What's New in MDKARM Version 5.38

MDK-ARM Version 5.38

Release Date: 21st November, 2022

• [Consideration prior to installation]
  • By default the Destination Folder for the Core product is specified as 'C:/Keil_v5/' by the installer. In this filesystem location all local users have full access permissions. For enhanced security, users may choose to install the product into their %LOCALAPPDATA% folder (C:/Users/<user>/AppData/Local/Keil_v5/) where access is restricted to the current local user and users with administration permissions. Note that 'Show hidden files' needs to be enabled for browsing to the %LOCALAPPDATA% folder.
• [µVision updated to V5.38.0.0]
  • CMSIS-Pack configuration files:
    • Version lifecycle management enhanced: a three-way merge of the "base", the "update" and the user managed file is now possible.
    • Base version files (<configfilename&gt.<extension>.base@version) are read-only and shall be stored and shipped as part of the project. They are the unmodified default configuration file shipped with the software component. In the future, version information of configuration files will no longer be stored as part of the µVision project files (*.uvprojx).
  • Import and export of 'cprj' project files improved and updated to support recent changes in Open-CMSIS-Pack project's CMSIS-Toolbox implementation.
• [Arm Compiler included]
  • Arm Compiler 6 version 6.19 - see Release Notes for further details.
    • Note: armasm: Deprecated legacy assembler for armasm-syntax assembly code with support for older Arm architectures only. Use the armclang integrated assembler (GNU arm assembler syntax) for all new assembly files.
  • Arm Compiler 5 IS NO LONGER INCLUDED in the MDK-Core Installer.
    • Arm Compiler 5 is still supported by µVision and can be downloaded from here selecting e.g r5p6-07rel0 from the Revision drop down list to download 'Arm Compiler 5.06 update 7 (build 960) Win32'. This article explains how to configure the Arm Compiler 5 in uVision after you have installed it inside your MDK installation directory (default: c:\Keil_v5\ARM\ARMCC).
• [Software Packs included]
  • Keil - MDK-Middleware 7.16.0
    • Network Component Version 7.18.0
    • FileSystem Component Version 6.15.3

  • Keil - MDK-Middleware Graphics 1.1.0 (Unchanged from MDK 5.37)
    • Segger emWin Version 6.24.
  • Arm - CMSIS 5.9.0 (Unchanged from MDK 5.37)
    • For a comprehensive list of changes refer to CMSIS 5.9.0 Release.
  • Arm - CMSIS-DSP 1.14.2 (New)
    • The CMSIS-DSP library is now hosted on GitHub in a separate repository from CMSIS_5 and distributed in the ARM.CMSIS-DSP pack.
      All future development is done in this new repository.
    • For a comprehensive list of changes refer to CMSIS-DSP 1.14.2 Release.
  • Arm - CMSIS-NN 4.0.0 (New)
    • The CMSIS-NN library is now hosted on GitHub in a separate repository from CMSIS_5 and distributed in the ARM.CMSIS-NN pack.
      All future development is done in this new repository.
    • Backward incompatible change of return type: The return type of all API's that returned a status was changed.
      CMSIS-NN previously used error codes from CMSIS-DSP of type enum 'arm_status'. This is now replaced by enum 'arm_cmsis_nn_status'.
      The status' numeric values remain unchanged. It is recomended that users update the return type in their applications.
    • For a comprehensive list of changes refer to CMSIS-NN 4.0.0 Release.
  • Arm - CMSIS-Driver 2.7.2
    • For a comprehensive list of changes refer to CMSIS-Driver 2.7.2 Release.

• [CMSIS-Toolbox]
  • Added: CMSIS-Toolbox Version 1.3.0 including compiler configuration file for Arm Compiler 6.19 located in the c:\Keil_v5\ARM\ctools directory.
  • Follow the setup instructions for Windows to use the compiler and packs from MDK also with the commandline tools from cmsis-toolbox.
  • uVision supports the import/export of the 'cprj' project description format specified by the Open-CMSIS-Pack project.
• [Cortex-M models]
  • Arm Virtual Hardware (AVH) models were updated to Version 11.19.23.
