Configure hardware and boot a reference image

The default image is set up to run the ADAS example application and demonstrates how a system boots to immediately show a video stream from a single camera and sensor data. These are referred to as file cameras and file data, respectively.

Before you boot the reference image on the R-Car H3 Starter board, ensure that the DIP switch settings are configured correctly. For information about setting up the R-Car H3 Starter board, see “Setting up the R-Car H3 Starter board to use the reference image” in this chapter. After you set up the R-Car H3 Starter board, see “Booting the reference image” to understand how to boot the R-Car H3 Starter board.

If you want to connect physical cameras or sensors to the R-Car H3 Starter board, you must change the reference image configuration settings. For more information, see “Connect cameras and sensors” and “Configure sensors and cameras on the reference image” in this chapter.

Setting up the R-Car H3 Starter board to use the reference image

Before you use the R-Car H3 Starter board to boot the reference image, you must configure it to boot from microSD card using the following steps:

If you haven't done so already, connect your R-Car H3 Starter board to:
- a Lilliput 10" display, using the HDMI port on the R-Car H3 Starter board that is closest to the USB ports on the back. (If you use the other port, you don't see the demo after you boot.)
- a USB-serial cable for a console
- the power supply that came from the hardware vendor
The default DIP switch settings on your board should be sufficient to boot the reference image. For more information about the DIP switch settings to set, see “Configure the R-Car H3 Starter board” in the Installation Notes chapter of the Renesas R-Car H3 BSP User's Guide for this release.

Booting the reference image

After you have transferred the image to a microSD card, use it to boot your board. For more information about putting an image on a microSD card, see Prepare a microSD card with an image in the Install and Boot a Reference image chapter of this guide.

Insert the microSD card into the board's microSD card slot.
Press the power button (SW8) on your board.
If you see only one LED enabled on the board, the board isn't powered up yet. Connecting the power or USB cable causes the fan to run, but the board isn't actually powered until you push the power button. The power button is located in the corner of the board near the red and white cables as shown in the following illustration:

You should see that QNX Neutrino boots. However, if it's the first time your board is being booted with a reference image, the following steps needs to be done:
- During the U-Boot countdown, press Enter.
- At the U-Boot prompt, type the following commands:
```
> setenv bootcmd 'fatload mmc 0 0x40100000 qnx-ifs;\
                  fatload mmc 0 0xe6304000 qnx_bootstrap.bin;\
                  go 0xe6304000'
> saveenv
> run bootcmd
```

After the image boots, it runs the ADAS example application by default and uses prerecorded data. If you want to run another application or change the configuration to use cameras or sensors connected to your board, see the Use the Reference Image chapter of this guide for more information.
