Determining the USB Port and Serial ID

This topic explains how to get the USB port number and serial number port settings of your target device. Use this information to configure Minicom, depending on your product.

On Linux hosts, USB serial ports typically appear as:

/dev/ttyACM<number> or /dev/ttyUSB<number>

Where <number> is the port number.

Applies to: Releases supporting Windows:

A host machine may contain internal hardware for serial ports that have no external connector. So, if the host machine contains one normal serial connector in the back of the machine and one hidden internal serial port, then the serial port on the back can appear as /dev/ttyS2 not /dev/ttyS1.

The device USB port numbers and serial IDs are as follows:

  • Aurix Safety MCU: /dev/ttyACM1 for P3710, /dev/ttyUSB1 for P3663
  • Orin: Use the output of the tcu_muxer utility to get the virtual console for the Guest OS. For example, in the example below the Guest OS console is /dev/pts/40.
/dev/pts/7	 RCE
/dev/pts/9	 FSI
/dev/pts/10	PSCFW
/dev/pts/11	DCE
/dev/pts/30	BPMP
/dev/pts/33	SCE
/dev/pts/34	SPE
/dev/pts/38	TZ
/dev/pts/40	CCPLEX: 0
/dev/pts/41	CCPLEX: 1
/dev/pts/43	CCPLEX: 2
/dev/pts/44	CCPLEX: 3
/dev/pts/45	CCPLEX: 4
/dev/pts/46	CCPLEX: 5
/dev/pts/48	CCPLEX: 6
/dev/pts/49	CCPLEX: 7
/dev/pts/50	CCPLEX: 8
/dev/pts/59	CCPLEX: 9
/dev/pts/60	CCPLEX: 10
/dev/pts/61	CCPLEX: 11
################################# 001 ##
  /dev/pts/40 [Guest VM 0]
  /dev/pts/41 [Update service]
  /dev/pts/43 [Resource Manager Server]
  /dev/pts/44 [Storage Server]
  /dev/pts/45 [sysmgr]
  /dev/pts/46 [bpmp_server_native]
  /dev/pts/48 [se_server_native]
  /dev/pts/61 [Hypervisor]

For all ports, the settings should be as follows:

baudrate 115200
bits     8
parity   N
stopbits 1
rtscts   No
xonxoff  No
