What's New in MDKARM Version 5.30

MDK-ARM - Version 5.30 release

Release Date: 4th May, 2020

• [uVision updated to V5.30.0.0]
  • Added support for Arm Cortex-M55 based devices.
  • Added M-Profile Vector Extension debug dialog for configurable data vector display.
  • Updated the product editions MDK-Lite and MDK-Essential to support secure/non-secure build and debug of Armv8-M and Armv8.1-M compliant processor based devices.
  • Added debug functions for conversions between raw integer and floating point values: F32ToRawF16, F32ToRawF32, F64ToRawF64, RawF16ToF32, RawF32ToF32, and RawF64ToF64.
  • Arm Compiler 6 gets selected by default when creating a New Project for Arm Cortex-M based devices.
