Nov. 13, 2013. Västerås, Sweden. Percepio today announces the availability of Tracealyzer for VxWorks and Tracealyzer for Linux. Percepio's Tracealyzer tools provide an unprecedented level of insight into the run-time world of embedded software systems during development, verification and maintenance. This allows you to solve complex software problems in a fraction of the time otherwise [...]
Tracealyzer for Linux displays the scheduling priority reported by LTTng. For Linux processed with "normal" dynamic scheduling, this value is typically not meaningful. This is mainly intended for processes with static real-time priorities.
Tracealyzer for VxWorks uses the same data source as System Viewer in Wind River Workbench, but provides a more powerful visualization featuring over 20 different views that all are interconnected in clever ways. Tracealyzer is more intuitive to use and gives a much better understanding of your system. Some unique features of Tracealyzer are: Trace [...]
An update of FreeRTOS+Trace is now available, version 2.5.1, download it here. Added/improved recorder ports for Texas Instruments MSP430, NXP LPC21xx, Atmel AVR32 and Xilinx Microblaze. Fixed an issue related to tracing of FreeRTOS low-power mode/tickless idle. This works as intended now. The End User License Agreement was shown every time the application starts, if [...]
The Tracealyzer support for FreeRTOS, SafeRTOS and Micrium relies on Percepio's own recorder library. This can be used on most processors and contains ports for several common processor families, including: Arm Cortex-M devices, e.g., STM32, NXP LPC series, Renesas Synergy, etc. Arm Cortex-A9 devices, e.g. Xilinx Zynq. Renesas RX600 series Microchip PIC32 series Atmel AVR32 [...]
(This answer is only applicable for Percepio's own recorder library, used for e.g. FreeRTOS, OpenRTOS, SafeRTOS and Micrium µC/OS) Streaming mode As for v4.1.6, Tracealyzer supports streaming via SEGGER J-Link, IAR I-Jet and Keil ULINKpro/ULINKplus. Streaming is also possible in other ways, e.g. using USB CDC or a network connection. IAR users can find more [...]
(This answer is only applicable for Percepio's own recorder library, used for e.g. FreeRTOS, OpenRTOS, SafeRTOS and Micrium µC/OS) It depends if you are using snapshot or streaming mode. Snapshot mode requires a decent RAM buffer if you want a long trace. A RAM buffer of 5-10 KB can give a trace of 50-200 ms, depending on [...]
(This answer is only applicable for Percepio's own recorder library, used for e.g. FreeRTOS, OpenRTOS, SafeRTOS and Micrium µC/OS) The below table shows an example, using version 2.5.1 of the recorder library when compiled for ARM Cortex M4 (Atmel SAM4S16C) using ARM GCC v4.7.3. Recorder configuration Compiler optimization Flash usage Basic features -Os (minimum size) [...]
(This answer is only applicable for Percepio's own recorder library, used for e.g. FreeRTOS, OpenRTOS, SafeRTOS and Micrium µC/OS) Interrupt handlers (ISRs) are not recorded by default. To record ISRs, you need to add two calls in the interrupt handlers you wish to record, vTraceStoreISRBegin in the very beginning and vTraceStoreISREnd in the very end. [...]
You need to set a name for the ISR using vTraceSetISRProperties, otherwise the numeric ID stored using vTraceStoreISRBegin is displayed.
If you have interrupt handlers using interrupt-level kernel functions, but are not calling vTraceStoreISRBegin and vTraceStoreISREnd, the recorder assumes that the kernel call was made from an interrupt handler, but does not know the identity of the interrupt handler. In this case, the name is set to "ISR using Object", where Object is the queue [...]
Use vTraceSetQueueName, vTraceSetSemaphoreName or vTraceSetMutexName, as in the below example: actuatorQ = xQueueCreate(3, sizeof(QueueMessage) ); if (actuatorQ != NULL) { vTraceSetQueueName(actuatorQ, "ActuatorQueue"); // Set the name ... } else { ... // Error handling }
Our Trace Recorder Library used for FreeRTOS+Trace, SafeRTOS+Trace and Micrium µC/Trace is quite easy to port, as we have made a significant effort to generalize it. All kernel-specific definitions are located in trcKernelPort.c/.h, but you need to insert instrumentation in the kernel and add new fields to the kernel object data types. We welcome new [...]
The name is latin and means "to perceive", i.e., to become aware or conscious of something.
We are happy to announce our new distributor for Germany, Austria and Switzerland, Embedded Tools GmbH. Welcome to the Percepio family!
