I’ve imported the FreeRTOS Demo Project as described and everything worked fine. Now I want to see the trace recording of the demo. I’ve installed FreeRTOS+Trace but I don’t know how to export the memory to a dump file so I can open it with FreeRTOS+Trace. The memory view in eclipse doesn’t show any data. Any idea how to do this? Thanks ---

One of those icons is “1010” with an arrow pointing up at to the right - hover over it and it says “Export” - press it and you can define a region of RAM and a file name you would like to save the RAM too. You should be able to use the name of the trace recorder buffer variable as the start address, and just make the size much bigger than it needs to be (as the +Trace tool will know where the start and end are).

I am in front of it, hooked up with my laptop and debugger. And I see: indeed, it has a problem. Maybe just a one… If that button is disabled: are you in an active debug session? Another way is to use the gdb dump command, see [http://mcuoneclipse.com/2015/01/05/updated-percepio-tracealyzer-and-trace-library-to-version-v2-7-0/](http://mcuoneclipse.com/2015/01/05/updated-percepio-tracealyzer-and-trace-library-to-version-v2-7-0/) Or: if you are using a Segger J-Link, then the Percepio Tracealizer can directly read from the target using the J-Link.
