ABOUT THE i.MX 8XLITE EVALUATION KIT
The i.MX 8XLite applications processor is a member of the i.MX 8 family, providing a range of cost-performance scaling, high levels of software reuse and a dedicated Hardware Security Module (HSM) targeting automotive telematics and vehicle-to-everything (V2X) applications.
Its flexible architecture allows both high performance and low power consumption, as well Time-Sensitive Networking (TSN) makes the i.MX 8XLite SoC suitable for a wide variety of industrial applications, such as infrastructure and building control.
Further resources are available on i.MX 8XLite PSP including hardware design files, software tools, board support packages (BSPs) for Linux® , freeRTOS™, and documentation on the i.MX 8XLite application processor.

SETTING UP THE SYSTEM
The following will describe how to run a Linux image on the i.MX 8XLite EVK.
Confirm Boot Switches
The boot switches should be set to bootfrom the SD Card. See table below andconfigure the Boot switch SW1:
| BOOT DEVICE | SW1 | ||
| USHD1 SD | BOOT_ MODE[2] |
BOOT_ MODE[1] |
BOOT_ MODE[0] |
| 0 | 1 | 1 | |
1=ON 0=OFF
Setting up the System SD Card
Insert the MicroSD card into socket J6 on the EVK CPU Board.
Connect USB Debug Cable
Connect the micro-B end of a USB cable into debug port J19. Connect the other end of the cable to a PC acting as a host terminal. On Windows, 2 UART connections will appear on the PC. The console print will output on “Enhanced COM port,” which can be found in “Device Manager” of the PC. On Linux, 4 UART connections will appear. Two of them are used as serial console. The serial port drivers for the debug port connection can be found on this webpage: https://www.ftdichip.com/Drivers/VCP.htm.
Open the terminal window (i.e., Hyper Terminal or Tera Term), choose the COM port number that corresponds to the “Enhanced COM port” on Windows or the ttyUSBx for Linux which corresponds to the serial console, and apply the following configuration.
- Data bits: 8
- Baud rate: 115200
- Stop bit: 1
- Parity: None
- Flow control: None
Connect Ethernet Cable (Optional)
Connect an Ethernet cable to the Ethernet Jack J8 (close to the Debug port).
Wi-Fi/Bluetooth Module (Optional)
Connect the M.2 form factor Wi-Fi Bluetooth module with E-key to the M.2 Connector J17.
Connect Power Supply
Connect the plug of the 12V power supply to the DIN connector J1. When power is connected to the EVK, it will automatically begin the boot sequence.
CAUTION: To avoid damage, do not hot plug the daughter cards while the CPU card power is ON
BOOT PROCESS FOR LINUX® IMAGE
Boot Process
- Switch SW1 to ON, ON, OFF, ON (from 1-4 bit) to boot from the SD card, as shown in Figure 4. The first three switches named “0”, “1”, “2” are used to choose the BOOT mode. The last one named “SYS_ID_WP” is used for write protection of the System ID memory (the ON position, by default, prevent write operation to such memory).
- Power on the EVK board.
- During the boot process, there will be console prints on the terminal window of the PC (if connected).
- To work from the terminal window on the host PC, press ‘Enter’ at the terminal window to get the command prompt. Account name: root, password none.
DIP SWITCH CONFIGURATION
