Looking at Mutex Usage
We have had a few customers asking us if they can use Tracealyzer to detect when a task holds two mutexes at the same time. The answer is yes, there are in fact several ways you can do this.
Introducing DFM for Renesas Synergy
Together with our partner Renesas, we made a demo video of Percepio Device Firmware Monitor running on a Renesas AE-Cloud2 developer kit. The demonstration, which walks you through both Tracealyzer and DFM, is available as a free on-demand webinar from Renesas.
Get A Good Start With These Tracealyzer Example Projects
Over time, Percepio has built up a collection of Tracealyzer example projects and today we are releasing them to the public.
RTOS Debugging: Everybody wants the fork
A clear indication that you may have a deadlock problem is when multiple tasks suddenly stop executing, although no higher priority tasks are running.
RTOS Debugging: When the important stuff has to wait
The central idea underlying an RTOS with a fixed-priority scheduler is that a high-priority task should be scheduled ahead of one with lower priority. Yet, as a developer you have to watch out for programming pitfalls that can result in inverted priorities.
RTOS debugging: Chasing the jitter bug
When you have a task in your system that is supposed to execute at regular intervals, say for instance that it needs to read a sensor value every 5 milliseconds, then you have a system that is sensitive to random delays – also known as .jitter.
RTOS debugging: When the CPU has too much on its hands
In embedded systems using multitasking, you may run into a situation where some of your tasks run slowly or not at all. This is called task starvation (the affected tasks are starved of CPU time) and it can happen for a number of reasons.
RTOS debugging: Dealing with timing issues
There is no doubt a learning curve when you begin using a real-time operating system (RTOS) in your development. Timing, scheduling et cetera will affect your code in ways that are not directly visible in the source code.
The Future of FreeRTOS: Risc-V, More Arm, And Percepio DFM
Richard Barry, the founder of FreeRTOS, gave a presentation on the future of FreeRTOS earlier this spring. He followed FreeRTOS to Amazon Web Services where he still oversees the project, and he could confirm that it is one healthy open source product.

Getting Started with the Device Firmware Monitor (DFM)
In this post we are going to dive deeper into Device Firmware Monitor and explain what it takes to set it up and how it can be used in a typical IoT application.
Tracealyzer Opens Door to Developers
Are you using Tracealyzer today but find yourself wishing that we should have added that special missing feature? We hear you: over the next few months we are going to enable embedded and IoT developers to do many things themselves, without having to wait for new releases of Tracealyzer.
Trace in Space: Self-Assembling Telescopes
One of the many free academic licenses for Tracealyzer that Percepio has handed out this year went to Charles Sommer, research engineer on the AAReST project at Caltech in Pasadena, California. AAReST aims to construct a telescope that can be sent up in space in pieces and then assemble itself in orbit.
Linux Support Coming to Tracealyzer 4
We have good news for the growing crowd of embedded Linux developers: the next step on the Tracealyzer 4 roadmap is proper support for Linux tracing, complete with live visualization and many other great features.
How Many Bugs Do You Miss?
Computer scientist Edsger Dijkstra once said, “Program testing can be used to show the presence of bugs, but never to show their absence”. No matter how much developers test their software, they just cannot prove that there are no bugs left.
It’s Been Two Packed Days
We are ready to face another day meeting current and would-be customers. Oh – and we have a free T-shirt bonanza all day (as long as supplies last).
Future of FreeRTOS
On Tuesday, FreeRTOS founder Richard Barry spoke to a packed room here at Embedded World about the future of Amazon FreeRTOS.

Customizing the Trace Visualization
Within Tracealyzer's trace view, tasks, events and state machines are now organized into view fields, collections of tasks, intervals or events. In this post, we are going to examine how you can use those views to simplify working with Tracealyzer.
Tracing TCP Sockets in Amazon FreeRTOS
By default, the Tracealyzer Recorder Library allows for tracing two kinds of information: (1) RTOS kernel events such as context-switches and RTOS API calls, and (2) User Events in the application code, such as debug logging, state changes and variable values. With the release of Tracealyzer 4.2.9 we added a third way to trace your [...]
What’s New In Tracealyzer 4.2.9
Just in time for the winter break, we have released Tracealyzer 4.2.9 with some new improvements and bug fixes. Better support for large systems with many actors (tasks and ISRs), as the trace view can now hide inactive actors automatically. Tracealyzer will ask about enabling this feature if there are too many actors to fit [...]
Tracealyzer 4 Now Supports VxWorks

In this post, we visualise the custom interval and state machine information available in Tracealyzer and explore how we can use it to better understand our application.
Tracing adaptive applications for IoT end devices
Tiny sensor devices are key elements in IoT systems, and they need to be as energy efficient as possible. Roberto Rodriguez-Zurrunero has successfully used Tracealyzer in his research to both minimise energy consumption and fine-tune timing.
Trace streaming over TCP/IP on Xilinx Zynq
Xilinx development kit ZC702 features a Zynq 7000 programmable SoC, lots of RAM and on-board I/O connectors ranging from HDMI to Gigabit Ethernet and USB. We set out to build a Tracealyzer demo application for this board, based on FreeRTOS and lwIP, with live trace streaming over Ethernet. During this work we discovered an interesting issue [...]
Analyzing State Machines
In the previous Hands On post we introduced the concept of intervals, which is the time between any two events and can be added to the timeline. In this post, we will take the interval one step further and see how we can use Tracealyzer to monitor state machines.
Introducing the World’s First Trace Profiler for OpenVX and Embedded Vision/AI Processors
Computer vision has become a core feature for all sorts of embedded systems. Therefore we have developed Tracealyzer for OpenVX, the world's first trace profiler for OpenVX and Embedded Vision/AI processors, in collaboration with Synopsys.

Tuning Your Custom Trace Streaming for Maximum Throughput
The Tracealyzer recorder for FreeRTOS, SafeRTOS or Micrium µC/OS can be configured to stream the trace data via any interface you might have available. If you have designed your own custom stream port but are having problems getting a reliable transfer or sufficient throughput, there are several things you can try.

Tracing exceptions in Keil RTX5
When debugging or profiling your firmware, it is often important to trace Interrupt Service Routines (ISRs) such as timer interrupts or interrupts from communication interfaces. However, using a classic ”printf” call is typically not an option since it may increase the execution time of the ISR by orders of magnitude. The integrated ”exception trace” support [...]
We are Moving
Tomorrow Friday is a special day here at Percepio HQ – we're moving offices. We are not moving very far, the new office is a ten-minute walk from our current one, but it is absolutely a step up for the company. We'll have our own offices with plenty of space to grow (and we are [...]
An Unexpected Customer Meeting

Let Tracealyzer show you the big picture
When you open a trace in Tracealyzer, it usually opens to the vertical timeline. This view, which shows all activity in the system, is in many ways the core of Tracealyzer and most of the other views link back to the timeline, but with its massive amount of information it is not always the best [...]
