For example, Yocto 2.4 Rocko was released in October 2017. Yocto versions are tied to certain versions of Linux distros.

We install Docker as described in the post Using Docker Containers for Yocto Builds. Once we downloaded all sources, we can work without an Internet connection and share the sources between builds. With a bandwidth of 50 Mb per second, downloading may take longer than building the example image. The first build downloads gigabytes of sources for hundreds of packages. The build of the example Linux image, for example, takes 53 GB disk space.Ī very fast Internet connection is a big advantage.

It has a minimum of 16 GB RAM and 100 GB free disk space.

The PC runs a Ubuntu LTS version (16.04 or newer) natively and is powered by at least an Intel Core i7 with four cores and hyper-threading. We need a powerful PC for building Linux images with Yocto. Despite its simplicity, the application requires the Qt modules Qml, Multimedia, Gui, Network and Core, GStreamer 1.x and the platform plugin eglfs, which is a simple, OpenGL accelerated windowing system. This QML application is very simple: it can only play a single, hard-wired station. When we power on the embedded device, it starts an Internet radio application – called Cuteradio.

Have fun deploying your awesome modules remotely to a Raspberry Pi.In Part 1 of the series on Qt Embedded Systems, we build a custom Linux image with Yocto for the Raspberry Pi 3B. To automatically start the runtime, change the Run configuration to "Custom Executable (on Raspberry Pi) with dv-runtime as executable and -i 0.0.0.0 as command line argument (which enables remote GUI access). This will cause the current dv-runtime instance to orderly finish running so you can restart it with the next command. The "Deployment" section should look similar to this:Īdditionally, replace the "Kill current application instance" with "Run custom remote command" containing the following line: dv-control -s put /system/ running false
Verify that the deploy paths are correct under Projects (Sidebar) → Build & Run → Raspberry Pi → Run. Select the Raspberry Pi Kit and an according build directory, e.g. the example module from (link to example module). Open the module you want to deploy as a project in QtCreator, e.g. You can ssh into the Raspberry Pi and (with a running dv-runtime) use dv-control to include the path: OLDPATH= $( dv- control - s get / system / modules / modulesSearchPath | cut - c 6-)ĭv-control -s put /system/modules/ modulesSearchPath "$OLDPATH|/home/pi/modules" An example file could look like this:ĭo not forget to also add this path to the dv-runtime config on the Raspberry Pi. You can tell it to copy other files too, but in this case we just need the the module library. The overall result should look similar to this:įollowing this tutorial, we add a file named "QtCreatorDeployment.txt" to the module directory we want to deploy in order to tell QtCreator where to copy the created module library onto the device, e.g. Finally, change Cmake Configuration to only contain the following line:.Select the just added compilers for C and C++ and select None for Debugger and Qt version.Set Sysroot to the file containing the Pi's /usr and /lib, e.g.Select "Generic Linux Device" as Device type and select the previously added "Raspberry Pi" as Device.Next add a new kit under Tools → Options → Kits, named e.g. The result should look something like this: Go to Tools → Options → Kits → Compilers and add the compilers for C and C++ (arm-linux-gnueabihf-gcc-8 and arm-linux-gnueabihf-g++-8, respectively). The final result under Tools → Options → Devices should look similar to this:Īdd the cross compilers to Qt. Follow the steps from here to add it as an Embedded Linux Device. Rsync can be used for that ( replace with the correct IP address): rsync -rl -delete-after -safe-links ADDRESS] :/ )Ĭonnect the Raspberry Pi with QtCreator. Create a file for the Pi root file system, e.g.: mkdir ~/ pi/Ĭopy the /usr and /lib directories from the Pi into it. Install the C and C++ cross compilers: sudo apt- get install gcc- 8- arm-linux-gnueabihf g++- 8- arm-linux-gnueabihfĪpart from the C and C++ compilers the /usr and /lib directories from the Raspberry Pi are required, as well as a cmake toolchain file. On your computer, open the file /etc/ssh/ssh_config and comment out the line SendEnv LANG LC_*.Ĭreate a module you want to deploy to the Raspberry Pi, e.g. Install dv-runtime-dev on the Raspberry Pi. We will be using QtCreator 4.9 on Ubuntu 19.04 and a Raspberry Pi 3 running Raspbian Buster. Developing Dynamic Vision modules for embedded systems and remote deployment has never been so much fun.įollow these steps to easily set-up the toolchain for cross-compilation and deployment with your favorite IDE QtCreator.
