I have connected a FTDI TTL-232R-3V3 USB to UART Cable with +3.3V TTL Level UART Signals cable to an Orin Nano, using only the TX and RX lines. Minicom and PuTTY (both with no flow control) running on Ubuntu 22.04LTS nicely show the entire boot sequence, ending with a login prompt - BUT I can’t login; typing has no effect using either appt. Is this the expected behavior?
Minicom configuration:
Welcome to minicom 2.8
