Troubleshooting J-Link RTT streaming

The easiest way to stream Tracealyzer traces from an RTOS is often via a SEGGER J-Link debug probe, using the RTT feature. This relies on a RAM buffer that is read by the J-Link probe while the target system is executing. This is usually fast and reliable, but in case you encounter issues, please check [...]

Tracing TCP Sockets in FreeRTOS

By default, the Tracealyzer Recorder Library allows for tracing two kinds of information: (1) RTOS kernel events such as context-switches and RTOS API calls, and (2) User Events in the application code, such as debug logging, state changes and variable values. With the release of Tracealyzer 4.2.9 we added a third way to trace [...]
