Percepio: Tracealyzer 3.1 supports RTOS trace using just a standard USB cable

Percepio announced Tracealyzer 3.1. The improved tool adds support for trace streaming over USB, provides detection of dynamic memory leaks, and includes many other updates to get up and running even quicker. The trace recorder library is now easier to configure for streaming over custom interfaces, and includes support for USB streaming on STM32 (easily adapted for other MCUs). USB offers excellent performance for RTOS tracing and over 600 KB/s has been measured on an STM32 using USB 2, several times more than required. Other stream ports include TCP/IP (example for lwIP) and SEGGER J-Link debug probes. Tracealyzer 3.1 can also receive trace streams via Windows COM ports, e.g. from USB CDC connections, UART connections or any virtual COM port provided by other target interfaces.

Tracealyzer v3.1 has also been extended to identify memory leaks in systems that use dynamic memory allocation. It can record memory allocation events (e.g. malloc, free) 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 has been improved significantly to simplify integration and now provides a common API for both streaming and snapshot recording that makes it easier to get started with snapshot recording and then switch to streaming, or vice versa.
