New licensing management system (LMS) introduced

The new LMS used with this release introduces new features like commuter licenses, automatic license activation and support for virtual servers.

Sampled Graphs in C-SPY

It is now possible to specify variables for which you want to collect data samples. You can view the sampled data either in table format in the Data Sample window or as graphs in the Sampled Graphs window.

Custom SFR window

It is now possible to define custom SFR's (special function registers) in C-SPY with selectable access size and type.

Call Graph window

A new Call Graph window has been added. It is browsable and displays all calls made to and from each function from any source file in the active project.

Macro Quicklaunch window

The new Macro Quicklaunch window makes it possible to evaluate expressions and to launch C-SPY macros. The return value from the evaluated macro or expression is shown in a separate column and the user can re-trigger the evaluation at any given point.

Subversion

The version control integration has been extended with support for Subversion (SVN).

Extended functionality in C-STAT

Updated the MISRA C 2004 package with 19 new checks.

General improvements of the IDE startup time and overall performance. Further performance improvements will be implemented in the next release in Q2 2018.

Improved RTOS awareness plug-in for Amazon FreeRTOS

Now with full control of the execution at the task level and enabling display of the local execution context for each individual task.

CMSIS version 5.3 including CMSIS NN for machine learning

CMSIS version 5.3 adds the CMSIS NN software library, a collection of efficient neural network kernels developed to maximize the performance and minimize the memory footprint of neural networks on Cortex-M processor cores.

ST ST-LINK debug probe TCP support

ST-LINK debug driver support for ST-LINK Shared mode using a TCP server.

Nuvoton Nu-Link debug probe support

Nuvoton Nu-Link debug probe support is now integrated into the IAR Embedded Workbench for Arm installation.

Atollic TrueSTUDIO project converter

A project converter is now available to ease porting Atollic TrueSTUDIO projects to IAR Embedded Workbench for Arm.

Updated IAR XLINK Linker and library tools.

Initial support for the Arm v8-R architecture

This release provides basic supports for the Arm v8-R/Cortex-R52 architecture.

Stack protection

The IAR C/C++ compiler for Arm now supports stack protection. A canary value will be placed between the stack variables and the return address so that the system can detect corruption of a function return address before the function returns to that address. The compiler will use heuristic to determine whether a function needs stack protection or not. If any defined local variable has the array type or a structure type that contains a member of array type, the function will need stack protection.

Fault exception viewer

The Fault exception viewer is a new debugger window that provides useful information about the cause of a fault exception. It lists the peripheral registers in the System Control Block (SCB) that control fault exceptions and provide information of their cause. All Cortex-M processors have a fault exception mechanism included and is therefore supported by this new feature.

Updated MISRA C:2004 package in C-STAT

The MISRA C:2004 package in C-STAT has been updated with about 20 new checks, of which some are enabled by default.

Support for new devices from NXP, Realtek, ST and TI

Updated IDE

The IDE has new artwork, enhancements to window management and docking, customizable toolbars, revised Information Center, and new tutorials.

Enhanced Registers and Symbols windows in the C-SPY debugger

The C-SPY Symbols and Registers windows have been re-designed with new features. The Symbols window now has a filtering function and a new column displaying to which program module a certain symbol belongs. Some of the new features in the Registers window are drag-and-drop support from source code windows, detailed register tool-tip information, and improved handling of user-defined registers groups.

E2 emulator support

C-SPY now supports the Renesas E2 on-chip debugging emulator.

C-SPY start/stop function support

The start/stop function available for the OCD emulators makes it possible to execute specified routines of the user application immediately before starting and immediately after halting program execution.
