Description of kit contents

Genio 350 EVK Main Motherboard

The image shows the main mother board and relevant IO.


Genio 350-EVK main motherboard interfaces

AP1302 ISP Camera Board, Appletec AR0430 Camera Module, and mini-SAS cable

Each AP1302 ISP Camera Board can be connected to the main mother board with a mini-SAS cable. An AP1302 ISP Camera Board supports two possible MIPI CSI paths:

  • Connect directly with the processor (MT8365) on the Genio 350 EVK main motherboard

  • Connect with the main board through an ISP (On-Semiconductor AP1302CSSL00SMGA0-DR)

These two MIPI paths are switched by a MIPI multiplexer (TI TS3DV642RUARQ1) which is controlled by the correct jumper selection and cabling. The small small device pictured below is the Appletec AR0430 Camera Module and it features the OnSemi AR0430 image sensor.

Further details regarding both USB drivers can be found in the flash trouble-shooting section.

  • Plug AC/DC power adapter into the connector.


Power Adapter Installation


After the EVK power is turned on, confirm that the four LED indicators illuminate.

Flash the software

This guide shows how to “flash” (write) the demo image into the non-volatile flash memory of Genio 350-EVK. The flashing process is performed through the USB0 connection on the Genio 350-EVK. In order to write the on-board storage with Genio Tools, you need to set the IoT SoC in download mode, which allows Genio Tools to transfer a download agent binary to the SRAM of SoC. The download agent then provides a fastboot interface for subsequent image transfer and storage write operations.


Avoid having a long path name by installing to a root folder and shortening the file name if necessary, for example C:\evk.

  • Open a Windows cmd window (to enter commands)

  • Change working folder to the image directory before running the genio-flash commands:

cd C:\evk
  • View the Flash Genio 350-EVK instructions for further details or troubleshooting.

  • Flash the image using the overlay which enables both cameras. which enables Before flashing the board, check if there are certain board features you’d like to enable:

genio-flash --load-dtbo camera-ap1302-ar0430-dual.dtbo
  • Once you see the Looking for a MediaTek SoC ... prompt, start the process to boot the board in flash download mode.

  1. Press and keep pressing the volume up button

  2. Press and release the reset button

  3. Release the volume up button


Reset the board to enter download mode


On most Genio evaluation boards, the volume up button is connected to the KPCOL0 pin of the chip. If you have trouble finding the correct button, refer to the user guide or schematics of your board.

You should see flashing process started after releasing the volume up button. A typical successful log looks like this:

Camera Demo

The Genio 350-EVK Yocto Demo uses an imaging configuration using the Onsemi AR0430 and the Onsemi AP1302.

Camera Setup

  • Set jumpers on AP1302 ISP Camera Board

There are six jumpers which must be configured as shown in the above figure of the AP1302 ISP Camera Board and Appletec AR0430 Camera Module.

  • Set camera properties with media-ctl command

Before using the cameras, you must set the resolution and the pixel format to 2316 * 1746, UYUV using the media-ctl command. The command requires several parameters, one of which is the media device of the sensor. The index of the media device may differ depending on the probing order of drivers and the number of devices. You can determine the index of the media device by typing the following command. In this example, the media device is /dev/media1.

ls -l /sys/bus/media/devices/ | grep seninf
lrwxrwxrwx 1 root root 0 Sep 20  2020 media1 -> ../../../devices/platform/soc/15040000.seninf/media1

Type the following commands to set the format of the MIPI-CSI0 camera:

media-ctl -d /dev/media1 -V "'ap1302.2-003d':2 [fmt:UYVY8_1X16/2316x1746]"
media-ctl -d /dev/media1 -V "'15040000.seninf':4 [fmt:UYVY8_1X16/2316x1746]"
media-ctl -d /dev/media1 -V "'15050000.camsv':1 [fmt:UYVY8_1X16/2316x1746]"

