Configuring the Eclipse Yocto Plug-in involves setting up the Cross Compiler options and the Target options. The configurations you choose become the default settings for all projects. You have opportunities to change them later when you configure the project (see the following section). To start, you need to do the following from within the Eclipse IDE:
*Choose "Preferences" from the "Window" menu to display the Preferences Dialog.
*Click "Yocto Project ADT".
== Configuring the Cross-Compiler Options ==
To configure the Cross Compiler Options, you must select the type of toolchain, point to the toolchain, specify the sysroot location, and select the target architecture.
*Selecting the Toolchain Type:
Your Toolchanin path should be /opt/poky/1.8. Otherwise point to your build folder.
*Specify the Sysroot Location:
Your Toolchanin sysroots path will be /opt/poky/1.8/sysroots. Otherwise point to your build folder.
This location is where the root filesystem for the target hardware resides.
*Select the Target Architecture: The target architecture will be selected automatically based on your build.<br/>

VAR-SOM-MX6 Programming with Eclipse and Yocto version 3 (Yocto Fido)

Variscite's Yocto release includes the required packages to the build images fsl-image-qt5 with Eclipse debug support. This guide will describe how to use Eclipse to develop applications to run on the VAR-SOM-MX6.
Detail information can be found:

previous version

Host tools

Build

Change directory to your build directory and verify that your environment settings is set correctly.

$ . ./setup-environment build_x11/

Build the tools:

bitbake meta-toolchain

The build creates the tools installer

$ ls tmp/deploy/sdk/

The outcome should be:

ls tmp/deploy/sdk/
poky-glibc-x86_64-meta-toolchain-cortexa9hf-vfp-neon-toolchain-1.8.sh
poky-glibc-x86_64-meta-toolchain-cortexa9hf-vfp-neon-toolchain-1.8.manifest

Install SDK

$ tmp/deploy/sdk/poky-glibc-x86_64-meta-toolchain-cortexa9hf-vfp-neon-toolchain-1.8.sh

When system prompts "Enter target directory for SDK (default: /opt/poky/1.8):" hit enter.

When system prompts "You are about to install the SDK to "/opt/poky/1.8". Proceed[Y/n]?" hit Y and enter.

An installation log should look like:

variscite@baba:~/var-som-mx6-yocto-fido/build_x11$ tmp/deploy/sdk/poky-glibc-x86_64-meta-toolchain-cortexa9hf-vfp-neon-toolchain-1.8.sh 
Enter target directory for SDK (default: /opt/poky/1.8): 
The directory "/opt/poky/1.8" already contains a SDK for this architecture.
If you continue, existing files will be overwritten! Proceed[y/N]?y
[sudo] password for variscite: 
Extracting SDK...done
Setting it up...
done
SDK has been successfully set up and is ready to be used.

Eclipse installation

Please follow : https://community.freescale.com/docs/DOC-172840

Create and run a simple application

Create the Project

You can create two types of projects: Autotools-based, or Makefile-based. This section describes how to create Autotools-based projects from within the Eclipse IDE. To create a project based on a Yocto template and then display the source code, follow these steps:

  • File->New->C Project
  • Click Yocto Project ADT Project.
  • Select Hello World ANSI C Autotools Project. This is an Autotools-based project based on a Yocto template.

  • Put a name in the Project name: field. Do not use hyphens as part of the name.
  • Click "Next".
  • Add information in the Author and Copyright notice fields.
  • Be sure the License field is correct.

  • Click "Finish".
  • If the "open perspective" prompt appears, click "Yes" so that you in the C/C++ perspective.
  • The left-hand navigation pane shows your project. You can display your source by double clicking the project's source file.
  • "hit Ctrl B" It will build your project.

Create communication link

Using the console of your target set a password with "passwd" command. choose a simple one named "root". The target should be connected to the network via Ethernet or WIFI. Use the "ifconfig" command to get the target ip address. From Eclipse

  • Window->Open Perspective->Other
  • Double click on Remote System Explorer

  • In the left bar right click and New->Connection
  • Choose TCF and Next

  • Set the Host name to the target IP

Tcf3.jpg

  • Hit Finish
  • On the left bar right click on the taget IP and select connect
  • Set "User ID:" to root, "Password:" to root and check the "Save password"

  • enter the root password again in the next poop up.

Once connected you can browse target file system, browse target process and lunch a terminal to the target.

Remote debug

Follow the below steps to remotely debug your application on the VAR-SOM-MX6.

  • Select "Debug Configurations..." from the "Run" menu.
  • In the left area, expand C/C++Remote Application.
  • Locate your project and select it to pop up a new tabbed view in the Debug Configurations Dialog.
  • Enter the absolute path which you want to deploy the application to. Use the "Remote Absolute File Path for C/C++Application:" field. For example, enter /home/root/hello

  • Click on the "Debugger" tab to see the cross-tool debugger you are using.
  • Click on the "Main" tab.
  • Hit Debug
  • Accept the debug perspective.
