Host Computer Requirements


DS-5 requires a minimum specification of computer with a dual core 2GHz processor (or equivalent) and 4GB of RAM. A full installation requires approximately 4GB of hard disk space. A minimum screen resolution of 1024x768 is required.
DS-5 is supported on the following host platforms and service packs:


In addition, ARM Compiler toolchains are supported on the following host platforms:


Debug System Requirements


Linux application debug requires gdbserver on your target. The recommended version of gdbserver is 7.0 or later. DS-5 Debugger is unable to provide reliable multi-threaded debug support with gdbserver versions prior to 6.8.
Linux application rewind requires undodb-server on your target. DS-5 Debugger copies undodb-server to the target for you in the Download and Debug connection type, but for all other connection types, you must copy it yourself. The undodb-server binary is located in arm\undodb\linux under the DS-5 installation directory. Application rewind does not follow forked processes. When debugging backwards, you can only view the contents of recorded memory, registers, or variables. You cannot edit or change them.
DS-5 support for Linux application debug depends on infrastructure and features that are introduced in specific kernel versions:


ARM Linux kernel and bare-metal debugging require the use of additional tools (not supplied with DS-5) to connect to your target system. DSTREAM, DSTREAM-ST, RVI, ULINKpro and ULINKpro D debug units allow connection to physical hardware targets. VSTREAM allows connection to RTL simulators and hardware emulators.
The minimum supported firmware version for DSTREAM, DSTREAM-ST, RVI and VSTREAM is 4.31.0. For DSTREAM, DSTREAM-ST and RVI it is recommended that you use the supplied debug hardware update tool to check that you are using the latest firmware and to update it if necessary. Updated firmware is available in the /sw/debughw/firmware directory. The firmware for VSTREAM is delivered as part of the VSTREAM software, so you must obtain and install a newer version of this product if the firmware version is too old.
DSTREAM-ST uses Ethernet over USB to connect to your computer. DSTREAM-ST should automatically be detected as a network device and be visible as a network adapter in the Device Manager on Windows, or listed as a USB network interface by the ifconfig utility on Linux. If this is not the case then you may have to perform some configuration on your computer - please refer to the DSTREAM-ST troubleshooting section at: https://developer.arm.com/products/software-development-tools/debug-probes-and-adapters/dstream-st/troubleshooting-your-dstream-st-unit.

Install on Linux


To install DS-5 on Linux, run (not source) install.sh and follow the on-screen instructions. The installer unpacks DS-5 into your chosen directory, adds desktop shortcuts, and optionally installs support for hardware debug units.
Some of the tools installed have dependencies on 32-bit system libraries. You must ensure that 32-bit compatibility libraries are installed when using DS-5 on 64-bit Linux host platforms. DS-5 tools might fail to run or report errors about missing libraries if 32-bit compatibility libraries are not installed. The ARM Knowledgebase contains further information about the required DS-5 dependencies: http://infocenter.arm.com/help/topic/com.arm.doc.faqs/ka14522.html.
The installer includes configuration files to allow USB connection to DSTREAM, DSTREAM-ST, RVI, ULINKpro and ULINKpro D hardware debug units. It is recommended to install these files if you intend to use these features. Installation of these files requires that you run the installer with root privileges. If you do not run the installer with root privileges or choose not to install these files, then you can still install them after installation by running the /run_post_install_for_ARM_DS-5_v5.27.0.sh script with root privileges. The installer creates a desktop menu using the freedesktop.org menu system on supported Linux platforms.

Install on Windows


To install DS-5 on Windows, run setup.exe and follow the on-screen instructions. If you have an earlier version of DS-5 already installed, this one will be installed alongside, without uninstalling your previous installation.
During installation you might be prompted to install device drivers. These drivers are to allow USB connections to DSTREAM, DSTREAM-ST, RVI, ULINKpro, ULINKpro D and Energy Probe hardware units. It is recommended to install these drivers if you intend to use these features.
Command-line installation and uninstallation are possible on Windows by opening a command prompt, with administrative privileges, and running Microsoft's installer, msiexec.exe. You must provide the location of the .msi file as an argument to msiexec. You can get a full list of options for using msiexec by running msiexec /? on the command-line. An example of how to install DS-5 using msiexec is:
msiexec.exe /i \data\install.msi EULA=1 /qn /l*v install.log
Where:



