about DVT scripting

Hi:

We created a javescript to simulator "PC trace" on our tracepod , but didn't get the right result now. Anyone can help me ? thanks !

CCS version is 5.5.0,OS is window XP.

What we do in manually trigger was : Tools->Hardware Trace Analyzer-> PC Trace(set startaddress,buffer size in this view) , make code go into function of “startaddress” , then we can see the data in "trace viewer" and the exported csv was start from this address.

But we didn't get the same behavior when using scripts , the “trace viewer”was not waiting for buffer full and the exported csv was not started with right address .

 

Function:string

Disassembly:string

Program Address:uinteger:hex

Delta Cycles:ulong:decimal

Cycle:long:decimal

    Hello,

    You specified that you are using a xds560v2 STM emulator but also specified that you are using a Pro Trace receiver. Which exact emulator/receiver are you using?


    Thanks

    Sorry for misunderstanging , We are using "Spectrum Digital XDS560V2 STM USB Emulator_0" .

    TI__Guru**** 420760 points
    Then I assume you are using the ETB?

    Do you mean "transport type" ? We set is as ""transportType", "Pro Trace"" now, both in manual and scripting .

    Unless I'm mistaken, you should be using "ETB" for transport type unless you are using the XDS560v2 PRO TRACE emulator/receiver (with proper pins on the target). I'll confirm this when I am in the office tomorrow

    When you manually enable PC Trace via the GUI, is this the setting you are using?


    To use this setting, you need an XDS PRO TRACE receiver. Otherwise you get an error when trying to Start the trace session. Does this setting work for you?

    Yes , both "Spectrum Digital XDS560V2 STM USB Emulator_0" and "Spectrum Digital XDSPRO USB Emulator_0" can work in manually enable "transport type".

    But I modify it to XDSPRO in scripts now maybe it's more reasonable . But we still can't get the expected csv .

    could you help check following script , I modify it form CCS DVT examples. thanks !

    Hi,Ki

    Our scripts can run now and csc data is right , the reason why we couldn't get expected data was some parameters set error in analysis.

    Anyway, thanks for your warm supports .
