Device support
Example projects
Over 9500 example projects for various evaluation boards are included in the product installation. See the Information Center.
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 requires a license renewal. This can be performed by starting the IAR License Manager and selecting License→Check for License Renewal, or by using the Light License Manager with the command
LightLicenseManager renew YOUR_PROD.EW. -
Microsoft SCC interface no longer supported
Microsoft SCC-compatible version control systems are no longer supported by IAR Embedded Workbench.
- 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\<user name>\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.
- Windows 7 deprecation warning
The Windows 7 support will be removed in the next major release EWARM 9.40.
- Network licenses
For network licenses, IAR Embedded Workbench for Arm version 9.20.1 and later require IAR License Server Tools version 2.18.2 or later. For more information, see technical note TN21842. The latest IAR License Server Tools are backward compatible with previous IAR Embedded Workbench versions.
Note: If you are running older versions of the product, the number of users displayed in the Network Licenses window might be too large. This is cosmetic and does not affect the use of your network license. The problem has been corrected in v2.17.2 of the IAR License Server Tools and the IAR License Manager.
- Mobile licenses
If you will be using a mobile license, you need to select the option to install dongle drivers during installation. The latest dongle drivers are also available in the product installation under <installation directory>\common\drivers\dongle.
- Access to Device memory
There are a number of restrictions regarding access to Device memory. This can be important if your target system boots into a state where the MMU is disabled, because then all accesses are treated as Device.
See the Arm architecture reference manuals for detailed information.
Restrictions for Device memory in AArch64 are, for example:
- Unaligned accesses to regions marked as Device always fault.
- If a multiple-register load/store instruction is interrupted, it can result in repeated accesses.
- Prefetch instructions to Device memory are not allowed.
Note that for normal C/C++ functions, LDP and STP are used to set up and tear down the stack frame, so if a function is interrupted when the stack is in Device memory, this can lead to unexpected behavior.
The compiler option --no_unaligned_access can be used to avoid unaligned accesses to Device memory.
For AArch64 this means that:
- startup code must be built with --no_unaligned_access
- the MMU must be active and the stack must be in Normal memory before interrupts are activated.
See also Arm Application Note 527, Bare-metal Boot Code for ARMv8-A Processors.
- Object format
The object format used in the compiler, assembler, linker, and debugger is based on the ARM ABI standard version 2.10 with ELF/DWARF 4.
