how to make code generation with OMAP-L138 Experimenter Kit, CCSv5.5 and MATLAB SIMULINK

Hi,

Thanks for your post.

In general, TI would not support MATLAB simulink model code generation but after seeing your compilation errors, I have few suggestions below:

1. Could you please locate the path of the inclue file "dlfcn.h" which is defined in the source file "./HostLib_Audio.c" and kindly check whether the corresponding include path is added in the project properties. Also ensure whether the same include file "dlfcn.h" is physically available in the specified path, so that, you could resolve this undefined include file error and fix the compilation of source "./HostLib_Audio.c"

2. One more observation, when you cross through the checkEnvSetup('ccsv5', 'omapl138evm'), there are conflicts thrown and it is better to fix the same as below:

A. DSPBIOS version differs from the one used for software validation, so, kindly use the required version below:

  Required version: 5.33.05 to 5.41.11.38

  Required for    : Code generation

  Your Version    : 5.42.01.09

B.  Please set the below environment variable which is required for code generation

  ### "NDK_EVMC6748_INSTALLDIR"

C The version found for "C674x DSP/BIOS PSP Drivers" differs from the one used for our software validation. Kindly use the required version below:

  Required version: 1.30.00.05

  Required for    : Code generation / device drivers

  Your Version    : 1.30.01

Kindly use the above recommendation and try to compile the source file "./HostLib_Audio.c"

Thanks & regards,

Thank you very much, Sivaraj!

At first, I have fixed all the settings in the Matlab Command window so as the program required.

Secondly, I checked again, whether the file "dlfcn.h" is anywhere to find. But I can't find it, wether in the by Matlab created folder, nor in any projects of the PC. This file would be needed as an include file for the source file "./HostLib_Audio.c". I think, Matlab should make this file by himself und use it later at code generation with CCS.

Have you any idea, Sivaraj? Or anyone else can kindly tell me, how to solve it?

Hi Zhirong, hi Titus,

thank you for providing a detailed description of the steps that you have taken.

Is it really need to perform both steps 1 and 2, i.e. first call checkEnvSetup(..., 'setup') and then also the xmakefilesetup tool? Doesn't it do the same?

I have the problem that checkEnvSetup skips "XDC Tools (eXpress DSP Components)" and so it does not recognize my version. However there is a folder C:\ti\xdctools_3_25_03_72. Is there a method to set it manually?

xmakefilesetup does list the correct folder for XDC Tools Installation correctly.

I tried two (modified/cloned) configurations for OMAP-L138 EVM "ticcs_c6000_dspbios_ccsv5" and  "ticcs_c6000_ccsv5". As I am using the OMAP I guess it needs DSP/BIOS because there is no choice under "Target Hardware Resources" to select "None" for OS (the dropdown menu is grayed out, red box in the screenshot):

A) When using "ticcs_c6000_dspbios_ccsv5":

When performing the build I get the following error messages:

So I think again that this is related to the settings done before.

Edit: What I really think is strange: the tconf.exe tool indeed cannot be found in the XDCtools directory (C:/ti/xdctools_3_25_03_72) but in the XDCtools subdirectory of DSP/BIOS folder (C:\ti\bios_5_42_01_09\xdctools).

Edit 2: When I manually try to execute the tconf tool from the subfolder in the DSP/BIOS folder I get the following error message(s):

C:\ti\bios_5_42_01_09\xdctools\tconf -b -Dconfig.importPath="C:/ti/bios_5_42_01_09/packages" ./mysumdiff.tcf

C:\ti\bios_5_42_01_09\xdctools\tconf: can't create session manager: create of JVM failed

Additionally an error message pop-up opens which tells me that MSVCR71.dll is missing.

B) When using "ticcs_c6000_ccsv5" (w/o DSP/BIOS):

I guess it is missing the <modelname>cfg.h file as this is required by DSP/BIOS or created by the DSP/BIOS Tconf tool as I have read elsewhere (here: http://de.mathworks.com/matlabcentral/newsreader/view_thread/277160#767237.

Any help will be appreciated.

Thanks,
Matthias

Hello Zhirong,

thank you for your help! I took the same version of XDCTools as you and it seems to work.

Another important step was indeed to set the correct Execute Tool & arguments to load the executable directly on the board without having to do it from the CCS IDE. But this is where I got stuck.

Note: Did you get your Execute Tool really running with "C:\Program Files\MATLAB\R2014b\...". I could not manage to do it with file paths that include spaces. Even double quotes did not help and so I had to work around using shortnames (DOS paths limited to 8 caracters for each level), e.g. ""C:\Progra~1\MATLAB\R2...". I had another space in the path of the ccxml file.

May I ask which ccxml file you are using? I think that I am using the same board as you. Mine references two GEL files, one for the ARM core, one for the DSP core.

Did you have difficulties with waking up the DSP from within the ARM code? Are the GEL files also executed when using the DSS approach?

I get the following error message again [ https://e2e.ti.com/support/dsp/tms320c6000_high_performance_dsps/f/115/p/72371/1823780#1823780 ] - from the command line:

*** Connecting to target...

SEVERE: C674X_0: Error connecting to the target: (Error -1180 @ 0x0) Device is held in reset. Take the device out of reset, and retry the operation. (Emulation package 5.1.232.0)

This might be related to the relative path to the GEL file instead of absolute path, but I'll have to double check it.

Edit: I wonder how this is done... in the CCS IDE if I click on ARM9_0 or C674x_0 I can see the initialization script paths (GEL file paths) in the Advanced View. But when I have a look at the source code, no .gel file extension can be found. So how can I tell DSS to use them? Or how is it done in CCS IDE?

Edit 2: I will also try to figure out what the differences and similarities between TI's loadti DSS example is and Mathworks' runProgram.js. But if somebody can already tell I'd be happy to see a summary on that.

Edit 3 [related to Edit 2]: I have modified Matlab's runProgram.js DSS script to work with OMAP-L138 SoC. It requires some understanding but is then straight forward to be done, there is also a helpful section in the TI wiki: http://processors.wiki.ti.com/index.php/Debug_Server_Scripting#Multiple_Debug_Sessions_for_Multi-core_Debug . Both TI's loadti DSS example nd Mathworks' runProgram.js (of course) use the same commands but Mathworks' version is smaller (probably less complex) and allows a better and fast overview.

Thank you for your help again!
