RTSC Config Winodow not functioning properly?

Mike,

I have been seeing the same myself this morning.  Working with the RTSC team to see what is going on.

John

I teporarily got around it by manually entering TMS320C5515 in both fields.

While you're at it, have them check into the following statement in section 1.4 on page 9.

"To add a RTSC configuration file to an existing project, choose File > New > RTSC Configuration File. Then click Next. Type a name for the file and click Finish."

...which produces the following error

Is that the same name as your main project?  You can't have 2 projects with the same name.  Try typing _config at the end of the name so that it is different from your other project.

John

Ahhh...yes. You are correct. That was the problem.

Thanks,

MikeH

Well.....this workaround didn't get me very far.

Severity and Description Path Resource Location Creation Time Id
Can't find platform package TMS320C5515  hello_configuration line 0 1279913493782 380

Any news from the experts?

The closest one I see is: ezdsp5505

To create one that matches exactly would mean running the platform wizard which is where I am stuck.

John

Mike,

In that dialog in your screen capture where you are selecting the platform type: "ti.targets.C55_large" in the RTSC target box.  That will enable the platform drop down to show a list of compatible platforms.

John

Mike --

Note that we do not support the 55x device with BIOS 6.x.   The list of devices supported by BIOS 6.x is specified int the release notes.  You are on the wrong track.

You need to use BIOS 5.41 for 55x.

Regards,
-Karl-

Arrrgghh! Thanks for the heads up.

Does this mean that C55XX will never be supported in BIOS 6.x? Or is it just behind in development?

MikeH

Karl,

Can you point me to a primer or walk-thru on using BIOS 5.x with the C55x devices?

Thx

MikeH

Hi Mike,

Karl has asked me to help out.  Can you please tell me which version of CCSv4 you are using as well as which version of BIOS 5.41 you have installed?  Which 55xx device are you using?: I think I can help you get up and running an example rather quickly once I know this information.

Thanks,

-Jon

Jon,

Config below

Device is C5515 ezdsp USB Stick

Thx

MikeH

Mike,

You can create a new c55xx project as follows.

Start CCSv4.0

File--> New--> CSS project

Give the project a name as you create it, i.e., stairstep_c5515

Select project type of c5500

When you get to the project settings window pane, select TMS320C5515 for the device variant and then select the radio button at the bottom for Target Content to "Use DSP/BIOS v5.xx

Click "finish"

There should now be a new project created in CCS.  Create the .c and .tcf files below for 5515. Right click on the "stairstep_c5515" project and select "add files to project". Add the two newly created files stairstep.c and staistep.tcf.  Build the project.   Let me know if you need help configuring your target and running the example.  You should be able to open the debugger for your 5515 board and open the Tools--> RTA -->Printf Logs and CPU Load to see the example run.

Jon,

I appear to have a path problem with the .tcf file (see below). FYI, when intially creating the .tcf file (before inserting your text), I used the new ti.platforms.ezdsp5515 platform file that I created from the evm5505 file. I then erased all of the existing text and added yours to the new file.

=======================================

'js: "C:/Program Files/TI3/xdctools_3_20_01_51/include/utils.tci", line 946: Error: Can't load platform definition 'ti.platforms.evm5515': Error: Can't load 'ti/bios/config/bios_5515.tci': Error: Can't find import file: 'ti/bios/config/bios_5515.tci' (not found along 'C:\Program Files\TI3\xdctools_3_20_01_51\packages\ti\platforms\evm5515/;;C:/Documents and Settings/Mike/My Documents/TI Workspaces/test/stairstep_c5515;C:/Program Files/TI3/bios_5_41_02_14/packages;C:/Program Files/TI3/xdctools_3_20_01_51/include;C:/Program Files/TI3/xdctools_3_20_01_51/packages')

Correct any script errors in C:/Documents and Settings/Mike/My Documents/TI Workspaces/test/stairstep_c5515/.gconf/stairstep_c5515/stairstep_c5515.tcf

using the Configuration Tool or a text editor, if necessary.

