4SETTING UP THE SYSTEM
Below are the steps need to followed for setting up the system
1. Fix the M3 screws and Spacers to the EVAL board
2. Fix the M2 spacer and nut for mounting the LCD
3. Place the LCD on the acrylic and connect the FPC cable to the receptacle (J9) and lock the cable
4. Fix the M2 screws.
5. Configure the required boot option using DIP switches.
6. Insert the coin cell to the battery holder
7. Connect the SD card
8. Connect the Debug UART .
9. Connect the required peripherals
10. Using the DC jack( J1) Power the board from a 5V, 5A adapter.
4.1 Fixing the EVAL Board on M3 spacers
Fix the EVAL board on four M3 spacer and screw as shown below
Figure 4 :Fixing the M3 spacers

4.2 Fixing the acrylic for LCD
After placing EVAL board please fix the M2 spacers, M2 nuts, on this we can place the acrylic piece on
which LCD glued. Using the M2 screws fix the LCD.

User can connect the FPC cable of the LCD to the J9 FPC connector. Please lock the cable by pushing the
black coloured lock towards the connector.
Figure 7: Connecting FPC cable
4.4 Changing the BOOT option
The default boot device of the EVAL board will be SD card. Boot device can select using switch SW6. Boot mode
can select from switch SW7. To change the boot device to eMMC along with the SW6, SW7 change please mount
resistor R221 with 10K and remove the resistor from pad R248.
4.4.1 Boot option for SW6

Table 2: SW7 Boot option
Please make sure to set the boot options to SD as shown in below figure.
Figure 8: SD Boot configuration.
User can refer below figure to configure eMMC card boot option. Resistor change also needed for eMMC
boot

4.5 Inserting the uSD card
User can flash the uSD card with boot image and that can insert to the Connector J2. It is a push-in Push-
out uSD connector. Please refer the below figure for connecting uSD card.

4.6 Inserting the coin cell
User need to insert a CR2032 coin cell to the battery holder BH1 for the battery backup and proper working
of all functionality. Please refer below figure to insert the coin cell.
Figure 11: Inserting coin cell
4.7 Connecting Debug UART
For getting console access, a USB micro-B cable needed. Micro-B end need to insert to the Connector J8.
The other end of the cable can be connected to the PC USB port. Please refer below figure.

4.8 Connecting USB cable.
User can use connector J7 for connecting OTG device or usb cable. USB cable can connect to the board as shown
below.
Figure 13:Connecting USB cable
4.9 Connecting the User Interface Devices (Optional)
Below are the User Interfaces which can connect to our board. And all these devices are optional
1. USB2ANY
2. Ethernet
3. JTAG Header
4. GPIO Header

TIXU_MX6Y Rev. A1_02

4.9.1 USB2ANY
Connect the USB2ANY 10 pin cable to the header H1 as shown below. Please make sure the Key of the connector is
aligning with silk screen marking.
Figure 14: Connecting USB2ANY header
4.9.2 Ethernet
100BASE-T Ethernet communication is supported through the dual port RJ45 jack J3. Connecting LAN cable is
shown below
Figure 15: Connecting Ethernet cable

TIXU_MX6Y Rev. A1_02

4.9.3 JTAG Connector
User can use header H5 for the JTAG communication. Segger J-link Base is compatible with this 2.54mm 20 pin
header.Please connect the J-link Base as shown below.
4.9.4 GPIO Header
User can access 10 gpios from the header H4. This is for user defined purpose.
4.10 Powering the board
User can use a 5V, 5A adapter to meet the power requirement of the EVAL board. There is a DC power
jack J1 for the power input. After inserting the DC plug of the adapter to the jack please use switch SW1 to turn on
the power.
Figure 16: Connecting adapter.
