Release Notes for Arm Development Studio 2022.2


This release of Arm Development Studio contains the following changes.

Processor and Architecture Support
Support for the following processors is added:
- Cortex-A715
- Cortex-X3
Support for the following architectures and extensions is added:
- Armv8.7-A and Armv9.2-A
- Realm Management Extension (RME)
Arm Compiler for Embedded
The Arm Compiler in this release of Development Studio is updated to Arm Compiler for Embedded 6.19. For more details, see the Arm Compiler Release Notes. Arm Compiler 5 is now a legacy product and has reached the end of Mainstream Support. It is no longer provided in Development Studio. Arm Compiler 5 can still be used for existing projects and for new projects for legacy Armv4, Armv5, or Armv6 targets - you can download it from the Arm Compiler 5 Downloads page, then add it as a toolchain into Development Studio. For all other new projects, Arm strongly recommends using Arm Compiler for Embedded 6 for non-safety projects and the latest Arm Compiler for Embedded FuSa (Functional Safety) for safety projects.
Arm Debugger
The Arm Debugger includes the following new features and enhancements:
- Support for Authenticated Debug Access Control (PSA-ADAC)
- Support for CoreSight SoC-600 r5p0
- Initial support for DWARF 5 debug information (see limitations below)
- Support for systems with up to 64 hardware breakpoints and/or watchpoints (FEAT_Debugv8p9)
Arm Fixed Virtual Platforms
The Arm FVPs in this release of Development Studio are updated to a selection from Fast Models 11.19. For more details, see the Fast Models Release History.
The FVP_Base_Cortex-A715, FVP_Base_Cortex-X3 and FVP_Base_AEMvA models are added in this release.
Some Armv8 FVPs with CPU cluster configurations with a fixed number of cores are replaced by FVPs with a configurable number of cores. For example, FVP_Base_Cortex-A76x1, FVP_Base_Cortex-X1x2, FVP_Base_Neoverse-N1x4 are replaced by FVP_Base_Cortex-A76, FVP_Base_Cortex-X2, FVP_Base_Neoverse-N1 respectively. When launching the FVP, use the "NUM_CORES" parameter to specify the number of cores. The Arm DS Debugger configuration database has been updated accordingly, and existing .launch files will be migrated automatically.
For Neoverse N2 (a "Direct Connect" core), FVP_Base_Neoverse-N2 is the single-core model, and FVP_Base_Neoverse-N2x1-Neoverse-N2x1 is the dual-core model.
Arm Streamline
Arm Streamline in this release of Development Studio is updated to version 8.3.0. For more details, see the Arm Mobile Studio Release Note.
Arm Graphics Analyzer
Arm Graphics Analyzer in this release of Development Studio is version 5.12.0. For more details, see the Arm Mobile Studio Release Note.
Examples
Additions include:
- A bare-metal example demonstrating the support for the Realm Management Extension (RME) in Arm Compiler for Embedded 6, the AEMvA FVP model and the Debugger.
