SETTING UP THE SYSTEM
The following steps will describe how to
run the pre-loaded Android image on the
i.MX 8M Mini LPDDR4 EVKB.
1Confirm Boot
Switches
The boot switches should be set to boot
from the eMMC. See table below.
BOOT DEVICE SW1101 SW1102
eMMC/uSDHC3 0110110001 0001010100
1 = ON 0 = OFF
2Connect USB
Debug Cable
Connect the micro-B end of a USB cable
into debug port J1701. Connect the other
end of the cable to a PC acting as a host
terminal. Two UART connections will appear
on the PC, one for the M4 core, one for the
A53 core. The console print will output on
“enhanced COM port,” which can be found
in “Device Manager” of the PC.
If the serial port is not recognized,
download and install updated drivers as
listed in the section titled, “Debug Serial
Console.”
Open the terminal window (i.e., Hyper
Terminal or Tera Term), choose the COM
port number that corresponds to the
“enhanced COM port” or the highest
numbered port and apply the following
configuration.
• Baud rate: 115200
• Data bits: 8
• Parity: None
• Flow control: None

3Connect
HDMI Display
The MIPI-DSI to HDMI accessory card and
Mini-SAS cable are needed for evaluating
HDMI.
Connect the Mini-SAS cable to J801
on the EVKB (MIPI DSI Connector) and
connect the other end to J5 on the MIPI
to HDMI accessory card. Connect an
HDMI cable to J2 (HDMI port) on the
MIPI to HDMI accessory card and connect
the other end to a HDMI display panel.
Figure 4: Mini-SAS cable connected to
the Mini-SAS connector (J5) on the MIPI-
DSI to HDMI accessory board. Note:
Color may differ.
Warning: Do not plug-in or remove the Mini-SAS devices
while the board is powered on. This may cause damage
to the board and devices.
4Connect
Mouse
Connect the mouse to J301 (USB Type-C
Port 1) through the USB Type-C to A
adapter.
5Connect
Power Supply
Connect the USB Type-C plug of the
power supply to J302 (USB Type-C Port
2), then power up the board using switch
SW101.
Use only J302 for power delivery to the
board.
6Board
Boot Up
As the board boots up, you will see 4
penguins appear in the upper left-hand
corner of the monitor, and then you will
see the Android logo before you see the
Android desktop. Congratulations, you
are up and running.
