Do you struggle with bugs that are difficult to replicate and isolate? Most embedded software developers encounter such problems now and then. With increasingly complex multi-threaded RTOS-based systems, such issues are likely to become more and more common in the future. They can be very difficult and time consuming to solve, and sometimes developers resort [...]
It's that time of year again – late December in Sweden means snow (mostly) and darkness (always), but it also means that the Christmas holiday is coming. Most of our staff will go on a well-deserved vacation break next week, so expect that it may take a little longer than usual for us to respond to [...]
A completely revamped user interface and a much improved live view are two of the most prominent features of the upcoming Tracealyzer 4, which we showed for the first time at Arm TechCon in October. We put together a series of short introduction videos where Tracealyzer 4 shows off its abilities. First out is the [...]
November was a good month for Percepio and Tracealyzer. We saw record sales, a lot of interest in the Tracealyzer 4 preview videos and everything culminated on the 29th with the release of Tracealyzer v3.3 supporting Amazon FreeRTOS, just released by Amazon Web Services along with several new IoT offerings. We believe Amazon Web Services has taken [...]
Amazon Web Services launched their own RTOS yesterday, as part of a major improvement of its IoT offerings. We're happy to announce that Tracealyzer version 3.3, which we released yesterday, fully supports Amazon FreeRTOS, the new IoT microcontroller operating system from Amazon Web Services (AWS). AWS and Percepio have collaborated to provide Tracealyzer support for [...]

If you weren't there, you can still get a feel for the new product through a short video we have put together. [...]
Deadlock is a well-known phenomenon even outside the embedded world. For a general description of deadlock, see this article; it is far better than anything I could ever hope to write. But I digress – back to deadlocks in RTOS-related programming. A clear indication that you may have a deadlock problem is when multiple tasks [...]
Percepio's stand at ArmTechCon. ArmTechCon 2017 is over and we have packed up and left. We spent two days talking to users and meeting partners, and we showed the upcoming Tracealyzer version 4 for the first time. We will have more to say about both Tracealyzer 4 and ArmTechCon in the coming weeks, but there's one little [...]
Priority inversion at work – the high-priority (red) task is blocked by lower priority tasks. 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. If necessary, the RTOS can even pre-empt the running task, forcing it to yield the CPU to [...]
Our Korean distributor Dioiz is running a hands-on seminar on embedded development with, among other tools, Tracealyzer this week. It is sold out by now, but there will be a second event on November 22 and Dioiz has let us know that applications are welcome. More info here – note though that both the invitation and the [...]
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”. When your task experiences jitter, it sometimes has to [...]

This makes Tracealyzer applicable to a wider range of development setups. Today we are happy to present version 3.2 of Tracealyzer for FreeRTOS. The new version is available for download from percepio.com/download/ immediately. [...]
There is no doubt a learning curve when you begin using a real-time operating system (RTOS) in your development. You will work at a higher abstraction level, using more or less parallel tasks rather than just subroutines, and you will need to consider how your tasks shall share data and the processor time with each [...]

Niclas Lindblom Sr. FAE at Percepio Not that long-ago, developers thought that a high-level language was not really needed when building embedded applications. Writing a good UART driver in assembler was done in only a day or two, so why bother with C? Besides, even if you wrote in C, who could trust that [...]
Niclas Lindblom Sr. FAE at Percepio As you might know, our Tracealyzer tools allows you to record and visualize the real-time behavior of your RTOS-based firmware. In previous blogs, I’ve talked about the possibility of streaming the trace data from your board, and today we’ll consider one such specific case - USB CDC. A few months [...]

The use of a Real-Time Operating System (RTOS) is increasingly common in embedded software designs. An RTOS makes it easy to divide your code into smaller blocks, tasks, which execute seemingly in parallel and independent of each other, as described in the first article in the RTOS 101 series. Having fully independent tasks is [...]
Steve Evans of Open Pilot Next Generation (OPNG) explains how they have used Percepio Tracealyzer to finely tune their flight controllers and ensure deterministic performance.

Software tracing comes in two main flavors, software-defined trace and hardware-defined trace. Hardware-defined trace means that the processor outputs a trace of low-level software events, such as control-flow branches and exceptions/interrupts. The resulting trace is very detailed and can therefore be overwhelming - you don't see the forest for all the trees! Software-defined trace means [...]

An updated version is now available of Tracealyzer for FreeRTOS. This solves a minor issue with task names containing the substring "idle", which previously were mistakenly assumed to be the idle task (which is treated differently).
We have now released Tracealyzer for FreeRTOS version 3.0.5, with some improvements in the documentation and two bug fixes in the snapshot recorder.
When developing firmware using a Real-Time Operating System (RTOS), how do you measure the software performance? One important aspect of performance analysis is response time, the time from point A to point B in the code, e.g., from when a task is activated until it is completed. This can be measured in many ways, e.g., [...]

Software-based tracing always means some processing overhead, where the exact amount is f x e, where f is the average event frequency and e is the average execution time for storing an event. This is very dependent on your application and processor. The more RTOS calls, the larger overhead. The faster processor, the less overhead. Let's put in some [...]
