Trace on ARM7

Is it possilbe to Trace the Scheduler directly on the ARM7 Controller not only in Dos? Im using a Philips LPC2138 Controller on an Keil board. Thanks, sensej

V2.6.1 has the changes, but in this version the definition: #define tskSIZE_OF_EACH_TRACE_LINE            ( sizeof( unsigned portLONG ) + sizeof( unsigned portCHAR ) ) should be: #define tskSIZE_OF_EACH_TRACE_LINE            ( sizeof( unsigned portLONG ) + sizeof( unsigned portLONG ) ) but this does not make too much of a problem.

Thanks for quick answer. If I do so my Programm ends in the DAbt_Handler(0x00002CC0). Is there any bad definition of Memory?

Hi, If your vWriteTraceToBuffer() trace macro is as defined by the V2.6.1 release and the tskSIZE_OF_EACH_TRACE_LINE definition is corrected as per the other post in this thread then the only other thing I can suggest is to check that the trace buffer is aligned on a four byte boundary.  I’m not sure if the compiler will do this automatically for a byte array.  You can force it using a #pragma, or by placing it in a struct following a long as per: struct xBuffer {     unsigned long ulDummy; // This will get alligned     char cTraceBuffer[ BUFFER_SIZE ]; } Failing this, you can send me your modified file (presumably trace.c) and I can take a look at it (use the email address form the contacts page of the FreeRTOS.org web site).  Which processor are you using?  I might be able to give it a go.

I meant tasks.c as the modified file – not trace.c!

If the trace is already started when the scheduler starts then the time stamp will be zero – as in this file segment.
