Apart from monitoring the boot process and checking Linux kernel messages for debugging, you can log in to the board through the UART. The configuration parameters of the UART are shown in the following example. Log in to the system with username “root” and password “root.”
- baud rate: 115200 bps
- data bit: 8
- stop bit: 1
- no parity
Note: On a Linux system, you can use Minicom to connect to the target board directly; for a Windows system, a USB to UART driver is needed before connecting to the board through a serial port.