After Install


After installation, you can start Eclipse for DS-5 from the ARM DS-5 v5.27.0 -> Eclipse for DS-5 v5.27.0 entry in your desktop menu. Be aware that any existing "Eclipse for DS-5" entry in the desktop menu will point to the previous version of DS-5 that is still available for use on your host. Eclipse for DS-5 and other supplied tools can also be found within the /bin directory.
Portions of DS-5 are license managed and you must install a license before using them. See the Obtaining and Installing Your License section of these release notes below for further information about this.
The installer does not modify any environment variables on your system. To run the tools more easily from a console you can manually add the /bin directory to your PATH environment variable. You should be aware that DS-5 includes copies of gcc and make that might behave differently from any copies that are installed elsewhere on your system. For this reason, if you modify your PATH environment variable, it is recommended that you do this locally within a console rather than globally for your entire system. See your operating system documentation for further information on setting environment variables.
On Linux you can run /bin/suite_exec  to open a shell with the PATH environment variable correctly configured. Run this tool with no arguments for more help.
On Windows the Start menu contains DS-5 Command Prompt. This console is preconfigured with the bin directory added to the PATH environment variable.
On both Linux and Windows the command prompts do not provide a compiler toolchain by default, but you can select one using the select_toolchain or select_default_toolchain commands.
Further information on using DS-5 can be found in the on-line help within Eclipse for DS-5. To access the on-line help, start Eclipse for DS-5 and select Help -> Help Contents. The main documentation for DS-5 can be found under the DS-5 Documentation section in the contents.
Separate documentation is provided for the supplied Examples in the /examples/docs/index.html document, which is also linked to from the Examples Index menu entry in the ARM DS-5 v5.27.0 Windows Start menu.
You can find further instructions on installation, licensing and tutorials on-line at: https://developer.arm.com/products/software-development-tools/ds-5-development-studio/resources/tutorials/getting-started-with-ds-5-development-studio.

Obtaining and Installing Your License


You must obtain a valid license before using DS-5.
You can use the License Manager dialog in Eclipse for DS-5 to obtain and install node-locked licenses on both Windows and Linux. You can open this dialog by selecting ARM License Manager in the Eclipse for DS-5 Help menu.
Alternatively, floating and commercial (paid-for) node-locked licenses can be obtained and installed manually. Further instructions on this can be found in the ARM DS-5 License Management Guide document in the /documentsdirectory and on our website:


When the license and toolkit are configured within Eclipse then all license managed components will pick up the license and toolkit settings correctly, both within Eclipse and within the provided DS-5 Command Prompt (Windows) or suite_exec shell (Linux). If you use a different console then you must configure the tools manually. To do this, please refer to the tools documentation.
If you are using floating licenses, then the version of the FlexNet license server software must be greater or equal to the version of FlexNet used within the DS-5 tools. This release of DS-5 contains tools based on FlexNet 11.14.1.0.
Consult the License Management FAQ at http://infocenter.arm.com/help/topic/com.arm.doc.faqs/kiLwjCHu92xQmR.html for more assistance with the installation of your license.
Contact license.support@arm.com if you need additional help with registering or obtaining your license. Please provide your serial number and a detailed description of the problem.

Uninstall


To uninstall DS-5 on Windows, use Add or Remove Programs in Control Panel, select ARM DS-5 v5.27.0 and click the Remove button.
To uninstall DS-5 on Linux, run remove_menus_for_ARM_DS-5_v5.27.0.sh in the root directory of your installation to remove desktop menu entries, and then simply delete the installation directory.
On both Windows and Linux, some per-user configuration is stored outside of the installation directory, which you might optionally choose to delete. For Windows these files are stored in %APPDATA%\ARM. For Linux these files are stored in $HOME/.arm.
Known Issues and Limitations
The following known issues and limitations exist in this release:
Eclipse for DS-5


  • Problem: Eclipse fails to start and reports "cannot restore segment prot after reloc: Permission denied" [SDDEBUG-13327]

Workaround: This error occurs because some of the shared libraries used by the applications require text relocation, but the Security-enhanced Linux (SELinux) policy on your machine prohibits this. To work around this, change the SELinux policy for your DS-5 applications and shared libraries to allow text relocation. This can be achieved with the following command, run under a super user account:
chcon -R -t texrel_shlib_t ""

  • Problem: Eclipse fails to start and reports "JVM terminated" or outputs a stack backtrace. [SDDEBUG-4443]

Workaround: This problem is often caused by heap settings for Eclipse that are not suitable for the computer that you are running it on. To fix this you must edit /sw/eclipse/eclipse.ini to supply alternative heap settings. The following knowledgebase article provides detailed instructions on making this change: http://infocenter.arm.com/help/topic/com.arm.doc.faqs/ka14185.html.
