ARM Development Studio 2025.0

ARM has released the latest update to Arm Development Studio, version 2025.0. This is the first publicly available release to include Arm Toolchain for Embedded Professional, and to support the latest Arm Cortex-A320 processor.

Other individual components of Development Studio have been updated to the following versions:

- Arm Compiler for Embedded 6.24
- Arm Debugger 6.6.0
- Arm Streamline 9.6.1
- Fixed Virtual Platforms (FVPs) are now based on Arm Fast Models 11.29


Arm Toolchain for Embedded Professional (ATfEP) is the next-generation Arm embedded compilation toolchain. ATfEP is almost completely open source, using technology from LLVM (assembler, compiler, linker, C++ library, binutils) and Picolib (C library). In future we expect the C library also to be taken from LLVM. This contrasts with AC6, where some components (assembler, compiler, C++ library) use LLVM technology with some downstream patches, with the remaining components (linker, C library, minor tools) are proprietary and carry over from AC5. This change in architecture brings advantages:
- Broader compatibility with GCC, including the linker script format
- Easier access to useful LLVM functionality, for example security features or memory sanitizers
- Easier support for rich OS such as Embedded Linux
ATfEP is likely to appeal to projects that:
- Are using AArch64 or Armv8.1-M cores (this is where ATfEP performance optimization is focused)
- Need compatibility with GCC
- Want to use additional functionality from the LLVM project, that was not possible to deliver in AC6
- Need to support Embedded Linux


Arm Compiler for Embedded (AC6) has reached end of development. 6.24 is the final scheduled release, and adds full support for Armv9.6-A (replacing the beta support in the 6.23 release). Importantly, AC6 has not been retired or withdrawn, and continues to be enabled by Arm Development Studio licenses. AC6 is likely to appeal to projects that:
- Are already using AC6, and want to avoid migration to the next-generation ATfEP
- Benefit from AC6 scatter-loading to handle complex non-hosted memory layouts
- Benefit from AC6 closed-source optimizations, particularly performance or code density optimizations for Armv6-M, Armv7-M, or Armv8-M cores


Arm Development Studio provides appropriate support for the Cortex-A320 throughout the product:
- Arm Compiler for Embedded
- Arm Debugger
- Arm Streamline
- Fixed Virtual Platforms
- A collection of example projects are provided to help you get started.
