Booting Windows from USB drive

NXP: designing IoT devices with secure boot

NXP has a webinar for IoT makers, talking about secure booting. ‘Webinar’ scared me, but there’s no registration required. 🙂

Watch this on-demand presentation to learn how to:
* Manage the life cycle of an IoT edge node from development to deployment.
* Leverage hardware and software offerings available with the Kinetis MCU portfolio that can help you protect against attacks.
* Ease the burden of secure IoT edge node development using new processors and architectures from ARM.
