Reference for the delivered components:

Power On

If not in a cased unit, follow these steps:  Align the golden fingers
of the Core Board (with the main chip facing upwards) with the slot on
the Baseboard, then press down on the Core Board, ensuring the locking
clips on both sides securely fasten.  Connect the fan power to the FAN
interface (near the power interface). Place the cooling pad on the
center of the heatsink, then attach the fan to the main chip, ensuring
the cooling pad covers the entire chip.

Connect the 12V-5A power adapter and plug it into a 100~220V AC power
source. Insert the other end of the power cable into the power
interface of the development board.

The development board will power on automatically upon being connected
to power.

Remote Network Login

Ethernet port 0 (near the serial port) is configured with DHCP, while
Ethernet port 1 (near the HDMI port) is configured with a static IP
"192.168.150.1", subnet mask "255.255.255.0". You can set your PC's IP
to "192.168.150.2/24" for initial access.

If you can successfully "ping" the network interface IP, you can
proceed to log in via "ssh". The port number is "22", and the username
and password are both "linaro":

   ssh linaro@192.168.150.1

Once connected to the development board, you can modify the network
configuration similarly to Debian/Ubuntu desktop versions by
configuring files in the "/etc/network/interfaces.d/" directory.

Serial Terminal Access

Power Off

When shutting down, it's recommended to avoid directly disconnecting
the power. First, run "sudo poweroff", then disconnect the power to
avoid damaging the file system data.

Additionally, if you've successfully entered the Linux system, you can
also press and hold the power button. The system will detect it and
safely shut down the system and the development board's power.
