Investigating ARM Cortex® M33 core with TrustZone® – Unboxing and Getting Started

Hi, I’m Mark from embeddedpro® in the United Kingdom and Erich’s allowed me to be a guest blogger here on mcuoneclipse. At many industry events, trade shows and conferences I’ve seen and given presentations about TrustZone®, but have not found tutorials or practical information online.

So I’m creating a 17 part video tutorial series (it will be published weekly here) investigating the ARM Cortex® M33 core with the TrustZone® security extension. Each week from now until the end-of-year holidays I will let you know what I’ve found out with a blog here, and a video blog on youtube. My friends at NXP have given me a LPC55S69-EVK board as the basis for my experiments:

Getting Control over a 50 Watt CO2 Laser Cutter from China

There are people around me who think I’m crazy. And they are probably right. Who else would buy a machine from someone he does not know. I have to pay upfront. It is not clear how things will get delivered, what gets delivered, or if it gets delivered at all. Up to the point I can lose the money I have spent. Best of all: that machine is dangerous enough to potentially kill me. And it has the potential to put my home on fire too. Well, that sounds like an exciting weekend project, or not?
