taking advantage of CLA using TI embedded coder support package

Other Parts Discussed in Thread: TMS320F28035

Hi. I am trying to take advantage of CLA (control law accelerator) in TI embedded coder support package. I already generated the C code for CCS3.3 using MATLAB r2014a without CLA. But In need more frequency from DSP. so there is no choice left for me but to take advantage of CLA. when I generate the code using the CLA block available in TI embedded coder support package the code compiles with the following error in CCS V3.3:

""""undefined symbols

---------

Cla1prog_start C:\\Documents and settings\....\MATLAB\\CLA3ticcs\\customMW\\CLA3.obj

RamfuncsLoadEnd C:\\Documents and settings\....\MATLAB\\CLA3ticcs\\customMW\\CLA3.obj

RamfuncsLoadStart C:\\Documents andsettings\....\MATLAB\\CLA3ticcs\\customMW\\CLA3.obj

error: unresolved symbols remain error:

errors encountered during linking, "CLA.out" not built >>compilation failure""""

and the MATLAB error command is:

""""The call to idelink_ert_make_rtw_hook, during the exit hook generated the following error: Error while building the project The build process will terminate as a result .error while building the project . An exeption occured while performing this operation""""

by the way, my system target file in Matlab is: idelink_ert.tlc and my Microcontroller is TMS320F28035. Id be appreciated if someone helped me. thanks in millions Navid

Hi Navid,

The CLA block for TI C2000 is a demo feature and not supported with idelink_ert.tlc. It is supported with ert.tlc only.

Here is an example which explains CLA block usage with ert.tlc:

Hi Brian
Now I am working under ert.tlc and I am trying to generate my code with xds100v2 texas emulator. while generating I confront an error which ends with the following error command:
" failed to generate all binary outputs"
in case for information my OS is windows XP which I have generated the code with under idelink_ert.tlc using ccs3.3 and a xds510. Now I have a xds100v2 and trying to generate code with CCS5 under ert.tlc so that I can take advantge of CLA in TMS320f28035.
Can you help me with this?
I would be appreciated if you did...
regards
Navid

Navid,

Did you get the Example to work?

Dear Brian,
based on the following link by mathworks I worked my way out and built my .out code with XDS100v2 to complie by CCSv5.

www.mathworks.com/.../25472-ccs-5-1-integration-when-and-how

but the problem is that this configuration is under idelink_ert.tlc
when I change my system target file to ert.tlc the the build process ends with the following error command :

"error encountered while executing PostCodeGenCommand for model 'c28035blink_cla': The path
'C:\ti\ccsv6\tools\compiler\c2000_6.2.7\..\..\..\ccs_base\scripting does not exist
caused by
The path 'C:\ti\ccsv6\tools\compiler\c2000_6.2.7\..\..\..\ccs_base\scripting does not exist.

And you answer: Yes I did, i used the 'c28035blink_cla' Matlab example for CLA configuration purpose, and as you know this configuration is under ert.tlc too.
so this again ended with the same error command:

"error encountered while executing PostCodeGenCommand for model 'c28035blink_cla': The path
'C:\ti\ccsv6\tools\compiler\c2000_6.2.7\..\..\..\ccs_base\scripting does not exist
caused by
The path 'C:\ti\ccsv6\tools\compiler\c2000_6.2.7\..\..\..\ccs_base\scripting does not exist.

what do I do Brian?

Navid,

The error message tells me that it is trying to locate CCSv6 compilers, not CCSv5. Type targetupdater at the MATLAB command prompt - and re-do the configuration, but select for CCSv5.

Brian,

To make sure I did reconfigure it for ccsv5.
but again the same error command appears... :-(
Do you have any other ideas?
thanks man.

Hi Navid,

Please contact MathWorks Technical Support for additional assistance.

Thanks,

Brian.
I did contact Mathworks Technical support, but no reply I could find. here is the link:

www.mathworks.com/.../261951-how-can-i-get-advantage-of-cla-control-law-accelerator-for-texas-c2000-tms320f28035-dsp

To make sure I reinstalled Matlab and got the support package again.
now while trying to generate the code for MATLAB example for CLA I confront this error message:

"failed to generate all binary outputs"

I think this might be caused due to the lack of prerequisite software or something like this.
because I have seen this error message before.
i'd really be appreciated if you told me about this...

Navid,

Direct message me your help ticket #; I can investigate from my side. I still believe you have a configuration issue, so you will likely need to send your model to tech support for them to have a look at it. I

Thanks for your support.
I look forward to that.
How do I direct message you?
I sent a friendship reqquest...
Is that what I should do from my side?
