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 93 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 USB Type-C 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 93 EVK board:

  1. Insert the SD with your QNX IPL, QNX IFS and DTB image files into the selected boot slot on the board (MicroSD slot).
  2. Connect a USB cable from the board's DEBUG UART (J1401) 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 PD port (J301) on the board.
  5. Switch Power Switch (SW301) to ON.
  6. Identify the host serial port on your host system:
    On a Linux 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 93 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 93 EVK board, the boot mode switch is SW1301. After you successfully boot the board with QNX OS, you can prepare it to boot using eMMC.

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, respectively.
Here are the DIP switch settings for the i.MX 93 EVK board:
Boot mode Pin 1 Pin 2 Pin 3 Pin 4
eMMC OFF OFF OFF OFF
SD OFF ON OFF OFF
Serial Boot ON ON OFF 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:
Figure 1SW1301 DIP switch to boot using the SD on the i.MX 93 EVK board


You must configure the following DIP switches for the board as follows:

For SW1005, ensure that you have the 4 DIP switches set to these positions (listed from 1-4): 
ON OFF ON OFF
The following diagram shows how SW1005 should appear on the board:
Figure 2SW1005


For SW1006, ensure that you have the 4 DIP switches set to these positions (listed from 1-4): 
ON OFF ON OFF
The following diagram shows how SW1006 should appear on the board:
Figure 3SW1006


For SW1007, ensure that you have the 4 DIP switches set to these positions (listed from 1-4): 
OFF ON OFF ON
The following diagram shows how SW1007 should appear on the board:
Figure 4SW1007


After you boot the board with an SD, you can use additional steps to boot from eMMC. For more information, see Boot from an eMMC memory device.
