Objectives

  • Understand the ARM v8-M architecture and its security features
  • Learn about ARMv8-M Memory Protection mechanism enhancement
  • Configuring the Security Attribution unit
  • How to manage Security access faults
  • How to build and debug a secure and non-secure software
  • Students will be given access to a shared filesystem to save and share their work.
  • PDF course material
  • The labs will use a ARM Cortex-M33 based board
  • Programming skills: Some programming experience, particularly in C
  • Basic knowledge of ARM Cortex-M implementations
  • Basic understanding of Security Algorithms and Secure coding
  • Any embedded systems engineer or technician with the above prerequisites.
  • Prerequisites are checked before the training.
