I’m attempting to attach a USB camera into the Jetson Nano, but nothing is being detected in the serial ports (I’m using pyserial). I found the following method to check what the serial ports are, and this code runs, but it outputs that there aren’t any serial ports, which is confusing because the Jetson obviously has serial ports. I’m wondering why no serial ports are being detected, and how I could make it so they are detected and usable.
import sys import glob import serial def serial_ports(): """ Lists serial port names :raises EnvironmentError: On unsupported or unknown platforms :returns: A list of the serial ports available on the system """ if sys.platform.startswith('win'): ports = ['COM%s' % (i + 1) for i in range(256)] elif sys.platform.startswith('linux') or sys.platform.startswith('cygwin'): # this excludes your current terminal "/dev/tty" ports = glob.glob('/dev/tty[A-Za-z]*') elif sys.platform.startswith('darwin'): ports = glob.glob('/dev/tty.*') else: raise EnvironmentError('Unsupported platform') result =  for port in ports: try: s = serial.Serial(port) s.close() result.append(port) except (OSError, serial.SerialException): pass return result if __name__ == '__main__': print(serial_ports())
