      - Before You Begin
        Before you begin working with this BSP, you should become familiar with the resources available to you.
      - About This BSP
        These notes list what's included in the BSP, and identify the host OSs and boards it supports.
      - Installation Notes
        These installation notes describe how to build, work with, and run this BSP.
        Download and set up the BSP
        You can download Board Support Packages (BSPs) using the QNX Software Center.

        System Layout
        The following is the memory layout required for the Xilinx KD240.
        Prepare a bootable microSD card
        You can prepare a bootable microSD card on a Linux, or Windows host system. We recommend that you use Class 10 (or UHS-1) microSD cards.
        Prepare a bootable microSD card using Raspberry Pi Imager
        You can use Raspberry Pi Imager to install Pi OS to a bootable microSD card on a Linux or Windows host system. We recommend that you use Class 10 (or UHS-1) microSD cards.
        Transfer the image
        After you prepare a bootable microSD card, you're ready to transfer the image to it and change the system configuration file config.txt to boot QNX IFS image.
        Boot the board
        After you transfer the image to an microSD, you can use it to boot your board.
      - Build the BSP
        You can use the QNX Momentics IDE or the commandline on Linux or Windows to build an image.
      - Driver Commands
        The tables below provide a summary of driver commands for the Xilinx KD240.

Set up the hardware

Connect the hardware

In addition to the board, you require these cables:

USB to TTL serial cable
an Ethernet cable
5V DC power cable

CAUTION:

Use only the power supplies provided with the board. Use of any other power supply may permanently damage the board. When power cycling the board, turn the power on or off from the AC adapter side, rather than removing and inserting the DC power plug on the board, to prevent damaging the board’s power-regulation circuitry.

To connect the Raspberry Pi 4 board:

Insert the microSD card with your QNX IFS image file into the selected boot slot on the board.
Connect a USB to TTL serial cable from the board's serial pins and the USB port on your host machine.
Figure 1Serial pins on the 40-pin GPIO expander header (J8)
- J8 pin6: GND
- J8 pin8: GPIO14 (UART_TXD0)
- J8 pin10: GPIO15 (UART_RXD0)
Connect the Ethernet cable to the Ethernet jack on the board.
Connect the board's 5V DC power supply to the POWER IN (USB-C) connector on the board.
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 (COMand LPT) section. Then, look for a COM port named Gadget Serial or USB Serial Port.
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
