CCS 4.1 Linking Problem

mak875

I wanted to create a single project based off of the provided examples that does not link other depended files. I have been able to compile the program, but when the linker is invoked I get this error on the console output:

undefined first referenced

symbol in file

--------- ----------------

_AdcRegs ./DSP2833x_Adc.obj

_CpuTimer0Regs ./DSP2833x_CpuTimers.obj

_CpuTimer1Regs ./DSP2833x_CpuTimers.obj

_CpuTimer2Regs ./DSP2833x_CpuTimers.obj

_CsmPwl ./DSP2833x_SysCtrl.obj

_PieVectTable ./DSP2833x_PieVect.obj

_SysCtrlRegs ./DSP2833x_SysCtrl.obj

_XintfRegs ./DSP2833x_Xintf.obj

error: unresolved symbols remain

The error are like this:

unresolved symbol _AdcRegs, first referenced in ./DSP2833x_Adc.obj Skel_Proj line 0 1278612764996 541

Any thoughts to why this is happening is much appreciated!

Did you ever figure this out? I ran into the same thing. I wanted to take a working example application and create a new workspace and use the code from the example as a starting point for my application. My project also compiles but fails to link with the same error you have:

error: unresolved symbols remain

I am using the Stellaris EKS-LM3S9B92 and the latest code composer studio Version: 4.1.2.00027.

Andy,

I only used files from the example project in the sprc624 projects. Where are these objects defined in that project. I'm looking for an example to reference.

@mak875:

It looks like you forgot to link the definition file for the memory mapped registers (defined as global variables) to your project. In CCS4.1: Right click at your project and select "Link Files to Project" , browse for "C:\tidcs\c28\DSP280x\v130\DSP280x_headers\source" and link. "DSP280x_GlobalVariableDefs.c". Note: My example is for the TMS320F2801x device, for others, such as F28035 or 28335, the path to "c:\tidcs" is different, also the file name "DSP28????_GloblaVariableDefs.c".

Frank, thanks! That was the problem I was having. I also needed to add the *.cmd file in the C:\tidcs\c28\DSP2833x\v131\DSP2833x_headers\cmd directory.
