IAR Information Center for Arm

• Examples on demand
  To increase the download and installation speed for IAR Embedded Workbench, the example projects are no longer part of the installed product. Example projects can be downloaded per chip manufacturer using the Examples page in the IAR Embedded Workbench Information Center. In case no internet access is available, the examples can also be unpacked from the DVD installation media.

• Improved integration with Freescale Processor Expert
  The Project Connection mechanism used to seamlessly pass project content from Processor Expert to IAR Embedded Workbench has been extended to also transfer device name, linker control file and complete path information.

• #pragma default_variable_attributes and #pragma default_function_attributes
  Two new pragma directives have been added to set default placement and attributes for variable/function declarations and definitions.This means that you can override multiple declarations and definitions by using a single #pragma.

  The Freescale Kinetis CDC Device example was incorrectly referred to as a USB mouse example.
  [EW23691]

• In EWARM 6.50.3:
  If a Project>Project Connection command added an include path to the Additional include directories field on the Project>Options>C/C++ Compiler>Preprocessor options page, and that path contained any environment variables like $PROJ_DIR$, they were expanded and the path was saved that way. Now paths are saved unconverted.
  [EW23698]

• In EWARM 6.50.3:
  Projects with many include files and/or many #define statments could make the source browser slow. This has been corrected.

  caused a number of functions following such a definition to be omitted from the editor Go to Function window. This has been corrected.
  [EW22809]

• The following construction:

  #define INCLUDE 
  #include INCLUDE
  int main(void)
  { 
    ......
  

  could cause the source browser to miss the definition of main. This no longer happens.
  [EW22948]

• A failed post-build step was not included in the error count displayed in the status bar. This has been corrected.
  [EW23110]

• Power debugging
  Power debugging is a methodology that provides software developers with information about how the software implementation in an embedded system affects system level power consumption. By coupling source code to power consumption, testing and tuning for power optimization is enabled. The debug probe samples the momentary current drawn by the system and feeds it to the debugger where the measured current is synchronized with time stamped program counter values. This allows the debugger to present power consumption directly correlated to the source code. The debugger supports power data from the following sources:

  • J-Link Ultra
    Power data is measured with high accuracy at the board level. A future adapter will be available in Q2 2011 to measure power at the MCU level. Supports calibration.
  • J-Link
    Power data is measured with low accuracy at the board level. Does not support calibration.
  • The Energy Micro EFM32 Gecko development and starter kits
    They have a J-Link compatible debug probe integrated on-board. Power data is measured with high accuracy at the MCU level. Does not need calibration.
  Power data can be visualized as a power log, a graph on a time scale, or in the function profiler as energy consumption.
  More information can be found in IAR Embedded Workbench® C-SPY Debugging Guide

  [EW20121]

• Multi-file compilation
  It is now possible to use the IDE to define compilation units with multiple files that will be compiled as one unit, giving the compiler a larger scope for code optimizations.
• Cortex-M3 SWV/SWO
  Cortex-M3 SWV (Single Wire Viewer) trace packets sent over the Cortex-M3 SWO channel can be presented by the debugger. The user have full control over the selection of trace packet types. The communication rate is 6 MHz when using J-Link v7 or newer (500 kHz for older J-Link versions)
• Printf via SWO at the click of a button
  For Cortex-M3, printf output can be sent via the SWO channel (that is part of the SWD interface), and displayed in the debugger terminal I/O window. The advantage is real-time performance for debug log messages because the CPU does not need to be halted.
  To enable: Project Options>General Options>Library Configuration>Via SWO.
• Printf via DCC
  For ARM7 and ARM9, printf output can be sent via the DCC channel, and displayed in the debugger terminal I/O window. The advantage is real-time performance for debug log messages because the CPU does not need to be halted.
  Further information can be found here.
• Flash breakpoints
  Flash breakpoints allows an unlimited number of breakpoints to be active even when locating code in flash. Flash breakpoints is available for the J-Link probe and available as a separate product.

  Symbols from one link image can be used as input when linking another image. This is useful when an application depends on code in a resident (ROM) image. See the description of the ISymExport tool for more information.
• J-Link control panel
  When a debug session is active, the J-Link control panel can be activated using the J-Link button in the Windows notification area. The control panel gives access to J-Link setup parameters and shows J-Link status information.
• $CONFIG_NAME$
  A new argument variable $CONFIG_NAME$ has been added. It expands to the name of the current build configuration, for example Debug or Release.
• IAR proprietary variant of semihosting
  An IAR proprietary variant of semihosting can be selected that does not use the SVC instruction and thus does not need to set a breakpoint on the SVC vector. This is an advantage for applications which require the SVC vector for their own use, for example an RTOS.

• Stack window
  To monitor the memory consumption and integrity of the stack, a new Stack window has been added. It shows the stack contents as raw data, C/C++ variables, and function frames. It also shows current and maximum stack consumption graphically. Warnings can be issued when the stack exceeds a certain level or if the stack pointer points outside the stack memory.

• New breakpoint category - Log breakpoint
  Log breakpoints make it easy to log messages whenever execution passes a certain code location without having to add any code to the target application. When a log breakpoint is triggered, it writes to the Debug Log window and then the application continues execution.

• New way to toggle breakpoints
  You can now set or clear a breakpoint by double-clicking in the left margin of the editor window; the breakpoint location is marked by a red X. If there is more than one possible breakpoint location in the source line, the breakpoint is placed on the first location.
