Other Parts Discussed in Thread: CONTROLSUITE, TMS320F28335

Hai,

My processor is eZdsp F28335. Working with Example_2833xDMA_xintf_to_ram example project, when built, its showing the following errors. I tried to link through

1.C:\ti\controlSUITE\libs\math\IQmath\v160\lib

C:\ti\controlSUITE\libs\math\FPUfastRTS\V100\lib

2.C:\tidcs\c28\C28x_FPU_fastRTS\V100\lib

C:\tidcs\c28\IQmath\v15a\lib

But same result..

C:\ccsv4\utils\gmake\gmake -k all
'Building target: Example_2833xDMA_xintf_to_ram.out'
'Invoking: Linker'
"C:/ccsv4/tools/compiler/c2000/bin/cl2000" -@ccsLinker.opt -o "Example_2833xDMA_xintf_to_ram.out"

Build complete for project Example_2833xDMA_xintf_to_ram

Please tell me how to link these libraries... ??

Thanq in advance,

Komali.

Hi,

1.C:\ti\controlSUITE\libs\math\IQmath\v160\lib

C:\ti\controlSUITE\libs\math\FPUfastRTS\V100\lib

The above seems to be the default one and is fine. Check these settings:

Also go through this doc:

2311.C28x_FPU_FastRTS_v10.pdf

Gautam

Thats how it is already set...

I don't think that is the problem...

Hi,

error: cannot find file "rts2800_fpu32_fast_supplement.lib"
error: cannot find file "IQmath_fpu32.lib"

Please check whether :

rts2800_fpu32_fast_supplement.lib is present or not

For me its present over here: C:\tidcs\c28\C28x_FPU_fastRTS\V100\lib

This would surely vary....

Gautam

Hi Gautam,

For me also it is present in the same location...

C:\tidcs\c28\C28x_FPU_fastRTS\V100\lib

I guess it is because it is placed in the default location when we install the CCS & other tools.

Thats it Komali, there's nothing more to do!

I downloaded the library and then read the above doc... thats it. I've been using this library since a long time for F28335. I neither experienced any errors for fastRTS nor IQMath library.

Very strange... the errors have to do with the .lib files as they're not locatable. Check with the "include" option in Project properties too. Other than these simple things there should be no other complications!

Gautam

Hello Komali!

You can try to point the library paths explicitly in File Search Path option (full path C:\.....). This can help.

Igor

Hai Igor,

I tried giving Full Search Path in the properties of C2000 Linker option.

But the error showing is:

'Building target: Example_2833xDMA_xintf_to_ram.out'
'Invoking: Linker'
"C:/ccsv4/tools/compiler/c2000/bin/cl2000" -@ccsLinker.opt -o "Example_2833xDMA_xintf_to_ram.out"
fatal error: cannot open file "C:\\tidcs\\c28\\IQmath\\v15a\\lib": Permission
denied

Any suggestions..?

Hai Gautam,

I tried everything possible to add the libraries..

include from ccs libraries, include from control suite, file search path option.

Thankyou for the document, it is a very useful one..

Hi,

Interested in setting up a Fresh copy of CCS v5.4?

Regards,

Gautam

Intellectual 515 points

ya..but not sure about few things..

It works with TMS320f28335 & ezDSP F28335 without any problems..?

It needs license..?

It is as simple as upgrading or Should be installed separately..?

Please tell me.

Regards,

Komali.

You can try installing a new copy in parallel at a different location. License is "Free" as you're using a C2000 based controller.

Gautam

Hi Lakshmi!

Perhaps you didn't understand me exactly. I mean full path in box "Include library file or command file as input" (upper box in File Search Path option) . For example C:\\tidcs\\c28\\IQmath\\v15a\\lib\IQmath_fpu32.lib.

Igor

Hai Gautam,

I've installed CCSv5. I will try to run the target and i'll be back tomorrow.

Thankyou for your suggestions..

Hello Gautam,

When connected to eZdsp F28335 it needs license?

dialog box

License cannot be acquired.

No valid license for Code Composer Studio could be found.

To be able to use any of JTAG debugging features of CCS you will need a license

That was the dialog box...its asking license.

What should I do?

Thank you in advance,

Komali.

No problem. Do revert.

I am creating a CCS project with command line scripts,
and would like to include the rts2800_fpu32_fast_supplement.lib.

When creating a project with the rts2800_fpu32_fast_supplement.lib, if I don't specify
the rts2800_fpu32_fast_supplement.lib as the runtime support library, -ccs.rts, I can't
get it as the 1st choice for the include library for the linker.
It actually seems like I have to choose it as the -ccs.rts option, then go into
the project options and change the rts to libc.a. If I leave libc.a as the -ccs.rts
and then change the priority of the rts2800_fpu32_fast_supplement.lib in the linker
search path, it still doesn't link correctly even though I get no build errors.

Can anyone tell me the command line options I need for generating a CCSv5 project with the
rts2800_fpu32_fast_supplement.lib.

I tried --disable_auto_rts linker option, it seemed to have no effect.

CCSv5 version is 5.4.0.00091. ccs.cgtVersion is '6.1.3'

Thanks, Dave
