| embeddedlinux | Embedded Linux: building a system from the ground up | 14 hours | Embedded Linux, with its low cost, ease of customization, and compatibility with many types of microprocessors has become the natural choice for powering a wide range of devices such as smart phones, tablets, set-top boxes and MP3 players. In this training participants will learn step-by-step how to build an embedded Linux system from the ground up. From building a minimalistic kernel to configuring the bootup and initialization processes, participants will learn the tools, techniques and mindset needed to deploy a fully functional embedded Linux system. For remote trainings, QEMU will be used to emulate the hardware. Other platforms, including real hardware devices, can be considered on a case by case basis. Audience System engineers Format of the course Part lecture, part discussion, heavy emphasis on hands-on implementation Introduction Essential elements of an embedded Linux system Preparing your cross-compilation toolchain Understanding the boot process Configuring, compiling and booting the kernel Accessing your hardware using JTAG Compiling BusyBox Building and modifying a root file system Overview of available init systems Writing systemd service files Installing applications for additional functionality Setting up networking Updating the U-boot boot-loader Tools and workflows for modifying, testing and debugging your Linux embedded system Closing remarks |

| yp1 | The Yocto Project - An Overview - hands-on | 28 hours | Description This four day training combines theory with hands-on exercises in order to introduce the Yocto Project. It answers frequently asked questions like: Is it really necessary to use another version of the toolchain/libraries/packages for each and every GNU/Linux project and an top of that to follow a different work-flow? Can you ensure that the development environment is identical for all developers/suppliers and that you can still produce identical builds like today in 10+ years from now? Can the YP help find out under what software licenses the packages you use are licensed? ... and much more Hands-on sessions are performed on target hardware (e.g. Beagle Bone Black Rev. C - http://beagleboard.org/BLACK). After the training you will be able to download a docker image with Ubuntu 14.x and all dependencies pre-installed plus the examples in order to work with the course material in your own labs. Please note that this is not an introductory course to Embedded GNU/Linux. You should already know how Embedded GNU/Linux works and how to configure/build the GNU/Linux kernel and kernel drivers. Who should attend? You already use GNU/Linux for your projects and have probably heard about the Yocto Project, but did not dare to have a closer look into it, or had difficulties using it. You don’t know whether and how your daily work-flow can be accommodated in the YP and generally find the YP rather complicated. Why do we need all this since up to know everything was (supposedly) much easier? After the training you should be able to decide whether you need the YP or not. The workshop is aimed at software-, development-, system engineers, testers, administrators, engineers and other parties interested in the YP, with a solid knowledge of Embedded GNU/Linux. Delivery options All the training material is English, but the presentation of it can be in English or in German, as you wish, worldwide. on-site - instructor driven*) on-line - instructor driven**) on-site/on-line combination - instructor driven*)**) During the training we’ll provide laptops*), boards*)**), workbooks (in English)*)**), remote access to servers and boards**), screen-sharing**), audio-bridge**).

| Embedd8526 | Using C++ in Embedded Systems - Applying C++11/C++14 | 21 hours | This training intends to introduce C++ as the common extension of C when applying object-oriented embedded system development. Since C++ encloses C, this training takes us from C to C++ in a natural way, and looks under the hood of how C++ is implemented. This is especially valuable to comprehend when applying C++ in an embedded resource limited environment. The C++ standard has recently been undergoing a major revision, a.k.a. as C++11, and a new one is on its way, C++14. This course addresses subjects brought in with these revisions that are especially useful like high performance memory management, concurrency making use of a multicore environment, and bare-metal close to the hardware programming. GOAL/BENEFITS The major objective of this class is that you shall be able to use C++ in a “correct way”. Introduce C++ as an object oriented language alternative in an embedded system context Show the similarities ‑ and differences ‑ with the C language Comprehend different memory management strategies – especially the move semantics introduced with C++11 Look under the hood and understand what different paradigms in C++ leads to in machine code Use templates to achieve type safe high order abstractions for bare-metal close to the hardware programming – memory mapped I/O as well as interrupts – especially the variadic templates introduced with C++11 Provide some useful design patterns especially applicable in an embedded context A few exercises in order to practice some concepts AUDIENCE/PARTICIPANTS This training is aimed C++- programmers who intend to start using C++ in an embedded system context. PREVIOUS KNOWLEDGE The course requires basic knowledge in C++ programming, corresponding to our trainings ”C++ – Level 1” and ”C++ Level 2 – Introducing C++11”. PRACTICAL EXERCISES During the training you will practice the presented concepts in a number of exercises. We will use the open and free integrated development environment from Eclipse What’s an Embedded System? Simple Definition Some Milestones Characteristics Why using C++? Comparison with C C: A subset of C++ – almost Performance Added “Free” Functionality Why not using C++? Classes Member Variables Instance variables Class variables Member Functions Instance functions Class functions Implicit Methods Constructor Initialization Delegation Destructor Copy assignment operator Move Semantics – avoiding unnecessary deep copy struct in C++ Package/Namespace Inheritance Introduction Realization Performance Multiple Inheritance Virtual Inheritance Polymorphism Introduction Virtual Function Virtual Destructor Implementation Runtime Type Information, RTTI Performance Templates Introduction Function Template Class Template Variadic Templates Code Bloat Implementation Strategies Template Meta Programming Template versus Inheritance? Error Handling Exception Handling Performance Issues Implementation Inline Code When to Use? Strategies Start-up System Start-up The C Part The C++ Part Standard Library Standard Template Library, STL iostream Library Major extensions made on STL due to C++11: Move semantics Variadic Templates Concurrency Memory Management The C++ Memory Model The stdint-types Atomic types and their operations Strategies Variables Placement new User Defined Memory Management Interoperation between C and C++ Name Mangling Static Initialization Dynamic Memory struct Contents POD – Plain Old Data type Design Patterns RAII – Resource Acquisition Is Initialization Memory-mapped I/O Interrupt Initialization of Static Objects |
