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 [...]
Last month at Embedded Conference Scandinavia, Percepio founder Dr. Johan Kraft made a very well received presentation called "Common RTOS-related bugs – How to Avoid and Detect".

Read Mike Skrtic's blog on Electronic Specifier, or Download Tracealyzer and see the whole picture for yourself. [...]
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. They needed to perform some in depth analysis of their code timing, which runs on an STM32F4xx MCU under FreeRTOS. The best single characteristic of Tracealyzer for FreeRTOS can be summed up [...]

When developing embedded software, a good understanding of the real-time behavior is vital. At Percepio we develop the Tracealyzer tools for RTOS trace visualization, but this post is about a related technology from ARM that we believe is of general interest to any developer using ARM-based MCUs. Having some form of diagnostic logging/tracing is necessary in most [...]
We have just published our updated website, I hope you like the new design! There are a few issues remaining, especially the product pages don't look great at the moment. This will be fixed within the next days.
Today I received an interesting new board to play with, a Computex board with a powerful Renesas RZ/A1 processor shown below. This has an ARM Cortex-A9 core at 400 MHz and 3 MB on-chip RAM. And if that is not enough, there is another 32 MB RAM on the board. Quite a lot of power [...]

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 [...]

If you have kids and like to build stuff, you might have built a soapbox car at some point. At least I did last summer. For me, an obvious next step was to consider adding an electric motor. I never found the time, but would have loved a project like that. I therefore got quite [...]
In the end of February we exhibited at Embedded World, which is the largest Embedded Systems trade show in the world with about 1000 exhibitors and 25,000 visitors.

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 [...]

A major limitation with our previous Tracealyzer tools has been the limited trace length and/or large RAM requirements. The recorder could only store as much trace as its RAM buffer allowed. This could at most give a few seconds of trace on most microcontrollers. Can be very valuable, but also rather restricted in many cases. [...]

If asserts are enabled the recorder configuration (trcConfig.h), this error is generated in uiTraceGetPriorityProperty when a task has an "object handle" value larger than expected. Our FreeRTOS recorder assignes each task an 8-bit "object handle" (the "id" parameter in uiTraceGetPriorityProperty), which should be in the range [1..NTask]. The NTask constant is defined in trcConfig.h and [...]
