Percepio today announced Tracealyzer version 4.5 with support for the Espressif ESP32 MCU, the open-source Zephyr RTOS, improved integration with Lauterbach uTrace, and a range of other enhancements.
In this blog post, we will see how Tracealyzer can be used to quickly and efficiently evaluate multiple implementations of an algorithm in Python, a language that is becoming more common in embedded application development as most machine learning frameworks are implemented in Python.
In this post, we’re going to understand how the combination of LTTng and Tracealyzer can shine light on how compiler options impact performance. The method discussed can come in handy whenever we are evaluating the performance of multiple candidate implementations of a particular feature.

Your organization can get to market faster with higher-quality products when given better insight into the “dark side of the code”—the actual behavior of the full software system. Intended and actual behavior may differ in myriad ways that are not apparent from the source code
The real test of IoT devices comes after shipping, when thousands of end users start using your product, sometimes in unexpected and untested ways. No software is entirely bug free, so some users will run into those remaining bugs. The question is how many and what you do about it.
We released Tracealyzer version 4.4.2 yesterday, with support for symmetric multiprocessing systems running Azure RTOS ThreadX SMP. The new release also brings improved support for trace streaming over STLINK-V3 debug probes.

Linux is a huge, and very different, beast compared to traditional RTOSes and other platforms we’ve supported with Tracealyzer in the past.
We got the question from a customer if we could host the Percepio License Manager server for them. And we thought – why not? That sounds like a good idea.
It could take our customer days to locate and fix a memory leak, but when they deployed Tracealyzer the same bug hunt was completed in a matter of hours.

Printf calls are SLOW. Writing 25 bytes over a 115200 baud serial line takes a whopping 2 milliseconds, not counting any string formatting. This may change the system behavior and hide the problem you are chasing. This also means that printf calls can't be used in any time critical code, such as interrupt handlers. Additional [...]
Just before the holidays, we managed to push out the last Tracealyzer update of this decade. The main new thing in version 4.3.7 is that the recorder has been updated to be compatible with the latest release, v3.07.00, of µC/OS-III. Other than that, we have made various performance and stability improvements, and fixed one bug where [...]
Percepio has a special winter offer to developers: write about a real problem solved with Tracealyzer and get a free 1-year Tracealyzer license.

This week we released version 4.3.6 of Tracealyzer, a maintenance and bugfix release – we fixed about 50 minor issues in this one.
Developing with an RTOS can make it easier to design complex applications, but while an RTOS reduces the complexity of the application source code, it does not reduce the inherent complexity of the application itself.
Sometimes you need to step away from the daily grind and set aside time to study the patterns and structures that make up an embedded application. To meet that need, Percepio now offers two online courses in embedded development with a real-time operating system.
Percepio has announced the availability of Percepio RTOS Training, a set of online courses in embedded and IoT software development.
The easiest way to stream Tracealyzer traces from an RTOS is often via a SEGGER J-Link debug probe, using the RTT feature. This relies on a RAM buffer that is read by the J-Link probe while the target system is executing. This is usually fast and reliable, but in case you encounter issues, please check [...]
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.

A clear indication that you may have a deadlock problem is when multiple tasks suddenly stop executing, although no higher priority tasks are running.
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.
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.
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.
Percepio exhibited at the Embedded Vision Summit in May, and the show hosts were kind enough to come to our booth and ask for a quick presentation of Tracealyzer and its support for the OpenVX vision programming framework. We were happy to comply; watch the video here to hear what our CEO [...]
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.