TConf initialization arguments:

-e environment['config.importPath']='C:/Documents and Settings/Mike/My Documents/TI Workspaces/test/stairstep_c5515;C:/Program Files/TI3/bios_5_41_02_14/packages' -e environment['config.scriptName']='stairstep_c5515.tcf'"

Hi Mike,

Check the build properties for the project and make sure you are pointing to BIOS 5.41.04.18 in the project.  From the errors, it is using BIOS 5.41.02.14 which does not have support for 5515.   I think if you get that straightened out it should build.

-Jon

Jon,

Yes, that was the problem.

However, now I am getting this.

"could not open source file "stairstepcfg.h" stairstep_c5515 stairstep.c line 29 1280512550718 421"

Where should staristpcfg.h come from?

MikeH

Hi Mike,

This file is auto-generated.  In CCSv4 open "Windows --> Preferences --> CCS"  Click on RTSC and make sure that the correct version of BIOS 5.41.04.18 is selected.  Make sure that the XDCtools version is also set to the correct version here.

-Jon

Jon,

I realize the file is auto-generated. What should I do to correct the compile error? I have verified that the BIOS is the correct release and the XDAIS is set to 6.25.01.08 (see below). The compile error remains.

Hi Mike,

I've just re-created the same setup with same versions and I'm building  the same stairstep example for 5515 without the error you are seeing.  Only difference I see is that I have the XDCtools set to XDCtools 3.20.01.51.  In your screen shot there is no XDCtools selected "XDCtools version:" box right below RTSC support line.  It should not matter but could you set the XDCtools version, try a "project clean" and then try "rebuild project" so it rebuilds the everything.  If that does not work can you post the whole output from the console window so I can see the entire compile message with error.

Thanks,

-Jon

Jon,

1. Set XDCtools to 3.20.01.51 (see screenshot)

2. Set Code Generation Tools to TI V4.3.6

3. Cleaned and rebuilt project.

Same problem exists ("cannot find stairstep.h")

4. Changed the include line to read "#include stairstep_c5515cfg.h" instead of "#include stairstepcfg.h".

The project builds but give the following error.

"file "C:/Program Files/TI3/bios_5_41_04_18/packages/ti/bios/lib/bios.a55L<fxn.o55L>" specifies large memory model, which is not compatible with huge memory model specified in a previous file or on the command line  stairstep_c5515 line 0 1280685650765 443"

Below is the contents of the console window after renaming stairstipcfg.h to stairstep_c5515cfg.h and building the project.

FYI. Just changed the Runtime Model in the projcet to Large (was Huge) and the project builds, links, and runs. Hmmm...??

Now, can you point me to a tutorial on actually *using* the RTSC tools?

thx

MikeH

Hi Mike,

There are some tutorials posted here that should be helpful.   Let me know if you are looking for something more specific.

http://rtsc.eclipse.org/docs-tip/Using_RTSC_with_CCStudio_v4

-Jon

Jon,

All of the information in the link you sent describe the basics of setting up an RTSC project. Now that we have accomplished that, how do I use the RTSC tools to look at the results of the captured data? What tools are available (ie ROV, RTA, etc) and how do I use them to analyze the cpu load, etc? I am looking for a basic example walk-thru of using the RTSC tools to analyze the performance of the cpu while running my application.

A great example is, what do I now do with stairstep?

thx

MIkeH

Jon,

OK. I think I get it now. Let's close this thread and start a new one.

Thanks!

MikeH

Mike,

There is a description  of the example and what it does in the comment at the top of  stairstep.c file. 

You can open the the different RTA tools to see the how the stairstep example is running and what values are returned.  The previous link I shared has descriptions on how to use RTA and ROV when running an application.  

http://rtsc.eclipse.org/docs-tip/Real-Time_Analysis_Tools

http://rtsc.eclipse.org/docs-tip/Runtime_Object_Viewer

If you load and run the stairstep example with the RTA CPU load graph window open you should see a line with a step every 25% cpu load until it reaches 99% where it will drop back to 0% and repeat itself.  This should show you that your example is configured and running at the correct CPU value.
