      - Before you begin
        Before you begin working with this BSP you should become familiar with the resources available to you when building QNX embedded systems.
      - About this BSP
        This chapter lists what's included in the BSP, the supported host system operating systems, and other relevant information to use this BSP.
      - Installation Notes
        These installation notes describe how to use this BSP to boot your board with the QNX OS.
        Download and set up the BSP
        You can download Board Support Packages (BSPs) using the QNX Software Center.
        Connect the hardware
        Attach the USB and other cables to the appropriate hardware connectors.
        Prepare a bootable microSD
        You can prepare a bootable microSD on a Linux or Windows host system. We recommend that you use Class 10 (or UHS-1) microSDs.
        Preparing the microSD to boot the board
        You can prepare your microSD to boot using U-Boot.
        Boot using U-Boot
        Booting from OSPI
      - Build the BSP
        You can use the QNX Momentics IDE or the commandline on Linux or Windows to build an image.
      - Configure the Screen Graphics Subsystem
        The default buildfile (kd240.build) that's provided with this BSP doesn't build an image that starts the Screen Graphics Subsystem (Screen). Instead, you must use the image that's built from the j721e-evm-graphics.build file, which starts Screen automatically.

Connect the hardware

Attach the USB and other cables to the appropriate hardware connectors.

Connectors

The following ports, connectors and buttons are of most interest when you begin working with your Jacinto 7 J721E EVM board. To connect and work with the hardware, you need to do the following:

ensure that the DIP Switches SW3, SW8, SW9, and SW13 are set properly. For more information, see the Configure the board switches section in this chapter.
connect the provided USB to serial cable to the J44 connector on the board
if you want to run graphics on your board, connect your monitor with a DisplayPort cable to Display0 on the board.
Note:
DisplayPort-to-DVI or DisplayPort-to-HDMI adapters don’t work with DisplayPort. An active DisplayPort-to-HDMI adapter is needed to connect to an HDMI device.
plug in the 12V (5A) DC board power supply (provided separately from the board).
CAUTION:
Ensure that you use the power supply that came with your board (if applicable). Using any other power supply may damage your board.

The location of the RJ45, USB-serial, and DisplayPort connectors are shown in the following illustration of the board:

Figure 1Connectors for the Jacinto 7 J721E EVM

For more information about the board, see the Jacinto7 DRA829/TDA4VM Evaluation Module (EVM) User's Guide at http://www.ti.com/lit/pdf/spruis4 on the Texas Instruments website.

Configure the board switches

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

For EVM Configuration Switch (SW3), ensure that you have the ten DIP switches set to these positions (listed from 1-10):

OFF ON OFF OFF OFF OFF ON OFF ON OFF

The following diagram shows how SW3 should appear on the board:

Figure 2SW3

For the Main Boot Mode Switch (SW8), ensure you have the set to these positions (listed from 1-8):

ON OFF OFF OFF OFF OFF ON OFF

The following diagram shows how SW8 should appear on the board:

Figure 3SW8

For the Wakeup Boot Mode Switch (SW9), ensure you have the set all the switches to the OFF position. The following diagram shows how SW9 should appear on the board:

Figure 4SW9

For the EMU SW Switch (SW13), ensure you have the set all the switches to the OFF position. The following diagram shows how SW13 should appear on the board:

Figure 5SW13
