Hello @eliaspromiseq,
Unfortunately the Ivy Carrier board does not expose the serial debug console by default.
This interface is only exposed via a USB transceiver in the Verdin boards intended for development only (Verdin Development Board, Dahlia Carrier Board, and Yavia).
In the Ivy Carrier Board you can still access the debug UART, but you need to populate an unpopulated header and use a USB to UART TLL adapter.
As you can see on the schematics, you can use a 3.3V TTL signal on J1 or a 1.8V TTL signal on J17:
Please note that the schematics snippet above is for Ivy V1.0A.
Best Regards,
Bruno
