Genio 520 EVK Demo Requirements

This demonstration kit is very flexible and can be setup in various configurations, with software support for Android. However for the purpose of this Quick Start Guide, a specific configuration is chosen with the following conditions:

Android software build
D8/D9 Camera Board enabled

Additional Items Needed for Quick Start Guide Demo

To support the demo, the following additional items are needed.

Two USB Cables (USB-2.0-A to Micro-B)
External PC for loading flash and interacting via command prompt

Setup PC Environment

Install the Genio Tools on your Linux or Windows PC.

Kit Hardware Installation

Insert the D8/D9 Camera Board to CAM0/CAM1 on the main motherboard.

Connect UART0 to the computer via a USB Type-C cable as shown in the image USB Port Locations below:(If you want to see the logs).

This requires installation of the Google Android USB driver as outlined in the Setup PC Environment section. If using Windows, open Device Manager and confirm that the driver appears under Android Device \ Android Bootloader Interface.

set the jumper on J516, then insert the DC 20V power adapter or USB Type-C PD adapter.

Long press PWR button for more than 3 seconds. You will see the screen is shown on MIPI DSI display and some trace logs coming out from UART0

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

Connect to the Serial Console

Setup the serial port for viewing debug output and interacting with the kit through a command line interface.

Check Device Manager that the USB COM port appears as a UART device under COM Ports
Configure your installed serial terminal emulator to use the serial port corresponding to the devices UART0 and operating with the baud rate set to 921600.

../_images/Example-on-Putty.png — Example with Putty

Use dmesg to determine which USB serial ports have recently been connected:

dmesg | grep tty
[299443.861514] usb 2-4.2.1: FTDI USB Serial Device converter now attached to ttyUSB0

In this instance, the serial terminal is ttyUSB0, which will be present under /dev/

Connect to the device using a baud rate of 921600, for example, with Picocom:
```
picocom -b 921600 /dev/ttyUSB0
```

Flash the Software

This guide shows how to “flash” (write) the demo image into the non-volatile flash memory of the main motherboard. The flashing process is performed through the USB0 connection. 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.

Download the pre-built private board image to your local PC.

Note

Be sure to download the private image as it is required to run the demos in this quick start guide.

Unzip the image.

Note

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 Image to Board instructions for further details or troubleshooting.
Once you see the Looking for a MediaTek SoC ... prompt, start the process to boot the board in flash download mode.

Press and keep pressing the Download button.
Press and release the RST button
Hold the Download button until you see the log Erasing 'mmc0' message, as shown below:

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

Genio Tools: v1.7.0a2

    WARNING:root:Unable to find and reset the board. Possible causes are:
    1. This is not a Genio 350/700 EVK, nor a Pumpkin board.
    2. The board port UART0 is not connected.
    3. The UART0 port is being opened by another tool, such as TeraTerm on Windows.
    You can now manually reset the board into DOWNLOAD mode.

Note

The above command should be the only needed to flash the image with the configurations necessary in this Quick Start Guide. Further background and troubleshooting information including different command options are available in Flash Image to Board. A common problem is that the download does not start and simply keeps waiting for the device. More information is available in Missing Android Device Driver.

Once the kit boots up with the new flash image, debug log messages can be seen through UART0 in the Putty terminal window.
