[FAQ] TI-RTOS: I have installed SimpleLink SDK and I can't use ROV in the IAR EW

I have installed SimpleLink SDK 3.30 (or any other SDK version that requires the IAR EW for Arm 8.32) and now I see the warning “SYS/BIOS ROV session manager failed - can't find a JVM” whenever I start the debugger. I also don't have the menu TI-RTOS in the debugger menu bar. What does the warning mean and how can I fix it?

  • The ROV tool for IAR requires an update to work properly. If you are an ROV user, follow the instructions below. If you don’t use ROV, you can proceed with the standard debugging sessions, the ROV tool does not affect any other debugger functionality.


    A new version of the IAR ROV tool is available in the SimpleLink SDK version 3.30. Please follow these steps to install an update:


    1. Close the IAR EW if currently opened.

    2. Go to the directory <IAR_EW_install_path>/arm/plugins/rtos/TI-RTOS and rename the existing version of the file tirtosplugin.dll. Keep the renamed file available, in the case that the file update has to be reverted.

    3. Go to the directory <SDK_install_path>/tools/iar/ and select the file tirtosplugin.dll.

    4. Copy tirtosplugin.dll to the directory <IAR_EW_install_path>/arm/plugins/rtos/TI-RTOS.


    Note: Some Windows installation may require Administrator privileges to rename a file or copy a file into the IAR EW installation directory.
