Set up the hardware

Before you can work with the board, here are a few things you must do. You'll need to connect the board and set the DIP switches. For more information, see the hardware guide for the i.MX 8MP EVK board on the NXP website.

Connect the hardware

In addition to the board, you require these cables:
  • a USB 2.0 A-Male to Micro-B cable
  • an Ethernet cable
CAUTION:

Use only the power supply provided with the board. Use of any other power supply may permanently damage the board.

To connect the i.MX 8MP EVK board:

  1. Insert the SD with your QNX IPL and QNX IFS image file into the selected boot slot on the board (MicroSD slot).
  2. Connect a USB cable from the board's DEBUG UART (J23) to the USB port on your host machine.
  3. Connect the Ethernet cable to the Ethernet jack on the board (J7).
  4. Connect a USB Type-C power supply to the PORT0 connect on the board.
  5. Switch Power Switch (SW3) to ON.
  6. Identify the host serial port on your host system:
    On a Linux host, you can check which port is the host serial port by looking at what port appears when the cable is inserted. To do this, type the command: 
    $ ls /dev/ttyUSB*

    On a Windows system, open the Device Manager and expand the Ports (COM and LPT) section. Then, look for a COM port named Gadget Serial or USB Serial Port.

  7. Connect to the COM port using your favorite terminal program with these settings:
    • Baud rate: 115200
    • Data: 8 bit
    • Parity: none
    • Stop: 1 bit
    • Flow control: none
    • Serial Device: /dev/ttyUSB2

Set DIP switches on the i.MX 8MP EVK board

If this is the first time you're booting the board, you need to set the boot mode switch to boot using an SD. On the i.MX 8MP EVK board, the boot mode switch is SW4. After you successfully boot the board with QNX OS, you can prepare it to boot using eMMC or xSPI NOR Flash memory.

Note:
On the boot mode switch, the boot mode number labels are located above the DIP switches. In the following table, ON means that the switch is set to the top position, while OFF means the switch is set to the bottom position on the SW2, respectively.
Here are the DIP switch settings for the i.MX 8MP EVK board:
Boot mode Pin 1 Pin 2 Pin 3 Pin 4
Fuse OFF OFF OFF OFF
Serial Boot OFF OFF OFF ON
eMMC OFF OFF ON OFF
SD OFF OFF ON ON
Octal xSPI NOR Flash OFF ON ON OFF
To boot your board for the first time, you must set the switches to boot from an SD as shown in the following illustration:

After you boot the board with an SD, you can use additional steps to boot from eMMC or xSPI NOR Flash. For more information, see Boot from an eMMC memory device and Boot using xSPI NOR flash, respectively.
