Västerås, Sweden, 20th February 2018 * * * Percepio announces a major update of Tracealyzer, its industry-leading tool for visual software tracing of RTOS-based embedded systems and IoT devices. Tracealyzer version 4 has been redesigned from the bottom up.
If your systems' real-time behavior would be noticeably affected by the tracing when using J-Link RTT streaming, this is most likely caused by insufficient throughput, causing the J-Link RTT transfer to block execution. If it works good in snapshot mode, the streaming mode should normally be even faster, otherwise there is blocking in the streaming channel. [...]

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.

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 [...]

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 [...]
The use of Real-Time Operating System (RTOS) is increasingly common in embedded software designs, as an RTOS makes it easy to divide your code into smaller blocks, tasks, which execute seemingly in parallel and independent of each other.
