Percepio Tracealyzer v4.5 visual trace diagnostics software

Percepio has announced version 4.5 of its visual trace diagnostics software, Tracealyzer, with support for the Espressif ESP32 MCU and the open-source Zephyr RTOS, as well as improved integration with Lauterbach uTrace and a range of other enhancements.

Zephyr is a safe, secure and scalable open-source RTOS that supports multiple hardware architectures. Percepio’s trace recorder library has now been adapted and integrated with Zephyr v2.6. This means that Tracealyzer support is easily accessible as a configuration option when setting up a new Zephyr project. Version 4.5 offers beta-level support for Zephyr, serving as an innovative complement to traditional source-code debuggers.

The visual timeline and powerful overviews Tracealyzer provides make it easy to spot anomalies in IoT software. This lets users speed up debugging, analyse the software design and optimise performance. With this insight, Zephyr developers should be empowered to make better products in less time and at lower cost.

The software also adds support for Espressif ESP32 microcontrollers. It is now able to capture traces from Espressif’s single- and multicore versions of FreeRTOS and show live-streamed traces from both cores at the same time.

The latest version further offers improved support for the STLINK-V3 debug probe and includes the support package required to use Tracealyzer with a Lauterbach uTrace probe. It is also the first official version to include support for Percepio DevAlert, a cloud service for monitoring and remote diagnostics of IoT devices during testing and deployment.
