Product update: Arm Development Studio 2021.1 now available

Arm has released the latest updates to Arm Development Studio, with the 2021.1 release of the Gold, Silver, and Bronze editions, with 2021.b Platinum Edition following soon after.

The main new features are the following:

• a number of significant updates to the Arm Debugger and Streamline components of the product
• Cortex-A65, Cortex-A65AE, and Neoverse-E1 processors support in Silver and Gold editions (see all supported processors)
• the first to support the new DSTREAM-XT debug adapter

Enhanced debug over functional I/O

To meet the demands of automotive and other industry needs for enhanced test and validation capabilities on ever more complex systems, Arm has released DSTREAM-XT. It is our most capable debug adapter that supports debug and trace over PCIe to the target. This greatly increases the potential trace bandwidth, while also removing the need for dedicated debug interfaces on the SoC. The 2021.1 Arm Debugger is the first to support DSTREAM-XT. For more information, see here.

Flexible debug options

There have also been a number of stability and usability improvements to the Debugger. In addition to DSTREAM-XT, ULINK-Plus and CMSIS-DAPv2 debug adapters are now supported. You can now easily select the debug port (JTAG or SWD) and debug clock speed directly in the Debug Configurations pane.

Fixed Virtual Platforms (FVPs) of Cortex-A65, Cortex-A65AE, and Neoverse-E1, as well as example projects and debug configurations, are also provided.

The Streamline Performance Analyzer is updated to version 7.7, and Arm Graphics Analyzer 5.8 completes the suite of debugging tools.

Compiler performance and safety update

The latest Arm Compiler 6.16 is included. This was also supplied in the previous 2021.0 release, and you can read about the performance improvements implemented here. A Gold Edition license allows you to compile projects of Cortex-A65, Cortex-A65AE, and Neoverse-E1 processors. Until now, developing for these processors required a Platinum Edition license.

If you are working on a project that requires Functional Safety (FuSa) qualified tooling, please note that this compiler version is being used as the basis for the next safety qualified branch. We expect this to be available in Q3 2021, subject to the qualification schedule. Developers are suggested to start working with Arm Compiler 6.16 as is today, and easily migrate to the 6.16 LTS branch when available. For more information, see here.

Available now

Development Studio 2021.1 is available to download now. New to Development Studio? A fully-featured 30-day evaluation license is available free of charge. A Development Studio license also enables Keil MDK. The latest 5.34 release of MDK also integrates Arm Compiler 6.16. For more information on that release, see here.
