Don’t Get Bogged Down in 3rd Party RTOS Code

January 9, 2024 | 5 min read

It’s midnight the day before the product release and your system just crashed. As you follow the execution back from the point of the fault, you find yourself deep inside the Real-Time Operating System (RTOS) code. If you don’t have professional support, your only option is to try and figure out why the RTOS is failing yourself.

Is It “Penny Wise” to Use Free Tools?

November 20, 2023 | 5 min read

The origin of the phrase “penny wise and pound foolish” comes from the 1621 work The Anatomy of Melancholy by Robert Burton. The idea behind this phrase is that we sometimes concentrate so hard on small costs that we can overlook larger opportunities to reduce costs or increase gains. This mindset has beset embedded development for quite some time and continues to do so.

Hidden “Royalties” Can Blow Your Budget and Your Project

October 31, 2023 | 3 min read

It’s relatively easy to design an embedded system using an excessively powerful microprocessor with a plentiful amount of memory. However, this is generally not the reality in the resource constrained world of deeply embedded devices.

Defense Mechanisms: Combatting Embedded Insecurity

October 6, 2023 | 7 min read

Securing Embedded Systems: Balancing hardware and software measures. Hardware options like anti-tampering, lock-step execution, and anti-glitch protect firmware. Software best practices include rigorous testing and careful handling of function pointers. Together, they form a robust defense.

Isn’t it About Time for a Standard RTOS API?

May 24, 2023 | 5 min read

Proprietary RTOSes with unique APIs dominate the embedded MCU landscape. While some APIs excel, others fall short. Surprisingly, the disparity between good and average RTOS APIs is minimal—they mostly get the job done. However, after 30+ years, it's clear that proprietary RTOS APIs negatively impact embedded development and our industry as a whole.

Reducing safety and security risks for embedded systems

May 1, 2023 | 7 min read

Practical tips for reducing risks include implementing secure boot and update mechanisms, using secure communication protocols, and conducting regular security audits. It also highlights the role of hardware-based security measures in protecting embedded systems from attacks. This resource is valuable for anyone involved in designing, developing, or maintaining embedded systems.

Product of the Week: PX5 RTOS with Arm TrustZone Support

May 1, 2023 | 2 min read

Safety-critical, real-time systems today — such as automotive, IoT, industrial, mobile, and other MCU-based devices — necessitate a high level of security and protection, and the ability to perform predictable and deterministic functions within a secure environment that can manage various components at once.

New PX5 RTOS Boasts Native Support for POSIX pthreads API

February 9, 2023 | 11 min read

The PX5 RTOS includes native support for POSIX pthreads. The new feature enables developers to use standard pthreads APIs, simplifying the development of multithreaded applications on PX5 RTOS. The Max Maxfield article highlights the benefits of the new features and their potential impact on embedded systems development.
