In this complete step-by-step guide, we will showcase a start-to-end mechanism for your Eragon820 Development Kit.

First, let’s start with the basic appearance:

After it’s opened, the first thing you should see is a Quick Start Guide that gives complete overview of Eragon820 Development Kit. Along with Quick Start Guide, you will find eInfochips Support and Warranty pulicy card. 

Here you can see the Eragon820 Development Kit inside a static bag along with all the accessories.

Here, you can see a few additional contents in the package contents:

  • Eragon820 Development Kit
  • 12V Power supply
  • UART serial cable
  • RJ45 Ethernet cable

Here is the Eragon820 Development Kit:

Getting Started with Eragon820 Development Kit:

By default, Android 6.0.1 Marshmallow release is pre-flashed in all the ERAGON820 boards. The developers can use the release just that way, or re-flash the board with the prebuilt binaries available in the release package.

Please follow the steps mentioned below when you receive the ERAGON820 Development Kit for the very first time:

  • Remove the ERAGON820 board carefully from the anti-static bag.
  • By default, Boot configuration mode Switch (SW1) in Eragon820 Board is set to UFS Boot mode “0010” as depicted in the table below.

    • If you want to boot Eragon820 Board from eMMC or if you have eMMC variant mounted on the Board, then you need to make Boot configuration switches (SW1) to “0100” as depicted in the table below.

  • Connect one end of the HDMI cable to the connector J8 on ERAGON820 board, and the other end to HDMI Display as depicted in the following figure:

  • Connect 12V power adaptor to the ERAGON820 Board as depicted in the following figure:

  • The board will begin to boot-up, upon pressing the Power On Switch (SW2) as depicted in the following figure:

  • After a few seconds, Android Boot logo followed by the lock screen will be displayed on the HDMI Display as depicted in the following diagrams.

Connecting with UART Debug Cable:

UART Serial cable is already shipped with Eragon820 Development Kit. Follow the steps mentioned below to connect Eragon820 Development Kit with UART Serial Cable.

  • UART Serial cable is shipped with Eragon820 Development Kit. It looks like these:

  • Connect UART Serial cable on J27 connector on Eragon820 Carrier Board as depicted in the following figure.

  • Set up the serial terminal in your Host PC with Baud rate settings as 115200 8-N-1 with no Hardware and Software flow contrul.
  • Connect 12V power supply with Eragon820 Board. The board will begin to boot up upon pressing power on switch (SW2) and you will be able to see debug messages on serial terminal as depicted in the following figure.

Eragon820 Development Kit Power on indications:

LED_2 and LED_3 is incorporated in Eragon820 SOM for Power on Indications.

When 12V Power supply is connected to DC jack of Eragon820 Board, then LED_3 will glow as depicted in the following figure. It means that all the necessary PMIC power supplies are up-and-running.

Upon pressing Power on switch (SW2), LED_2 will be turned on and LED_3 will be turned off as depicted in the following figure. It means that the Eragon820 Development Kit is up-and-running.

This is Eragon820 Development Kit in ready-to-use configuration. To know more, drop us an email at marketing@einfochips.com or visit this link.
