I'm trying to get the Trace running on my Atmel644 but encountering alot of issues. At first I enabled the USE_TRACE_FACILITY in the FreeRTOSConfig.h. After that I declared a #define BUFFER_SIZE = 100; struct xBuffer { unsigned long ulDummy; // This will get alligned char pcBuffer[ BUFFER_SIZE ]; }; struct xBuffer pcBufferStruct;
as said in an older post.
Now I can start the vTaskStartTrace(pcBufferStruct.pcBuffer, BUFFER_SIZE) in my main function and the ulTaskEndTrace() at the end of one task. Everything's fine until this point.
Now I have no clue how to get the data out of my memory. I'm using AVRStudio by the way. I tried to use the Quickwatch function in debug mode on pcBufferStruct.pcBuffer but it's only showing 100 zeros, no data inserted there. The other problem is, that this is only in debug mode in AVRSTudio.
Even if I could get the Trace to run, I must get the stack out of my Atmel644. How do I do this without any debugger like ICE50? I've only the STK500.
So, I know, alot of questions but I hope that someone could answer one or two.
Your help is appreciated, thx, Tobias

Put BreakPoint in AVRStudio here
void vTaskSwitchContext( void ) .............. ................... /* listGET_OWNER_OF_NEXT_ENTRY walks t............ same priority get an equal share of the processor time. */ listGET_OWNER_OF_NEXT_ENTRY( pxCurrentTCB, ............. Here!!!!->>>>>vWriteTraceToBuffer(); }
