CCS4 and CSL - can't link

I got it to work finally. I installed the CSL in the same directory (D:\Texas Instruments) as the CCSL and copied the files into my workspace. The only thing I had to do for my own project is to tell the compiler where the include files are. Voilá.

Thank you :)

Great news, Marc.

Let us know if we can help further.

Best Regards,
Mark

Sure. As I said at another place: This forum is a great help. I think I will ask something when I got to the SPI point. We'll see.

Okay it's me again. I think I have still some error inside the setup for the linker.

Here's a screenshot of the settings

I am prett sure that there's something missing.

The error I get is

warning: creating output section ".cio" without a SECTIONS specification
warning: creating output section ".const" without a SECTIONS specification
warning: creating ".sysmem" section with default size of 0x7d0; use the -heap
   option to change the default size

 undefined       first referenced
  symbol             in file    
 ---------       ----------------
 _GPIO_configBit ./main.obj     
 _GPIO_open      ./main.obj     
 _GPIO_reset     ./main.obj     
 _GPIO_write     ./main.obj     

error: unresolved symbols remain
error: errors encountered during linking; "hello_world.out" not built

I'm a bit confused 'cause when I write like config. and press strg+space he knows what's inside the object. So he included the .h correct. I hope someone can help me with that again. I guess it's all about setup right now.

I installed CCS and CSL in the same directory (D:\Texas Instruments\).

Cheers

Edit:I now added every setting which is made in the GPIO_IN example given by the CSL library. Doesn't work...

Edit: I now set this page

I read those informations somewhere in this forum. Result is that the warnings disapeared, but I still got the unresolved symbols. (I hope it is easyer then to implement the eZdsp lib :D )

Cheers

Hi Marc,

If you are still receiving the below warning, then you are not properly including the CSL library in your linker settings.

 _GPIO_configBit ./main.obj

In your C5500 Linker File Search Path window, make sure you are including the CSL library: cslVC5505.lib.

It is located under <INSTALL PATH>\c55xx_csl\ccs_v4.0_examples\cslVC5505\Debug.

You can either add this path to library search path, or copy the library file into your project path.

It looks like you have properly included "csl_gpio.h" or else you would be getting "error: identifier "CSL_GpioObj" is undefined" messages

Don't forget to read the Installation Guide (Page 8 of 30) and Building and Running the CCS v4 Projects (Page 12 of 30) of the C55XCSL-LOWPOWER-2.10.00.00_Release_Notes_20100813.pdf document.

It shows you how to setup your CCS workspace so that after importing the CSL examples, the library includes and linking paths build without issues. It also tells you how how to modify csl_general.h to support your platform (VC5505 or C5515).

Hope this helps,
Mark

Hey

Thank you. Well, I found the file before I got your answer. I had a look on it. The result is still the same

For me it looks like everythings just right. I also changed the values inside the general.h

I know that I look like a noob but I just didn't had such problems with a IDE ...

Edit: Okay I now deleted the whole workspace. I then imported every CSL example project into my workspace without copying it. Then I build every project. Result: CSL_USB_MSC_fullSpeedExample_Out has also unresolved symbols and some projects have warnings concerning the code.

So I think there's something totaly wrong. But could it be that the symbols for the CSL_USB_MSC_fullSpeedExample_Out are not resolved because I changed the csl_general.h into the c5515 device?

Oh man, I don't know. I look like a noob and time is running out :/

Marc, 

When you see -i"" in the console, it means that the linker was not able to parse your provided library search path. It looks like your RTDX_LIB_DIR and BIOS_LIB_DIR macros are not configured - they will be configured if you select which version of BIOS to use during the new project wizard.

Check out the Macros tab in the Project Configuration window to see the definitions of these macros. Macros are basically like environment variables. 

The linker is also probably not happy with the " + $[{C5500_CSL_CG_ROOT}\lib" that comes after RTDX_LIB_DIR macro. 

See the problem in this excerpt of your console output: -i"D:/Texas Instruments/ccsv4/tools/compiler/c5500/include" -i"" -i"" -i"D:/CC_Workspace/cslVC5505" -i"D:/CC_Workspace/hello_world" 

Fortunately, your project probably does not need anything from these search paths, but the point is that there is valuable information in the console output. 

--- 

The quick fix to get you up and running is to place these two attached library files into your ${PROJECT_ROOT} directory (D:/CC_Workspace/hello_world in your case) 

DSPLIB compiled for the Huge Memory Model: 4214.55hdsp.lib
(Rename to "55hdsp.lib") 

CSL compiled for the Huge Memory Model: 3683.cslVC5505h.lib
(Rename to "cslVC5505h.lib") 

Then make your C5500 Linker File Search Path look like mine with the file names ("cslVC5505h.lib", "55hdsp.lib", & "rts55h.lib") in the top field and the search paths in the bottom field (${PROJECT_ROOT} is already in your project settings).

Let me know how it works.

Regards,
Mark

Hey

Thank you. This is how I think that a compiler/linker has to be setup: Straightforward. Thank you. That helped so far.

But I still got three warnings:

I have the same code but I put a new project around it.

Hey

I have to push it sorry

I still got the warning

<Linking>
warning: creating output section ".cio" without a SECTIONS specification
warning: creating output section ".const" without a SECTIONS specification
warning: creating ".sysmem" section with default size of 0x7d0; use the -heap
   option to change the default size

I looked in the datasheets but there is nothing about the heap size.  Also I dunno what the two others are meaning. I hope someone can help me to configure my project, if CSL is running then I shouldn't have any other problems :)

Cheers

Edit: Found the file VC5505.cmd, included the file and everything is all set now. Gonna start :) I hope the heap size -heap       0x3F80 isn't too small
