embOS Tracealyzer gives streaming trace on SEGGER J-Link

embOS-Trace from Percepio gives a deep insight into the runtime world of SEGGER embOS using J-Link debug probes. Percepio embOS-Trace is the latest member in Percepio’s Tracealyzer family and the embOS integration has been developed in collaboration with SEGGER.

It provides continuous trace streaming of runtime events, such as scheduling, interrupt handlers, kernel calls and application events using software-defined trace
