Cortex®-M23, M33: Armv8-M Architecture Training with Security Extension

Get familiar with the new Armv8-M architecture (Cortex®-M23 and -M33) and learn how to write software in C and Assembler. This workshop focuses on software and covers a variety of topics, such as the TrustZone, processor architecture, extended instruction set, exception behavior, and many more. After the training, you can locate programs in memory in secure and non-secure configuration and test them - the perfect start for designing Cortex®-M23/M33 based systems.
