Continuous Observability on Zephyr RTOS Now Supported

Oct 22, 2026

Enabling embedded engineers to automatically detect, capture and diagnose runtime anomalies and faults, Percepio Detect 2026.1 has just been released. This adds comprehensive Zephyr real-time operating system (RTOS) support to its widely-used Continuous Observability platform.

Software-defined vehicles demand a new level of runtime visibility

Oct 14, 2026

As the transition towards software-defined vehicles (SDVs) accelerates, manufacturers are consolidating functions onto increasingly powerful compute platforms. Systems that were once isolated are now integrated, and software lifecycles are extended through over-the-air updates. Features that previously existed within the boundaries of individual ECUs now interact across domains, delivering architectures that are more capable, but also significantly more complex to reason about. System behaviour is now increasingly shaped by interactions between concurrently executing components, communication pathways and timing relationships that are difficult to fully understand through static analysis or conventional testing alone.

Beyond writing code – Why system understanding is becoming a key skill

Sep 15, 2026

We graduate engineers who can explain every line of code yet struggle to explain why their systems fail in the field.
…
Embedded systems rarely fail line by line. More often, failures emerge in timing, scheduling, and runtime interactions that are difficult to observe through static development methods alone.
…
In an AI-assisted development world, the focus is no longer on teaching how to code but on developing system understanding.

New Appointment at Percepio Set to Drive Long-Term Product Development Activities

Sep 1, 2026

In order to extended the scope of its product offering and catalyse further commercial growth, specialist in observability technology for embedded and edge-based systems Percepio has confirmed Andreas Klintemyr as its new Product Lead.

Completing the Audit Trail: Why Embedded Teams Need Runtime Observability

Aug 25, 2026

Embedded engineers regularly encounter failures that are difficult to reproduce despite using the same firmware image throughout testing. A system may pass hundreds of test cycles before a watchdog reset occurs, a communication stack may hang only after many hours of operation, or a latency spike may appear intermittently and then disappear in subsequent runs. Continuous observability (CO) extends the audit trail into runtime execution. Rather than treating observability solely as a debugging technique, it becomes an ongoing capability that captures execution data throughout development, integration, testing, and validation.

Defence Capability doesn’t Sleep Anymore

Aug 6, 2026

Modern defence platforms increasingly gain capability through frequent software updates rather than major hardware upgrades. That shift brings speed, flexibility, and lower cost, but it also exposes a growing mismatch: capability is delivered continuously, while software assurance is still often treated as a one-time activity before deployment.

Traditional verification remains essential. Unit testing, static analysis, integration testing, and qualification provide the foundation for safe and reliable embedded systems. But they cannot fully reveal how software behaves under real operational conditions: timing pressure, task contention, hardware interactions, environmental factors, and complex integration scenarios. Some faults only emerge after deployment, triggered by rare combinations of runtime events that are difficult or impossible to reproduce in the laboratory.

Continued Operational Assurance in Software-Defined Medical Devices

Jul 29, 2026

In his latest video interview EPDT’s Editor-in-Chief Mike Green talks with Andreas Lifvendahl, CEO of Percepio about the emerging era of software-defined medical devices and how consistent behaviour can be maintained on an ongoing basis.

Clinical trials are an ideal opportunity not only to validate clinical outcomes but also to understand software behaviour under real operating conditions.

“Today it’s a lot of ad hoc debugging… then you remove the printf’s and alike completely, and then you’re basically flying blind from that point on. … But development never stops. We are only a small piece of a much larger puzzle—but it’s a puzzle that is rapidly growing and evolving” says Lifvendahl, CEO at Percepio.

The hidden flaw in real-time systems teaching

May 18, 2026

Florent Goutailler, Associate Professor at Télécom Saint-Etienne, describes how adding a runtime visualisation tool to his FreeRTOS course closed that gap – and transformed the way his students approach engineering problems.

“For many years, I observed the same pattern: students could write code that compiled and ran, but when something didn’t behave as expected, they struggled to understand why.”

SOFTWARE ASSURANCE, OSSERVABILITÀ RUNTIME

Detecting silent failures and improving runtime security

May 5, 2026

Why are non-crashing failures becoming more common in modern embedded designs?
Embedded systems have become far more complex over the last decade. We now see multicore processors, RTOS-based concurrency, third-party middleware, connectivity stacks, and increasingly AI or data-driven workloads running alongside traditional control software.

Percepio Tracealyzer provided the scalability and modularity as key enablers for BMW engineers

May 5, 2026

“We do embedded software traces for automotive and other industrial software applications,” said Andreas Lifvendahl, CEO of Percepio. “We make sure the software behaves.” Tracealyzer provided insight into software runtime performance, helping engineers monitor execution behaviour during development and testing in BMW’s work on software-defined vehicles (SDVs).

Verifying multi-threaded embedded systems with software tracing

Apr 3, 2026

Embedded software often also needs to meet real-time requirements. For example, a control system might have a requirement to output control signals to a motor controller every 5 milliseconds, where any additional delay is considered a failure. Such requirements are not only affected by the execution time of the specific thread, but also by dependencies on other threads. Thus, verifying real-time requirements is about more than measuring timing metrics. It is also about identifying potential risks from thread interactions that may affect the timing requirements.

So, how do you verify that a design is good from a multi-threading perspective?
