TMS320F28027F: During automation In DSS scripting, Need to read Variable address.

Hello Govinda,

We don't have an immediate designated expert for this sort of topic, so please let me take some time to see if I can locate someone more familiar with DSS.

Best regards,

Omer Amir

Sure Take your time 

Hii 

I had a Query regarding the DSS Script.

Overview 

we are trying to automate DSS Script (Read or write Software Variables) from ECU Test Tool 

 ECU Test tool doesn't have direct Compatibility to automate DSS Script, so we are trying to create with LabVIEW or python interface for DSS SCRIPT

We need Two Queries Support 

1. DSS Script should run Continuously for reading and writing the software Variable. 

2 How to pass the data to DSS Script From Python or LabVIEW?

Thank You

1. DSS Script should run Continuously for reading and writing the software Variable. 

Please explain your exact use case. Are you looking to have the script continually read/write variables while the target is running?

GOVINDA Raj said:

2 How to pass the data to DSS Script From Python or LabVIEW?

I do not have any experience with LabVIEW so I cannot comment on this. But it is possible to use python with DSS:

Hii ki

1. Yes, scripting continually to read and write variables while target is running can u explain in detail? 

2. Thank We look into it. 

GOVINDA Raj said:

1. Yes, scripting continually to read and write variables while target is running can u explain in detail? 

C2000 supports real-time memory accesses by default. Hence, your DSS script can run the program asynchronously and then continue to make memory.read and memory.write calls to access memory while the target is running.

Hii KI thanks for the Confirmation

We had another Queries in jython 

1.We are trying to run the Jython Script, We can  able to set the environment variables, setting files location (ccxml,.out file) runs the scripts but while setting the Breakpoints in script, the memory address in the output is not shown positive as we expected.  i have mentioned the breakpoint script below

# Set a breakpoint

address = debugSession.symbol.getAddress("ReadNextData")

bp = debugSession.breakpoint.add(address) 

could u please clarify this script with solution? 

thanks 

GOVINDA Raj said:

# Set a breakpoint

address = debugSession.symbol.getAddress("ReadNextData")

bp = debugSession.breakpoint.add(address) 

This implementation is fine. Remember that to get the correct address for "ReadNextData", it must be in debug scope when the getAddress API is called.

Hi KI thanks for the Update

But for jython, Address is not considering as a variable to fetch the exact memory address and set breakpoint. so in that case i need to consider address as a variable can u provide jython script to set the variable. 

Hi ki we are having more Queries regarding the Jython Script 

Can we Connect a meeting Call in Teams So that also we can be able to Clarify our doubts Quickly?

You can set breakpoints on a source line or address. You can look up the address of symbols. "ReadNextData" is a function (not a variable), hence the example would be getting the address of the function start and setting a breakpoint there.

Please explain what exactly you are trying to do. Where exactly are you trying to set a breakpoint?

HII Kii 

actually we need  jython script based on breakpoints modified we tried to execute but currently not working ones, can u provide it would be much helpful

jython breakpoint code 

from java.lang import *
from java.util import *
from com.ti.debug.engine.scripting import *
from com.ti.ccstudio.scripting.environment import *

#Create our scripting environment object - which is the main entry point into any script and
#the factory for creating other Scriptable Servers and Sessions
script = ScriptingEnvironment.instance()

#Create a log file in the current directory to log script execution
script.traceBegin("BreakpointsTestLog_python.xml", "DefaultStylesheet.xsl")

#Set our TimeOut
script.setScriptTimeout(15000)

#Log everything
script.traceSetConsoleLevel(TraceLevel.ALL)
script.traceSetFileLevel(TraceLevel.ALL)

#Get the Debug Server and start a Debug Session
debugServer = script.getServer("DebugServer.1")
debugServer.setConfig("C:\\ti\\ccs1240\\ccs\\eclipse\\workspace\\LaunchpadC2000\\targetConfigs\\TMS320F28027.ccxml");
debugSession = debugServer.openSession("*","*")

debugSession.target.connect()

#Load a program
# ScriptingEnvironment has a concept of a working folder and for all of the APIs which take
#path names as arguments you can either pass a relative path or an absolute path)
debugSession.memory.loadProgram("C:\\ti\\ccs1240\\ccs\\eclipse\\workspace\\LaunchpadC2000\\Debug\\LaunchpadC2000.out")

#Set a breakpoint
address_main = debugSession.symbol.getAddress("main")
bp = debugSession.breakpoint.add(address)

# Inspect the state of the program
print("a:", debugSession.expression.evaluate("a"))

#Run if already not automatically halted at main. Should halt at first BP
if(debugSession.expression.evaluate("PC") != address):
script.traceWrite("The PC value is equal to the main value.")
else:
script.traceWrite("The PC value is not equal to the main value.")

#Run the target. Should halt at our breakpoint.
debugSession.target.run()

# Using an expression - get the current value of the PC
nPC = debugSession.expression.evaluate("PC")

#Verify we halted at the correct address.
if (nPC == address):
script.traceWrite("SUCCESS: Halted at correct location")
else:
script.traceWrite("FAIL: Expected halt at 0x" + Long.toHexString(address) + ", actually halted at 0x" + Long.toHexString(nPC))
script.traceSetConsoleLevel(TraceLevel.INFO)
script.traceWrite("TEST FAILED!")
script.traceEnd()
System.exit(1);

#All done
#debugSession.target.disconnect();
#debugSession.terminate()
#debugServer.stop()

script.traceSetConsoleLevel(TraceLevel.INFO)
script.traceWrite("TEST SUCCEEDED!")

debugSession.target.run()

#Stop logging and exit.
script.traceEnd()

Can you also give me the "LaunchpadC2000.out" executable? I will try to run the script from my end and see if I run into any issues.

