Step by step guide to your first android app (DACU)

Info Box Applies to Android Applies to Dacu

Introduction

This tutorial shows how to develop your first Android application and run it on the DACU platform.

Boot the system

Let's assume the system is configured to boot loading the kernel and root file system from the internal flash.

Start the system as described in the Running Android in "normal mode" section.

Change the default ip address

If the default ip address is not suitable for your network configuration, you need to modify it. The first thing to do is to connect the null-modem serial cable to the J3 connector

Dacu serial cable

and start your preferred terminal emulator, as described in the Running Android in "full control mode" section.

On the u-boot console, please enter the following command to check the default ip address:

=> print ipaddr                                                                                                    
ipaddr=192.168.0.122                                                                                               

To change the ip address, please enter the following commands:

=> setenv ipaddr <enter-new-target-ip-address>                                                                                                          
=> saveenv

Protected 1 sectors                                                                                                
Protected 1 sectors                                                                                                
=>
