Zoom2 serial is in general supplied by one of the 4 UARTS on the debug board. The default serial is from the USB connector on left side of the debug board. The USB connector will produce 2 of the 4 UARTS. On your host pick the first enumeration.
The serial port set up is the same with Zoom1. Baud rate 115200, 8 bit data, no parity, 1 stop bit, no flow.
The kernel bootargs are console=ttyS3,115200n8
