GPP side of DSLINK apps in CCStudio 3.3?

I don't know much about DSPLINK but I have seen the linker error before. You have a memory model mismatch between various object files.

Explained in more detail here:

Ki-Soo,

Thank you for taking the time to answer my question. However, I could still not fix the problem. None of the libraries available in the C:\CCStudio_v3.3\C6000\cgtools\lib\ folder are compatible types and it says "liba.c could not resolve library".

Here are more details of my project:

I'm using the OMAPL137 EVM and trying to compile the GPP side of code for DSPLINK applications in CCStudio v3.3 (samples/loop.c). 

Compiler options I'm using: -g -pdsw225 -o2 -fr"$(Proj_dir)\Debug" -i"D:\angstrom\arm\lib\gcc\arm-angstrom-linux-gnueabi\4.3.3\include" -i"D:\linux-03.20.00.14\include" -i"D:\dsplink_mod\gpp\inc" -i"D:\dsplink_mod\gpp\inc\usr" -i"D:\dsplink_mod\gpp\inc\sys\Linux" -i"D:\dsplink_mod\gpp\inc\sys\Linux\2.6.18" -i"D:\dsplink_mod\gpp\src\samples\loop" -i"D:\dsplink_mod\gpp\src\samples\loop\Linux" -i"D:\dsplink_mod\gpp\src\samples\loop\Linux\2.6.18" -i"D:\angstrom\arm\arm-angstrom-linux-gnueabi\usr\include" -i"D:\dsplink_mod\gpp\BUILD\INCLUDE\USER" -d"_DEBUG" -d"OS_LINUX" -d"MAX_DSPS=1" -d"MAX_PROCESSORS=2" -d"ID_GPP=1" -d"OMAPL1XX" -d"PROC_COMPONENT" -d"POOL_COMPONENT" -d"NOTIFY_COMPONENT" -d"MPCS_COMPONENT" -d"RINGIO_COMPONENT" -d"MPLIST_COMPONENT" -d"MSGQ_COMPONENT" -d"MSGQ_ZCPY_LINK" -d"CHNL_COMPONENT" -d"CHNL_ZCPY_LINK" -d"ZCPY_LINK" -d"KFILE_DEFAULT" -d"DA8XXGEM" -d"DA8XXGEM_PHYINTERFACE=SHMEM_INTERFACE" -d"GPP_SWI_MODE" -d"_REENTRANT" -d"VERIFY_DATA" -d"DDSP_DEBUG" -me -mv5e --verbose -c

The project consists of loop.c from the \dsplink\gpp\src\samples\loop and the linker cmd file.

Error I get:

We are further investigating the first issue.

Regarding your second issue...

Now I'm confused. You are using the ARM tools to build but your project is referencing C6000 libraries. I think you are building for ARM, judging from your build options. And I see it references files from the gcc build tools. What kind of project are you building?

Ok I see the problem. You are building an ARM project but you are including the C6000 run-time library. You need to grab a library from C:\CCStudio_v3.3\tms470\cgtools\lib

Bindu,

After consulting with some other experts, my initial assumption was incorrect. It is not related to memory models. You probably manually added that library to try to address it when you did not need to.

I'm afraid I cannot help much because I am simply not familiar with building DSPLINK. I will move your query into the BIOS forum where the folks there are more familiar with it.

Thanks

Thanks again Ki-Soo.

Here are the updated details. The compilation error that occurs when I don't provide any options for the linker library (flag -l). I repeat, I only have one source file (dsplink\gpp\src\samples\loop\loop.c) in the project, since the SOURCES file in the same folder contained only this file too:

What I'm trying to do, it avoid using the make files that come with /dsplink, and instead use CCStudio v3.3 to achieve the same goal -- produce the DSP side .out file and the GPP executable. I have been successful in the former, but miserably failing at the latter.

Bindu

Thank you Arnie, maybe I'll try compiling the GPP-side app as just another C/C++ project, where I will have more control over what compiler and linker its using.
