Investigating ARM Cortex® M33 core with TrustZone® – Setting up your environment and creating your first project with MCUXpresso IDE

This is the second of my 17-part video tutorial series investigating the ARM Cortex® M33 core with TrustZone® security extension. My preferred platform for this investigation is the LPC55S69 from NXP, and of course it is necessary to have a development board and IDE. So I’m using the LPC55S69-EVK with NXP’s MCUXpresso IDE and the MCUXpresso Software Development Kit (SDK).

This week the video is really low on theory, but high on practical, step-by-step information to get started with these tools. Maybe you are similar to me, and make the same mistake every time?? I get the self-assembly furniture home from the store, or open the box containing the new development board and just get started. At some point it doesn’t work properly and that’s the time I must read the supporting information.

Well, with this video I show you beginning-to-end in just over 10 minutes, and you won’t need to refer to any other material.

During the video I show you the following steps:

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:

This is my first quick post showing the unboxing of the LPC55S69-EVK and the out-of-box experience.

The LPC55S69-EVK board comes on-board debug probe. The board includes the LPC4322JET100 device which acts like NXP LPC-Link2 debug probe:

But it is easily possible to use the board with an external debug probe or re-program the onboard one as a SEGGER J-Link debug probe.
