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 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 [...]

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 [...]
