Embedded Systems Engineering

Passionate about the Yocto Project, AOSP, Linux kernel development, microcontrollers, FPGAs and the electronics behind.

When not building innovative embedded systems solutions, you’ll find me speaking at conferences, getting deeper into electronics by doing an additional distance university graduation or capturing urban wildlife through my lens.

As embedded systems become increasingly interconnected, the demand for robust platform security and integrity has surged. Trusted Platform Modules (TPM), currently in version 2.0, are becoming increasingly beneficial for enhancing security in embedded systems. TPMs provide hardware-backed mechanisms for critical functions such as random number generation, cryptographic key generation, key binding and data sealing.

Patching Unpatchable Files

In the Yocto world, the .bbappend file is a well-known and documented mechanism for altering recipe files, and an essential part of daily operations. While not common, there are instances where it becomes necessary to modify other file types, such as .inc or .bbclass, which do not offer an equivalent append mechanism. This session will summarize various strategies for effectively handling these file types when patching cannot be avoided.

Yocto on the Edge - Unusual challenges when building not so embedded systems

Building embedded systems with Yocto on ARM platforms is a common practice, but when the products move further to the edge and become less “embedded,” new challenges arise. In this session, we will explore the requirements and challenges faced when developing Yocto-based systems for edge computing based on Intel.
