Part Number: TMS320F28030

Tool/software: Code Composer Studio

Hi,

my customer is using DSS for debugging on TMS320F28030 and CCS Ver 7.2.0.

They would like to read and write data by referring to the address of the F28030.

They use memory.readData() to read and write data.

But they got below error message.

Java class "com.ti.debug.engine.scripting.Memory" has no public instance field or method named "readData".

Could you tell us why this error message is shown?

And, should they use other API?

Best Regards,

Ohhashi-san,

Can you provide how the customer is making the call? I'm looking for the line of code. If they can share their script, that it even better.

Thank you

Ohhashi-san,

Thank you for the file. When passing in the address as a hexadecimal value, the preceding '0x' is needed in front of the address to specify that it is a hexadecimal value:

var result = debugSession.memory.readData(0,0x00009a02,8);

Have the customer try that.

Thank you

Hi Ki-san,

Thank you for your reply.

They tried it but they got same error message.

var result = debugSession.memory.readData(0,0x00009a02,8);

Is there any other possible cause?

Ohhashi-san,

Can the customer provide the log.xml file?

Also, how is the customer running the script? Are calling the dss.bat file in C:\ti\ccsv7\ccs_base\scripting\bin?

Thank you

Below is log file. I would appreciate it if you would check the log.

Yes. They run dss.bat and then run the script.

Ohhashi-san,

Thank you for the document. The log is smaller than I expected. The last entry in the log is:

2019-12-09T09:52:24 1575852744542 53 com.ti.debug.engine.scripting.DebugServer FINER com.ti.debug.engine.scripting.DebugServer openSession 1 RETURN Texas Instruments XDS110 USB Debug Probe_0/C28xx

This entry corresponds the openSession(.*) call. There should be more information, especially if they generated a verbose log as seen in the example script you attached earlier. Can you confirm that this is the full verbose log? It looks more like the console output than the information generated in the log xml file. Can the customer provide the actual generated xml file in: "C:/workspace_CCSv7/lab1/log.xml"?

Thank you

Hi Ki-san,

Yes. The log.xml is in C:/workspace_CCSv7/lab1/log.xml.

They retried to get the log.xml.

I would appreciate it if you would check it.

Ohhashi-san,

The file does not have the content I was looking for.

Please see the attached zip file. It contains the script (code.txt) which was modified to run in my environment - otherwise has the same functionality. I ran it successfully. It generated a log.xml file which has the complete information. You can open it in a browser to see the detailed log.

I would like the same exact log.xml file from the customer. Not a word doc which has a copy and paste of the log. I would like the actual generated log.xml file like I provided in the attached zip file.

Ki-san,

Thank you for sending files. These files are very helpful for us. The customer found that they use "Memory" instead of "memory" in their script. They corrected the spell and then they could run the script correctly.

Thank you for your help. We really appreciate it.

Best Regards,

M.Ohhashi
