Tracealyzer 3.1 supports RTOS trace over USB

The latest generation Tracealyzer 3.1 has been unveiled by Percepio. According to the company, updates to the tool include support for trace streaming over USB and detection of dynamic memory leaks.

The trace recorder library is said to be easier to configure for streaming over custom interfaces, and includes support for USB streaming on STM32. Tracealyzer 3.1 is claimed to be the first RTOS trace tool to support RTOS trace using just a standard USB cable, allowing you to use any debug probe in parallel. More than 600KB/s has supposedly been measured on an STM32 MCU using USB 2.

Other stream ports include TCP/IP and SEGGER J-Link debug probes. Tracealyzer 3.1 can also receive trace streams via Windows COM ports, from USB CDC connections, UART connections or any virtual COM port provided by other target interfaces.

The tool has also been extended to identify memory leaks in systems that use dynamic memory allocation. It can record memory allocation events from multiple operating systems, and can now display such allocations that have not been released. Since the memory allocation events are linked to the task trace, the user can quickly find the context of the allocation and investigate the problem.

The recorder library provides a common API for both streaming and snapshot recording that makes it easier to switch between the two.
