I used the instructions and got a working BBB with a CAP LCD7. However I needed to cut the eMMC lines to the LCD CAP (BeagleToys one), it is a A3 Ref but still did not work, but the site say is 100% BBB compatible.. ha ha . The only thing that does not work is the mouse when used with the LCD CAP, but that is not a problem to me as I used the touch screen. I made a document up with the instructions as I had to change some things to get the GUI , GDD and LCD cap working.
I also think QT creator has a bug , one has to delete the xx.user file and then setup the kit, else you cannot change the kit, it still uses the original kit. So just be sure to select the correct kit when started after the .user file was was deleted. It works great !! Building and setting up QT environment for BeagleBone There are too few information available on how to easily setup QT environment for building Beaglebone applications (command line or GUI). In this tutorial we will compile QT and setup the environment from scratch. 1. My environment - Host: Ubuntu 13.10 64bit (VB) - Target: BeagleBone Black running Angstrom - QT: 4.8.5 2. Setup Angstrom cross-compile toolchain for Linux Download : - angstrom-2011.03-x86_64-linux-armv7a-linux-gnueabi-toolchain-qte-4.6.3.tar.bz2<http://www.angstrom-distribution.org/toolchains/angstrom-2011.03-x86_64-linux-armv7a-linux-gnueabi-toolchain-qte-4.6.3.tar.bz2> for 64bit host or - angstrom-2011.03-i686-linux-armv7a-linux-gnueabi-toolchain-qte-4.6.3.tar.bz2<http://www.angstrom-distribution.org/toolchains/angstrom-2011.03-i686-linux-armv7a-linux-gnueabi-toolchain-qte-4.6.3.tar.bz2> for x86 (or download more recent version at http://www.angstrom-distribution.org/toolchains/). - https://googledrive.com/host/0B3Z340LOBulvMG5NRmNlZEppSEE Run $> tar -C / -xjf angstrom-2011.03-i686-linux-armv7a-linux-gnueabi-toolchain-qte-4.6.3.tar.bz2 3. Download and un-tar QT > wget http://download.qt-project.org/official_releases/qt/4.8/4.8.5/qt-everywhere-opensource-src-4.8.5.tar.gz > tar -xzf qt-everywhere-opensource-src-4.8.5.tar.gz > mv qt-everywhere-opensource-src-4.8.5 qt-4.8.5-beagle 4. Create qmake.conf > cd qt-4.8.5-beagle > mkdir ./mkspecs/qws/linux-am335x-g++ > cp ./mkspecs/qws/linux-arm-g++/qplatformdefs.h ./mkspecs/qws/linux-am335x-g++ > touch ./mkspecs/qws/linux-am335x-g++/qmake.conf Add the following to qmake.conf with your favorite editor: # # qmake configuration for building with arm-linux-g++ # include(../../common/linux.conf) include(../../common/gcc-base-unix.conf) include(../../common/g++-unix.conf) include(../../common/qws.conf) # modifications to g++.conf #Toolchain #Compiler Flags to take advantage of the ARM architecture QMAKE_CFLAGS_RELEASE = -O3 -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp QMAKE_CXXFLAGS_RELEASE = -O3 -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp QMAKE_CC = /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/bin/gcc QMAKE_CXX = /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/bin/g++ QMAKE_LINK = /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/bin/g++ QMAKE_LINK_SHLIB = /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/bin/g++ # modifications to linux.conf QMAKE_AR = /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/bin/ar cqs QMAKE_OBJCOPY = /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/bin/objcopy QMAKE_STRIP = /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi/bin/strip load(qt_config) 5.

Build and install > make -j 4 > sudo make install 7. Install Qt SDK (lib) we built previously on your board Make sure you beaglebone is connected to your host (assume ip =192.168.7.2 USB) - ssh to your beaglebone (ssh [email protected]) - Create dir structure from your prefix: > root@beaglebone:/# mkdir /opt > root@beaglebone:/# mkdir /opt/qt > opkg install tslib-calibrate > ts-all > ts-calibrate (calibrate all points) > update-rc.d -f gdm remove > systemctl disable gdm.service > reboot - Copy lib from your host to beagle (after reboot): > scp -r /opt/qt/lib [email protected]:"/opt/qt" - Add the lib directory to path by editing /etc/profile and adding: PATH="...:/opt/qt/lib" - NS run applications preceding with - export QWS_MOUSE_PROTO=LinuxInput:/dev/input/eventx Note x could be 0 or 1 depending on your setup AND - ./xxxxx -qws where xxxx is your application 8. Download, install and configure QT Creator I suggest installing QT Creator using regular installer: Download - qt-creator-linux-x86-opensource-2.8.0.run<http://download.qt-project.org/official_releases/qtcreator/2.8/2.8.0/qt-creator-linux-x86-opensource-2.8.0.run> for x86 or - qt-creator-linux-x86_64-opensource-2.8.0.run<http://download.qt-project.org/official_releases/qtcreator/2.8/2.8.0/qt-creator-linux-x86_64-opensource-2.8.0.run> for 64bit > chmod +x qt-creator-linux-x86_64-opensource-2.8.0.run /qt-creator-linux-x86_64-opensource-2.8.0.run - Follow installation Wizard - Run Angstrom toolchain environment setup: > . /usr/local/angstrom/arm/environment-setup Test with > qmake2 and see if it response without error(not existing) Open Qt Creator and - Configure *Qt version * 1.

Go to Tools->Options->Build & Run->Compilers and click Add->GCC 2. Select compiler path: /usr/local/angstrom/arm/bin/arm-angstrom-linux-gnueabi-g++ 3.Click Ok - Configure* Kit * 1. Go to Tools->Options->Build & Run->Kits and click Add 2. Call new kit Beaglebone 3. Select device type: “Generic Linux Device” 4. Select the device you previously created 5. Select compiler you created 6. Select Qt version you created - Select GDK path as /usr/local/angstrom/arm/bin/arm-angstrom-linux-gnueabi-gdk 1. Click Ok (not found !! ) - Configure GDB 1 Goto Tools > Options > Build & Run, 2. set Debugger > Edit to /usr/local/angstrom/arm/bin/arm-angstrom-linux-gnueabi-gdb 9. Build Qt application - Create new project (File->New project->Qt Project->Qt Console application) - Edit your project (.pro) file - Add the following after “TARGET=…” line: target.files = <YOUR EXECUTABLE NAME> target.path = /home/root INSTALLS = target - Go to Projects -> Run, you should see on “Files to deploy” table your “target” settings - Now you are ready to build and deploy you project on your target board - The following example application should print Hello world inside your console: #include <QCoreApplication> #include <iostream> int main(int argc, char *argv[]) { QCoreApplication a(argc, argv); std::cout << "hello world" << std::endl; return a.exec(); } -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
