Tinkerboard - QT5 Yocto (Console based - Tested on Ubuntu 16.04 64 bit PC)
This is a console based Yocto QT5 image for Tinkerboard using eglfs for rendering
Prebuilt toolchain/SDK https://drive.google.com/open?id=0B2aU6UdMlrQbRnpEMURhRW9Ebzg
Prebuilt OS image - https://drive.google.com/open?id=0B2aU6UdMlrQbQ0tTbE9VRHhDQjQ
Building a fresh Yocto image
Browse to the cloned directory, then type
$ . ./setup-environment
$ bitbake core-image-base
The build/local.conf file in this repo adds a number of QT5 libraries and applications. All the example apps can be found under /usr/share/ To run each of the example apps pass -platform eglfs as additonal argument.
EG:
$ cd /usr/share/cinematicexperience-1.0
$ ./Qt5_CinematicExperience -platform eglfs
For completeness, the instructions on building toolchain and preparing QTCreator are provided below (source)
Building tool chain
$ bitbake meta-toolchain-qt5
$ apt-get install qtcreator
$ sh -glibc-x86_64-meta-toolchain-qt5-cortexa17hf-neon-vfpv4-toolchain-2.2.1.sh
Configuring QTCreator
$ cd /opt//2.2.1
$ . ./environment-setup-cortexa17hf-neon-vfpv4-rk-linux-gnueabi
$ qtcreator
In QtCreator go to Tools > Options > Devices and add "rockchip" as a generic linux device. go to Tools > Options > Build & Run and:
- Add a new compiler. Select your compiler: /opt//2.2.1/sysroots/x86_64-rksdk-linux/usr/bin/arm-rk-linux-gnueabi/arm-rk-linux-gnueabi-g++
- Add your new cross compiled Qt version by selecting the qmake located in /opt//2.2.1/sysroots/x86_64-rksdk-linux/usr/bin/qt5
- Add a new kit selecting your new Qt5 version and compiler and setting the sysroot to /opt//2.2.1/sysroots/cortexa17hf-neon-vfpv4-rk-linux-gnueabi and set the Qt mkspec to "linux-oe-g++".
- Finally select your "rockchip" for the device.
