Tracealyzer adds extra streaming and other features

15th December 2016 Tamworth UK: Phaedrus Systems, the leading specialist in the support of engineers at all stages of embedded safety-critical and high-integrity projects, has announced that Tracelyzer , the RTOS visualization tool from Percepio, now provides USB trace streaming - the transfer of data on RTOS behaviour to a host PC.

The new release, Tracealyzer v3.1, also provides detection of dynamic memory leaks, and includes many other updates to get up and running even quicker.

" Tracealyzer v3.1 is the first RTOS trace tool to support RTOS trace using just a standard USB cable, allowing you to use any debug probe in parallel," said Chris Hills, CTO of Phaedrus Systems "The other enhancements in this release lay a solid foundation for vast improvements of the analysis capabilities that Percepio plans for Tracealyzer during 2017.”

The enhancements include making the trace recorder library 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.

About Tracealyzer

Percepio’s market-leading visualization offers 25+ views, which are cleverly interconnected to allow viewing the trace from multiple perspectives, for instance CPU usage, memory allocation, task synchronization and communication events, as well as selected state variables and input/output values.

The insight provided by Tracealyzer facilitates debugging, validation, profiling, documentation and training. This can help avoid weeks of troubleshooting and vastly increase development speed.
