VAR-SOM-MX6 Yocto Jethro Eclipse

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.

Host tools

Build

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

$ cd ~/var-som-mx6-yocto-jethro
$ DISTRO=fsl-imx-x11 MACHINE=var-som-mx6 source var-setup-release.sh -b build_x11

Build the tools:

bitbake meta-toolchain

The build creates the tools installer

$ ls tmp/deploy/sdk/

The outcome should be:

fsl-imx-x11-glibc-x86_64-meta-toolchain-cortexa9hf-vfp-neon-toolchain-4.1.15-1.1.0.host.manifest
fsl-imx-x11-glibc-x86_64-meta-toolchain-cortexa9hf-vfp-neon-toolchain-4.1.15-1.1.0.sh
fsl-imx-x11-glibc-x86_64-meta-toolchain-cortexa9hf-vfp-neon-toolchain-4.1.15-1.1.0.target.manifest

Install SDK

$ tmp/deploy/sdk/fsl-imx-x11-glibc-x86_64-meta-toolchain-cortexa9hf-vfp-neon-toolchain-4.1.15-1.1.0.sh

When system prompts "Enter target directory for SDK (default: /opt/fsl-imx-x11/4.1.15-1.1.0):" hit enter.
When system prompts "You are about to install the SDK to "/opt/fsl-imx-x11/4.1.15-1.1.0". Proceed[Y/n]?" hit y and enter.

At the end of the installation you should see the following:

SDK has been successfully set up and is ready to be used.
Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g.
 $ . /opt/fsl-imx-x11/4.1.15-1.1.0/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi

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

• 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.
