A Month of Good News

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 [...]

Tracealyzer 4: see more with Intervals and State Graphs

This is our third preview video of Tracealyzer 4, due out early next year, and this time we focus on two entirely new features: State Graphs and Intervals. Both features allow you to customize the visualization and analysis for your own system and the issue at hand. State Graphs can be created automatically from your trace, [...]

Tracealyzer 4 lets you see network activity

Welcome to a second glimpse of Tracealyzer 4, showing how network activity can be visualized together with the RTOS events. This way, developers of connected IoT systems can get a wider perspective of their system's real-time behavior. https://www.youtube.com/watch?v=K1O4AE4TEbE In this brief example we display events from a TCP/IP stack, but the same technique can be used [...]

Welcome to a first look at Tracealyzer 4

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 last week. If you weren't there, you can still get a feel for the new product through a short video we have put together. [...]

RTOS Debugging: Everybody wants the fork

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 [...]

RTOS Debugging: When the important stuff has to wait

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 [...]

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. 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 [...]

Submit your trace – get a $25 gift card

A research group at Mälardalen University here in Västerås, Sweden, is investigating how RTOS trace tools like Percepio Tracealyzer can be extended for testing purposes and automatically detect bugs related to concurrency and timing. To validate their research, they need real-world bug examples. We at Percepio want to help them obtain RTOS traces, recorded with Tracealyzer, [...]
