CCS/TMS320F28069M: CLA error Header file <string.h> not supported by CLA compiler

Tool/software: Code Composer Studio

Hi,

I am trying to make a V-f motor control scheme in Simulink (R2017b ) embedded coder with CCS Version: 7.4.0 toolchain . The build process in simulink was returning these errors :

cla_task.cla", line 76: error: identifier "V_F_control_CLA_P" is undefined

"cla_task.cla", line 76: error: identifier "V_F_control_CLA_DWork" is undefined

So I import the project in CCS and open cla_task.cla file. The above mentioned objects are defined in V_F_control_CLA.h file and it is missing in cla_task.cla. I add the include to the file and rebuild the project:

Now the number of errors increase , one due to the below definition in string.h and other long long definitions in "math.h" is nonstandard.

#if defined(__TMS320C28XX_CLA__)
#error "Header file <string.h> not supported by CLA compiler"
#endif

As these are standard libraries, I am not sure how to make any modifications to these libraries . Does anyone know any work around to get the code running without affecting the functionality?

Thanks in advance!!

I will forward your query to Matlab / Simulink support, you are better off these MATLAB related queries to them.

Hi Arun,

Did you try the shipping example? Does it work?

Note: There are a number of limitations to using the CLA, both from MathWorks tools and TI Compiler. You need to look at all of these limitations and make sure you aren't hitting one.

TI CLA info: http://processors.wiki.ti.com/index.php/C2000_CLA_C_Compiler

In the past, I have run the shipping demo and gotten it to work with the CLA. I think you should start with that; once that works, then migrate to working on your model.

Cheers,

-Brian

Hi Brian,

I will try to do that. The problem is none of the example models use division or memory operations. I will get back as soon as I test something made from a modified example model.

Thanks and Cheers,
Arun

math.h and string.h are not supported on the CLA. If you need some CLA functions, you can see the CLA math library in C2000Ware in the /libraries folder.

Hope this helps!
