Debug Port Setting
Connect Type A end of TTL-232R-RPI cable to PC and 3pin (100mil) Berg House end of TTL-232R-RPI cable to Debug UART Header (J5) as shown below.
Use one of the terminal application depending on the operating system of the host machine:
- On the command prompt of the Linux host machine, run the following command to determine the port number:
$ ls /dev/ttyUSB* - The smaller number is for Arm® Cortex®-A53 core and the bigger number is for Arm® Cortex ®-M4 core.
Minicom
Use the following commands to install and run the serial communication program (minicom as an example):
- Install Minicom using Ubuntu package manager.
$ sudo apt-get install minicom - Launch Minicom using a console window using the port number determined earlier.
$ sudo minicom -s - Configure Minicom as show in below figure
- Next step is to Power ON the board.
