functionality from this into your Thread application.

Ah I've built it on the nrf52840dk_nrf52840, how could I get started with serial port communication on the nrf52840dk_nrf52840?

Hi,

This sample is intended for the nRF52840 on the Thiny:91, for converting HW UART messages to USB CDC packets. It does not sound like the best starting-point for your use-case.

Did you build the sample for the thingy91_nrf52840 target, or for the nrf52840dk_nrf52840?

Best regards,
Jørgen

It seems to be the

uart_irq_update(dev);

function call on line 99 of main.c where the error occurs
