With the ever increasing range of applications for Arm® microcontrollers, from simple environmental monitors, through to automotive components and complex consumer appliances, the issue of security when developing these devices has never been so crucial.
This course covers the security aspects of software design in Arm's latest v8-M processors (including the Cortex®-M23 and Cortex-M33) that utilize TrustZone v8-M Security Extensions. The training includes architecting the software, configuring the secure side, accessing secure APIs from the non-secure side and dealing with exceptions.
The workshops are based around carefully designed exercises investigating features of the TrustZone-M architecture and their practical application. If you have specific security application requirements, please contact the Doulos team to discuss your options.
This course is also an ideal follow-on from the Developing with Arm Cortex-M class for delegates interested in the Cortex-M23/M33/M35 & M55 security features.
Non-security topics (such as understanding the use of DSP instructions or the floating-point unit, optimization and standard debugging techniques) are covered in other courses. See Arm Cortex-M23/33 Software Design Online.
This course is aimed at electronic hardware, software and system-on-chip engineers who need to gain a working knowledge of this new security architecture. This could include:
Delegates should have good knowledge of embedded systems, and a basic understanding of embedded programming in C and assembler. Solid knowledge of the Cortex-M architecture (M0+, M3, M4 or M7) is required. Alternatively, prior attendance of Developing with Arm Cortex-M Online. Please contact Doulos directly to discuss and assess your specific experience against the pre-requisites.
Doulos training materials are renowned for being the most comprehensive and user-friendly available. Their style, content and coverage are unique in the Embedded Systems training world, and have made them sought after resources in their own right. The materials include:
The training materials for this class are based on Arm's own material and supplemented by Doulos’ own lecture modules and hands-on exercises to provide students with the most practical and thorough information to achieve a well-rounded knowledge of the subject. Doulos is a global Arm Approved Training Partner.
The tool-chain required for the exercises are provided within a self contained virtual machine. The student is only required to install the VirtualBox software on her/his Windows/Linux/Mac host machine. The remaining tools and exercises files are pre-configured and located inside the Virtual Machine to be run locally. The VM can be used for day do day embedded software development and allows the student to continue or redo his exercises even after the course has ended.
The exercises are designed to run on the provided NUCLEO STM32L552 board. This board is kept by the student at the end of the class.
For team-based training, the NXP LPC55S69-EVK board is supported in a Windows 10 only environment. This requires installation of the MCUXpresso tool prior to the class.
