unable to get trace data

Mark Bohanon

Hello,

I am unable to get trace data using trace dump command in DS-5.  I'm using ARM FVP Cortex A8 Bare Metal Debug.  I can get traces just fine, but I'm not able to export it to a file using trace dump. 

I get following in commands window.

Writing trace dump from trace capture device FMTrace.

ERROR(ECMD3): Failed to get 1,048,576 bytes of trace data

Any Ideas?

    Hi Mark,

    I think you are using an older version of DS-5.

    If i try the same with the latest version of DS-5 (v5.23.1) then

    i) there is no FVP Cortex-A8 model included, and

    ii) dumping trace from the FVP VE Cortex-A9-x4 works fine and I get :

    wait

    continue

    interrupt

    Execution stopped in SYS mode at S:0x80000740

    On core ARM_Cortex-A9MP_0 (ID 0)

    In primes.c

    S:0x80000740   147,35   for( i=0; i <= 100000; i++) { __nop(); }

                                                          ^^^^^^^^^

    trace dump c:\temp\A9x4_FVP_trace

    Writing trace dump to c:\temp\A9x4_FVP_trace

    Writing trace dump from trace capture device FMTrace.

    trace dump complete

    According to the DS-5 changelog at http://ds.arm.com/developer-resources/ds-5-development-studio-changelog/  the Cortex-A8 FVP was removed in v5.22, so I think you are using v5.21 or earlier.

    If you try upgrading to the latest version of DS-5 then everything should be fine.

    I hope that helps ?