Type the following commands to set the format of the MIPI-CSI1 camera:

media-ctl -d /dev/media1 -V "'ap1302.3-003d':2 [fmt:UYVY8_1X16/2316x1746]"
media-ctl -d /dev/media1 -V "'15040000.seninf':5 [fmt:UYVY8_1X16/2316x1746]"
media-ctl -d /dev/media1 -V "'15050800.camsv':1 [fmt:UYVY8_1X16/2316x1746]"

Show camera images on the screen

You must determine which device nodes are for the cameras. The video device nodes which point to seninf are the cameras. In this example, the cameras are /dev/video3 and /dev/video4.

ls -l /sys/class/video4linux/ | grep seninf
lrwxrwxrwx 1 root root 0 Sep 20 10:44 v4l-subdev0 -> ../../devices/platform/soc/15040000.seninf/video4linux/v4l-subdev0
lrwxrwxrwx 1 root root 0 Sep 20 10:43 video3 -> ../../devices/platform/soc/15040000.seninf/video4linux/video3
lrwxrwxrwx 1 root root 0 Sep 20 10:43 video4 -> ../../devices/platform/soc/15040000.seninf/video4linux/video4

Using the video device nodes determined above, use the gst-launch-1.0 command to cause the cameras to display live video on the HDMI monitor.

gst-launch-1.0 v4l2src device=/dev/video3 ! video/x-raw,width=2316,height=1746,format=UYVY ! v4l2convert output-io-mode=dmabuf-import ! video/x-raw,width=400,height=300 ! fpsdisplaysink video-sink=waylandsink sync=false &
gst-launch-1.0 v4l2src device=/dev/video4 ! video/x-raw,width=2316,height=1746,format=UYVY ! v4l2convert output-io-mode=dmabuf-import ! video/x-raw,width=400,height=300 ! fpsdisplaysink video-sink=waylandsink sync=false &

You should see both camera images as shown below.


Multi-camera images using GStreamer

These commands are started in the background by using the ampersand symbol at the end of the command. To end any of these processes, you can type fg to place the process in the foreground, then CTRL+C to end it. Before proceeding to the next demo, type

GPU Demo

On IoT Yocto, there are several OpenGL ES applications that can used to check that the GPU is running and well integrated within the Wayland/Weston system. In this section we introduce two GLES applications: weston-simple-egl and kmscube. They both use the GPU to render content, but they have different approaches to creating their graphic windows.

Display a rotating cube

This is a simple GLES program demonstrating how to drive bare metal graphics without a compositor (wayland), using DRM/KMS (kernel mode setting), GBM (graphics buffer manager), and EGL for rendering content using OpenGL ES.

After having typed CTRL+C from the above step, you should see only the simple desktop window which shows the date and time in the upper right hand corner. This desktop graphic is being driven by the weston service. In this demo, we will display a rotating cube by running the kmscube command. However kmscube will create its own window on which it renders content. So, before we launch kmscube, we must make sure that no other window system occupies the display. This means stopping the weston process that drives the desktop.

  • Stop weston service if it already started.

    killall weston
  • Confirm that the desktop disappears and you see only a dark screen on the HDMI monitor.

  • Launch kmscube and confirm that you can see a rotating cube as shown in below figure.


Screenshot of kmscube

  • Type CTRL+C to stop displaying the rotating cube.

Display a rotating triangle

This is a simple demonstration GLES program that draws a rotating colorized triangle on a transparent Wayland window. This program is not responsible for creating the window, and instead merely renders its content on an existing window which weston creates. So, before launching it, we must start weston.

  • Start weston service if it is not started yet.

    systemctl start weston@root.service
  • Confirm that the desktop reappears which shows the date and time in the upper right hand corner.

  • Launch weston-simple-egl and confirm that you can see a rotating triangle as shown in below figure.

    153 frames in 5 seconds: 30.600000 fps
    150 frames in 5 seconds: 30.000000 fps
