IAR Embedded Workbench for Arm 6.10: A Powerful Development Toolchain for Embedded Applications

IAR Embedded Workbench for Arm is a set of highly sophisticated and easy-to-use development tools for embedded applications. It integrates the IAR C/C++ Compiler, assembler, linker, librarian, text editor, project manager, and C-SPY Debugger in an integrated development environment (IDE). With its built-in chip-specific code optimizer, it generates fast, compact, and energy-efficient code for a wide range of Arm devices.

In this article, we will review some of the features and benefits of using IAR Embedded Workbench for Arm 6.10, which was released in June 2012. We will also provide some examples of how to use the toolchain to develop and debug embedded applications based on Arm cores.

Features and Benefits of IAR Embedded Workbench for Arm 6.10

IAR Embedded Workbench for Arm 6.10 offers many features and benefits that make it a powerful and reliable toolchain for embedded development. Some of these features and benefits are:

• Support for over 7,000 Arm devices, including all 32-bit Arm cores from all major vendors and selected 64-bit Arm cores, such as Cortex-M0, Cortex-M0+, Cortex-M1, Cortex-M3, Cortex-M4, Cortex-M7, Cortex-R4, Cortex-R5, Cortex-R7, Cortex-R8, Cortex-A5, Cortex-A7, Cortex-A8, Cortex-A9, Cortex-A15, Cortex-A17, Arm11, Arm9, Arm7 and SecurCore .

• Leading compiler technology that offers advanced global and target-specific optimizations, such as loop unrolling, function inlining, dead code elimination, constant propagation, tail recursion elimination, instruction scheduling and more. The compiler also supports C and C++, as well as various industry-standard debug and image formats.

• Comprehensive debugger that provides an Arm instruction simulator and extensive support for debugging probes and target systems. The debugger also supports complex code and data breakpoints, runtime stack analysis, call stack visualization, code coverage analysis, power consumption monitoring and more. In addition, the debugger offers multicore debugging with support for symmetric multicore processing (SMP) and asymmetric multicore processing (AMP).

• Integrated code analysis add-ons that help to ensure code quality throughout the development and testing process. The static analysis add-on C-STAT checks compliance with coding standards such as MISRA C:2004, MISRA C++:2008 and MISRA C:2012. The runtime analysis add-on C-RUN performs bounds checking, arithmetic checking and heap checking.

• User-friendly IDE that provides project management tools and editor with features such as auto-completion, code folding, syntax highlighting and more. The IDE also includes over 8,400 example projects containing configuration files, code examples and project templates.

• Flexible licensing options that suit different organizational needs. The toolchain can be licensed as a node-locked license or a floating license. The node-locked license allows one user to use the toolchain on one computer. The floating license allows multiple users to share the toolchain on a network.

• Global support and continuous product updates that ensure the toolchain is always up to date with the latest technology trends and device support. The toolchain comes with a Support and Update Agreement (SUA) that gives access to technical support services and product updates.

Examples of Using IAR Embedded Workbench for Arm 6.10

To illustrate how to use IAR Embedded Workbench for Arm 6.10 to develop and debug embedded applications based on Arm cores, we will use two examples: a blinky LED project based on the STM32F4 Discovery board with a Cortex-M4 core; and a hello world project based on the Raspberry Pi board with a Cortex-A7 core.
