The following instructions are based on DHCOM STM32MP1 computer on module and Yocto version "zeus"


Prepairing your virtual machine

Get the Virtual Machine for Application Development.

Install the following package: 

$ sudo apt-get install qtcreator qt5default

Download and install the SDK package

Get the QT5 SDK for STM32mp1

Unpack the archive and install the toolchain. 

$ sh ./dhlinux-glibc-x86_64-meta-toolchain-qt5-cortexa7t2hf-neon-vfpv4-toolchain-nodistro.0.sh

Choose the installation directory (default: /opt/dhlinux/nodistro.0/).

The toolchain is now installed to your system.

Configure Qt Creator

Run QT Creator

In Qt Creator go to Tools > Options > Devices and add your Wandboard as a generic linux device.

go to Tools > Options > Build & Run and:

Add a new c++ compiler. Select your compiler: /opt/dhlinux/nodistro.0/sysroots/x86_64-oesdk-linux/usr/bin/arm-dhlinux-linux-gnueabi/arm-dhlinux-linux-gnueabi-g++

Add a new debugger. Select your debugger: /opt/dhlinux/nodistro.0/sysroots/x86_64-oesdk-linux/usr/bin/arm-dhlinux-linux-gnueabi/arm-dhlinux-linux-gnueabi-gdb

Add your Qt version by selecting the qmake located in /opt/dhlinux/nodistro.0/sysroots/x86_64-oesdk-linux/usr/bin/qmake

Add a new kit selecting your new Qt5 version and compiler and setting the sysroot to /opt/dhlinux/nodistro.0/sysroots/cortexa7t2hf-neon-vfpv4-dhlinux-linux-gnueabi and leave the Qt mkspec empty. Then select your device

As the final point you have to set the environment of the kit: Select "Change" at "Environment:". Now a window for editing text opens. Copy all environment variables (all lines with "export"-statement) from the environment setup script /opt/dhlinux/nodistro.0/environment-setup-cortexa7t2hf-neon-vfpv4-dhlinux-linux-gnueabi and its imported files (at the end of the script) into the window. Each line should contain one environment variable assignment and "export" has to be removed.

Examlpe for setting the environment variables

/opt/dhlinux/nodistro.0/environment-setup-cortexa7t2hf-neon-vfpv4-dhlinux-linux-gnueabi also includes the files /opt/dhlinux/nodistro.0/sysroots/x86_64-oesdk-linux/environment-setup.d/cmake.sh , /opt/dhlinux/nodistro.0/sysroots/x86_64-oesdk-linux/environment-setup.d/openssl.sh and /opt/dhlinux/nodistro.0/sysroots/x86_64-oesdk-linux/environment-setup.d/qt5.sh . The files have the following content:
