Tracealyzer and LPCXpresso

Posted by koenvda on February 7, 2017


I want to use the Trace functions of FreeRTOS on the LPC1830.

I use the LPCXpresso software. With this guide: http://www.freertos.org/FreeRTOS-Plus/FreeRTOSPlusUDP/EmbeddedEthernetExamples/RTOSUDPandCLILPC1830NGX.shtml#usingfreertosplustrace

Every time I select the &RecorderData in the Memory Browser and I export the data (with the sizeof( RecorderDataType )) i can't open it in Tracealyzer for FreeRTOS. The error is: "Failed to load trace: Cannot load Counter Name data because an invalid index " was read from the registry. "

does someone now this error?

That is a very old demo and the trace files have changed a number of types since it was created.

Does that example build the code from the /FreeRTOS-Plus/Source/FreeRTOS-Plus-Trace directory? Or does it have a local copy of the trace functions?

It might be better to take a trace config file from one of the newer demos. You could use the one from the maintained Win32 demo (from the FreeRTOS/Demo/Win32-MingW directory) but you would have the change the port from Win32 to Cortex-M.

There was a problem with the Tracealyzer. I have a older version now which does the trick.
