The cool thing about studying in Kiruna, Sweden's northernmost city, is that you may get to blast stuff into space on a rocket. The city is home to Esrange, a vast commercial and research rocket range, and the local technical university takes advantage of that with a menu of suitable courses, with names like "Spacecraft [...]

India, Norway, France … there has been a flurry of interest around Percepio’s free academic Tracealyzer licenses lately. End of summer and beginning of the fall semester probably plays a role here, as does our announcement a few weeks ago. One of the free licenses was awarded to Anil Joseph, student at the Birla Institute [...]

Percepio has its roots in academia, Mälardalens Högskola in Västerås, Sweden, to be precise, and we have long supported both technical universities and their students with heavily discounted Tracealyzer licenses. Today we are taking this to the next level with the launch of a completely free site license for qualifying schools. "The embedded community has [...]

When Amazon Web Services (AWS) launched their IoT platform Amazon FreeRTOS last November, Percepio was one of four launch partners presented on stage. This week AWS published an article about AWS IoT development using Amazon FreeRTOS, Percepio Tracealyzer and the NXP OM40007 IoT kit, written by Percepio CEO and founder Johan Kraft. "Tracing Amazon FreeRTOS [...]

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 [...]

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 [...]

I (Mike) was travelling to Barcelona for the RISC-V Workshop earlier this month. As I walked through the Barcelona airport I looked up and saw some big ass fans. I took a quick picture, enlarged the logo, and sure enough – it really was a Big Ass Fan! It's always cool to see a Tracealyzer customer's [...]

Percepio's Senior Drone Builder and Support Engineer Niclas Lindblom with his Embedded World drone. We knew we had to have something special. We knew we were going to show Tracealyzer 4 at Embedded World 2018, and we wanted the world to take notice – it was after all the largest improvement in at [...]

Percepio has released Tracealyzer version 4.1 with support for Micrium µC/OS-III. We have also added support for RTOS tracing via Arm's ITM interface (Instrumentation Trace Macrocell), that allows very fast streaming of software trace data with low overhead. “Tracealyzer 4 is such a massive improvement over previous versions and as we have been working closely [...]

You may have heard about the General Data Protection Regulation, better known as GDPR, which is the new regulatory framework for managing personal data of European Union citizens; it comes into force on 25 May, 2018. Since Percepio is based in Sweden, which is a member of the European Union, and have a lot of [...]

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 [...]

We have talked about it for six months, and worked on it for much longer than that, but today it is finally here - Tracealyzer 4! Starting today, you can download the new version of Percepio's powerful visualization tool and try it out for yourself. If you use Tracealyzer today, the first thing you will [...]
