Last summer, we added support for the open source Zephyr RTOS to Tracealyzer. Today, in recognition of the potential of Zephyr to become the leading independent platform for small IoT devices, Percepio joined the Zephyr Project as a Silver sponsor. Percepio made significant contributions to the Zephyr source code, extending the tracing subsystem to allow full tracing of Zephyr applications in line with the capabilities of Tracealyzer.
