Highlights

Version 7.40.6 Functional Safety

• This is a functional safety version of IAR Embedded Workbench for ARM. Links to Functional Safety specific information:

  • IAR Embedded Workbench Safety Guide
  • Statement from Dinkumware, Ltd. for Standard C and C++ library

Version 7.40.3

• I-jet Trace 1- and 2-bit support
  I-jet Trace can now collect ETM trace data with 1 and 2-bit wide trace buses. Note that the I-jet Trace firmware must be upgraded to revision 5.4 to activate this feature.

• Enhanced support for TI XDS debug probes
  It is now possible to use data breakpoints, SWO trace, and vector catch when using an XDS probe in combination with a Cortex-M device in C-SPY. The configuration possibilities are also improved in the project options. The level of support for the new features depends on which XDS probe you are using and the features it provides.

Version 7.40.1

• C-STAT
  The add-on product C-STAT for static analysis is now supported. C-STAT features innovative static analysis that can detect defects, bugs, and security vulnerabilities as defined by CERT and the Common Weakness Enumeration, as well as help keeping code compliant to coding standards like MISRA C:2012/2004 or MISRA C++:2008. For more information, see C-STAT Static Analysis Guide.

• Parallel build
  The compiler can now run in several parallel processes to better use the available processor cores in the PC. To control parallel build, choose Tools>Options>Project>Enable parallel build.

• Cortex-M7 devices
  Device support for Cortex-M7 devices from Atmel (ATSAMx7) and ST (STM32F756), including support for the double precision floating point unit.

Important information

• Upgrade information
• Before you install
  

  To avoid any problems, do not install this release in a directory where you have previously installed any older version of IAR Embedded Workbench. It is recommended that you either uninstall an earlier product, or install this release in a separate directory. As before, however, it is possible to install different products, all using the same version of the main application, in the same root directory.

• License renewal
  

  The upgrade to this version might require a license renewal. This is performed by starting the IAR License Manager and selecting License>Check for License Renewal.
  Note, if you have a network license, this must be performed on the license server.

• Microsoft Windows
  

  Windows Vista and newer operating systems have a security mechanism called UAC (User Access Control). Disabling UAC will automatically grant you permission when a task requires administrative rights but this is not recommended because it will reduce the security of the computer. It is not necessary to run the IAR Embedded Workbench IDE as an administrator. However, if you are not, modifications to the installed product tree in C:\Program Files\IAR Systems might not work as intended and could give unexpected results. One example is opening and building projects directly from the installed product tree. The build will succeed, but the resulting files (object, list, ...) will not appear where expected. Instead all output files will be redirected by the OS to C:\Users\\AppData\Local\VirtualStore\Program Files\IAR Systems. To avoid this, the preferred way is to copy the examples to a location outside Program Files, either manually or automatically by opening them via the IAR Information Center.

• Migration

• The debugger flash loader mechanism was changed in version 5.40. If your project uses a default flash loader with no extra parameters, no migration work is needed.
  If the debugger detects that your project uses a non-default flash loader or that it uses extra parameters, it will revert to the default flash loader for your device. In addition a .board file will be created in the project directory. If necessary the .board file can be edited and used by manually overriding the default flash loader with this project-specific .board file.

• If you are migrating from version 4.x to this version, we recommend that you read the ARM IAR Embedded Workbench Migration Guide.

• Object format
  

  The compiler, assembler, linker and debugger object format is based on the ARM ABI ELF/DWARF standard version 2.08. For the standard definition, see the ARM Application Binary Interface.
