Keil MDK-ARM 5.31 with DFP (build 20202508)

The Keil development team is pleased to announce the availability of Keil MDK-ARM 5.31 is the most comprehensive software development solution for Arm-based microcontrollers and includes all components that you need to create, build, and debug embedded applications.

MDK Version 5.31 is mostly a bug fix release for MDK 5.30. It also improves editing experience in multi-project workspaces and features an enhanced version of the source browser.

What's new in MDK 5.31 - Release Date: 2nd July, 2020

µVision

Improved editing experience in multi-project workspaces:
- Files open in the editor but not belonging to the active project are marked with a special icon
- Dynamic syntax checking and source browsing are disabled for files that are not part of the active project to avoid conflicts.
Added M-Profile Vector Extension window:


- Arm Compiler 6 is now the default compiler for all Arm Cortex-M based devices when starting a new project. For Armv6-M and Arvm7-M devices, Arm Compiler 5 can be selected.
- MDK-Essential and MDK-Lite additionally support secure and non-secure programming for Armv8-M.
- Introduced support for CPRJ and layers for continuous integration (CI) workflows using CMSIS-Build.
- Improved FreeRTOS debugging: thread collection and stack unwinding.
- Added support for the unprivileged debug extension (UDE)
- Event Statistics: fixed a bug in thread events timing
- Code Coverage now available with FVP simulation models

Various new features and updates are available for ULINK and CMSIS-DAP debug adapters. Fixed Virtual Platforms (Fast Models) have been updated to version 11.10.22.



MDK helps you to create embedded applications for ARM Cortex-M processor-based devices. MDK is a powerful, yet easy to learn and use development system. It consists of MDK-Core and software packs, which can be downloaded and installed based on the requirements of your application.

The MDK Tools include all the components that you need to create, build, and debug an embedded application for ARM based microcontroller devices. MDK-Core consists of the genuine Keil µVision IDE and debugger with leading support for Cortex-M processor-based microcontroller devices including the new ARMv8-M architecture. DS-MDK contains the Eclipse-based DS-5 IDE and debugger and offers multi-processor support for devices based on 32-bit Cortex-A processors or hybrid systems with 32-bit Cortex-A and Cortex-M processors. MDK includes two ARM C/C++ Compilers with assembler, linker, and highly optimize run-time libraries tailored for optimum code size and performance:

ARM Compiler version 5 is the reference C/C++ compiler available with a TÜV certified qualification kit for safety applications, as well as long-term support and maintenance.

ARM Compiler version 6 is based on the innovative LLVM technology and supports the latest C language standards including C++11 and C++14. It offers the smallest size and highest performance for Cortex-M targets.

Software packs contain device support, CMSIS libraries, middleware, board support, code templates, and example projects. They may be added any time to MDK-Core or DS-MDK, making new device support and middleware updates independent from the toolchain. The IDE manages the provided software components that are available for the application as building blocks.

You will learn how easy it is to get started with MDK Version 5 to efficiently develop embedded applications for microcontrollers based on ARM Cortex-M processors series.


Keil was founded in 1985 to market add-on products for the development tools provided by many of the silicon vendors. It soon became evident that there was a void in the marketplace that must be filled by quality software development tools. It was then that Keil implemented the first C compiler designed from the ground-up specifically for the 8051 microcontroller.

In October 2005, Keil (Keil Elektronik GmbH in Munich, Germany, and Keil Software, Inc. in Richardson, Texas) was acquired by ARM.

The Keil products from ARM include C/C++ compilers, debuggers, integrated development and simulation environments, RTOS and middleware libraries, and evaluation boards for ARM, Cortex-M, Cortex-R4, 8051, C166, and 251 processor families. Since the acquisition, ARM has continued the development and support of Keil products for existing 8051, 251, and C166 markets.
