I think you used the wrong device. I guess /dev/cuaU0 is a real serial port.
But you’re using a usb device, just like me.

screen /dev/ttyUSB0 115200 works for me.

I found the problem. The problem is the non-compatible Radxa USB to TTL Cable with FreeBSD. no output on the serial console. I used other device pro USB to TTL and it works.

I also had many issues with this blue shell UART cable, including driver update that renamed itself to “device driver deprecated and off, contact support” :slight_smile:
The best UART console is CH343 as of my tests :slight_smile:
