Streaming trace on SEGGER J-Link

A major limitation with our previous Tracealyzer tools has been the limited trace length and/or large RAM requirements. The recorder could only store as much trace as its RAM buffer allowed. This could at most give a few seconds of trace on most microcontrollers. Can be very valuable, but also rather restricted in many cases. [...]

How to set ISR_TAILCHAINING_THRESHOLD?

To trace the execution of exception/interrupt handlers (ISRs), you need to call vTraceStoreISRBegin and vTraceStoreISREnd in the beginning and in the end of the handler function. The vTraceStoreISREnd routine normally assumes a return to the previously executing task. But sometimes another ISR is pending and executes in direct sequence, making this assumption incorrect. For instance, ARM Cortex-M devices [...]

Why do I get “error: ‘uxPendedTicks’ undeclared”?

If you get this error when compiling the recorder, you are probably using an older version of FreeRTOS (v7.5.x or earlier) together with a newer version of the recorder library. The FreeRTOS variable 'uxPendedTicks' was before v7.5.2 named 'uxMissedTicks', so you need to replace uxPendedTicks with uxMissedTicks in the definition of traceTASK_INCREMENT_TICK in trcKernelPort.h Update: [...]

In this case, the name is set to "ISR using Object", where Object is the queue [...]
