 +===== SSH connection on STKa8Xx =====
 +
 +<WRAP round important>Please keep in mind that the following instructions focus on simplicity, not on security.</WRAP> 
 +
 +<WRAP round info>For the sake of simplicity password authentification can be used for SSH.</WRAP>
 +
 +=== Setup Yocto build environment ===
 +
 +The OpenSSH sftp server is not installed into the image by default, add the following to your local.conf to install it.
 +
 +<code>IMAGE_INSTALL_append = “openssh-sftp-server”</code>
 +
 +
 +=== Setup on Target ===
 +
 +To setup a password for the default user root, 
 +execute the command **passwd root** and set your password.
 +
 +=== Modify SSH configuration ===
 +
 +Uncomment the following options in **/etc/ssh/sshd_config** to allow that the user root can authenticate 
 +with a password on the STKa8Xx.
 +
 +<code>PermitRootLogin yes
 +PasswordAuthentication yes
 +</code>
 +
 +===== Setup Qt Creator with Yocto build environment =====
 +
 +==== Building Yocto SDK ====
 +
 +Building the toolchain requires a Yocto build environment configured for meta-tq or ci-meta-tq 
 +The setup of the build environment is described on the corresponding Yocto quickstart of the module. 
 +
 +<WRAP round important> The meta-qt5 Yocto layer has to be added to the Yocto build environment when using meta-tq</WRAP> 
 +
 +After the Yocto build environment the SDK can be built by the following command:
 +<code>bitbake meta-toolchain-qt5</code>
 +\\  
 +<WRAP round info>Building meta-toolchain-qt5 may take several hours, depending on your hardware configuration</WRAP>
 +
 +
 +
 +==== Installing Yocto SDK ====
 +
 +After building meta-toolchain-qt5 the SDK file is located in the following path of the build directory **tmp/deploy/sdk/fsl-imx-wayland-glibc-x86_64-meta-toolchain-qt5-aarch64-toolchain-4.14-sumo.sh**  
 +
 +Execute the *sh file to install the SDK, the default path is set to **/opt/fsl-imx-wayland/4.14-sumo**
 +
 +==== Set Up Qt Creator ====
 +
 +Download [[https://download.qt.io/archive/qt/5.10/5.10.1/qt-opensource-linux-x64-5.10.1.run|Qt Opensource 5.10.1]]\\
 +After downloading make the Qt installer file executable and run the Qt installer. Follow the installation wizard instructions.\\
 +
 +The next step is to add the environment setup of the Yocto SDK to the first line (above the shebang) of the file qtcreator.sh script.\\
 +If the install location has not been changed the qtcreator.sh is located in **~/Qt5.10.1/Tools/QtCreator/bin/qtcreator.sh**
 +
 +<code>source /opt/fsl-imx-wayland/4.14-sumo/environment-setup-aarch64-poky-linux</code>
 +
 +==== Run Qt Creator ====
 +
 +change to the directory where the qtcreator.sh file is located and execute the following command: 
 +<code>sudo sh qtcreator.sh</code>
 +
 +<WRAP round important>If qtcreator.sh returns source: not found, before sudo sh qtcreator.sh, enter sudo dpkg-reconfigure dash and choose no.</WRAP>
 +
 +
 +==== Configure Qt creator ====
 +
 +=== Setup SSH connection ===
 +
 +  - Go to **Tools > Options > Devices** 
 +  - Click **Add > Generic Linux Device > Start Wizard**
 +  - Change the name to "STKa8Xx" and set up the connection.
 +
 +{{:en:general_information:yocto_qt_ssh.png?nolink&800|}}
 +
 +
 +
 +
 +
 + <WRAP round info>Click Test to test the network connection of the target device.</WRAP>
 +
 +=== Add compiler ===
 +
 +  - Go to **Tools > Options > Build & Run> click Compilers**
 +  - Click **Add** and select **GCC**
 +  - Change Name to **TQMa8Xx**
 +  - Set **Compiler path** to  /opt/fsl-imx-wayland/4.14-sumo/sysroots/x86_64-pokysdk-linux/usr/bin/aarch64-poky-linux/aarch64-poky-linux-g++
 +  - Set the following values for **ABI** from the dropdwon menus:
 +
 +^  processor architecture  ^  operating system  ^  OS flavor  ^  binary format  ^  system architecture  ^
 +|  arm  |  linux  |  generic  |  elf  |  64bit  |
 +
 +
 +{{:en:general_information:yocto_qt_compiler.png?nolink&800|}}
 +
 +=== Add new Cross Compiled Qt Version ===
 +
 +  - Click **Qt Versions** on the **Build & Run** panel
 +  - Click **Add**
 +  - Locate the qmake file in /opt/fsl-imx-wayland/4.14-sumo/sysroots/x86_64-pokysdk-linux/usr/bin/qt5/qmake
 +<WRAP round info> If the qmake file has been auto-detected by Qt Creator qmake has not to be added manually.</WRAP>
 +
 +{{:en:general_information:yocto_qt_qmake.png?nolink&800|}}
 +
 +=== Add new Kit ===
 +
 +  - Click on **Kits** in the **Build & Run** panel
 +  - Click **Add** and set the following:
 +
 +**Name** STKa8Xx\\  
 +**Device Type** Generic Linux Device\\  
 +**Device** STKaXx (default for Generic Linux)\\  
 +**Sysroot** /opt/fsl-wayland/4.14-sumo/sysroots/aarch64-poky-linux\\  
 +**Compiler** STKa8Xx\\  
 +**Qt version** Qt 5.10.1\\

 +==== Hello World Application ====
 +
 +  * Open **File** menu and click **New Project**
 +  * Select **Qt Console Application**
 +  * Specify the location for the project and name it hello_world
 +  * Select the Kit STKa8Xx 
 + 
 +
 +  * Edit main.cpp
 +<code>
 +#include <QCoreApplication>
 +#include <iostream>
 +#include <stdlib.h>