Uh i cant able to update  the .out file Ki  in this chat box 

You should be able to simply drag and drop the file to the edit box.

If the issue is with privacy, you can send it via private E2E message

Hi kii 

we need to implement CCS TOOL WITH ECU Test Tool Tracetronics for automation 

can u comment and provide best possible ways  Integrated with ECU Test tool

since CCS Doesn't have Direct Compatibility with ECU Test Tool

I have no experience with the ECU Test Tool, hence I can not provide any insight on this.

Hi Thanks For the Response

we had one doubt. 

can we able to get TCP PORT NUMBER of CCS Tool Which is installed in local PC!

GOVINDA Raj said:

What is the purpose of this information?

Hii Kii 

during Debugging & writing the CCS Variable through DSS Script, .out file is not updating. 

But during the manual debugging and writing using CCS Tool .out File is updating 

kindly clarify the Doubt ASAP!

DSS Debugging and writing script attached below.

// Import the DSS packages into our namespace to save on typing
importPackage(Packages.com.ti.debug.engine.scripting)
importPackage(Packages.com.ti.ccstudio.scripting.environment)
importPackage(Packages.java.lang)

// Create our scripting environment object - which is the main entry point into any script and
// the factory for creating other Scriptable servers and Sessions
var script = ScriptingEnvironment.instance()

// Create a log file in the current directory to log script execution
script.traceBegin("BreakpointsTestLog.xml", "DefaultStylesheet.xsl")

// Set our TimeOut
script.setScriptTimeout(15000)

// Log everything
script.traceSetConsoleLevel(TraceLevel.ALL)

debugServer = script.getServer("DebugServer.1")
debugServer.setConfig("C:\\ti\\ccs1240\\ccs\\eclipse\\workspace\\LaunchpadC2000\\targetConfigs\\TMS320F28027.ccxml");
debugSession = debugServer.openSession("*","*")
debugSession.target.connect();

// Load a program
// (ScriptingEnvironment has a concept of a working folder and for all of the APIs which take
// path names as arguments you can either pass a relative path or an absolute path)
debugSession.memory.loadProgram("C:\\ti\\ccs1240\\ccs\\eclipse\\workspace\\LaunchpadC2000\\Debug\\LaunchpadC2000.out")

script.traceSetConsoleLevel(TraceLevel.INFO)
script.traceWrite("Debug session started!!!!!!")

var bp1 = debugSession.breakpoint.add('main.c',11);

debugSession.target.run()

var address = debugSession.symbol.getAddress("a")
var address2 = debugSession.symbol.getAddress("b")

script.traceSetConsoleLevel(TraceLevel.INFO)
script.traceWrite(address)
script.traceWrite(address2)
script.traceWrite("Address Readed!!!!!!")

//write data
debugSession.memory.writeData(Memory.Page.PROGRAM, address, [0x02], 16)

//write data
debugSession.memory.writeData(Memory.Page.PROGRAM, address2, [0x05], 16)

script.traceWrite("value written!!!!!!")

// All done
debugSession.target.disconnect();
debugServer.stop()

Having the *.out file will help. Can you provide this to me. You can send via private E2E message if you wish. Just zip and then drag to edit box to attach

Hii kii i have shared the Java Script in your Private Message kindly check.

one more support .

can u provide java script library packages for DSS, we need to automate with the ECU Test Tool, with these java script packages to implement library in ecu test tool can u provide this ASAP! it would be much helpful.

GOVINDA Raj said:

Hi KEE thanks for the update. 

one more Support from your side 

Can u Provide Flash Program in labview.vi. 

GOVINDA Raj said:

Sorry I don't know anything about LabView.

Hii kee Thanks for the update 

Currently i am having xds 200 JTAG Emulator and the target is TMDSEMU200-U but creating a new project using XDS 200 debug probe Target is not showing nor available in selection. I have attached the image below. Kindly reply ASAP !

"Target" would refer to the device you are working with, not the debug probe (which is "Connection")

Thank you for the outfile. I was able to run the script above. It appears to run perfectly. When I run the script ind debug mode, I can see that the variables for "a" and "b" were written to with the correct values of 2 & 5 respectively (double-click on image to full size):

Are you saying that you don't see this happen when you run you run the script?

yes, Kii while running the DSS script .out File is not updating but in manual testing .out file is updating.  

Hi Kii Thanks for the Update!

how can I set the TMDSEMU200-U target CCS Project in code Composer Studio?

GOVINDA Raj said:

DSS script .out File is not updating

What exactly does this mean? When I run your DSS script, it works perfectly from my perspective. I don't understand where there is an issue.

GOVINDA Raj said:

Under "Connection" as shown below:

Hi Kii 

when in manual Debugging the .out file its updating and we can be able to see the update .out file in Debug Folder of Workspace 

when in Debug Server Scripting (DSS) we are Executing in Command Prompt Execution is Done Successfully but the .out file is Not Updating in Debug Folder while doing DSS Execution 

kindly help to Resolve this Issue.

GOVINDA Raj said:

but the .out file is Not Updating in Debug Folder while doing DSS Execution 

Again, I don't understand what this means!

Why would the .out file update? I would just get loaded by CCS.

The DSS script is working just file. 

GOVINDA Raj said:

Perhaps a video would help explain your expectation. I want to see what you mean by "see the update .out file in the Debug Folder"

Hi KEE i have doubt 

while setting the breakpoint manually in code composer studio , can we able to find out breakpoint time (like how much time it will take to execute in ms )
