SB-UCM-iMX8: HOWTO: USB Console

Setting up your host PC

1. Make sure that the micro-USB cable is properly connected between the SBC console connector to a USB port on your host PC.
2. Make sure the CP2104 driver is available with your operating system, otherwise install CP2104 driver onto the host PC from https://www.silabs.com/documents/public/software/CP210x_Windows_Drivers_with_Serial_Enumeration.zip
3. Identify the host PC interface and port number that will be used for communication with the SBC:
   • In most Linux PCs, the serial port will be denoted as one of the following (where n is a positive integer): /dev/ttyUSB0, /dev/ttyUSB1 ... /dev/ttyUSBn
   • In Windows PCs, the serial port usually will be denoted as one of the following (where n is a positive integer): COM1, COM2 ... COMn
4. Start a terminal emulation program (such as HyperTerminal on Windows or minicom on Linux).
5. Within the terminal emulation program, in the serial port configuration section select the port identified in previous step and set the following serial port parameters:

Baud Rate	Data Bits	Stop Bits	Parity	Flow Control
115200	8	1	none	none

Setting up the Compulab Board

1. Start the system by enabling power through the main DC power connector.
2. Console messages should appear on your host PC through the terminal emulation program.
