TDA4VM: Unresolved symbol when integrating mcal driver

Your question has been initially assigned to Doredla

To be more specific with my problem, I want to integrate the gpt library into the sciserver_testapp application. I have modified the makefile in this directory: /ti-processor-sdk-rtos-j721e-evm-09_02_00_05/pdk_jacinto_09_02_00_30/packages/ti/drv/sciclient/examples/sciserver_testapp
with the following lines:

LDIRS  += $(MCUSW_PATH)/binary/mcal/Gpt/lib/$(SOC)/mcu1_0/$(BUILD_PROFILE)
ADDITIONAL_STATIC_LIBS += gpt.aer5f

Building the sciserver_testapp the following undefined symbol causes error:

 Gpt_EnableNotification                 /home/$(USER)/ti/ti-processor-sdk-rtos-j721e-evm-09_02_00_05/pdk_jacinto_09_02_00_30/packages/ti/binary/sciserver_testapp_freertos/obj/j721e/mcu1_0/debug/Gpt/source/Gpt_Startup.oer5f

However the gpt.aer5f contains this symbol:

# nm -gC gpt.aer5f | grep Gpt_EnableNotification
00000811 T Gpt_EnableNotification

There are any constraints that I am missing?

You also need to include the gpt header files into sciserver make file.

Also, MCAL driver frame work is different from PDK, as MCAL follows AUTOSAR Specification has configuration file.

Yes I have included also.

So this shouldn't work? Other option is to include directly the source files, but I considered first using the builded library of gpt.

Yes, with this I have a problem. I am including all the required headers like this:

INCDIR += Gpt/include/ \
          $(MCUSW_PATH)/mcal_drv/mcal/Bsw_Stubs/AsrGnrl/inc/ \
          $(MCUSW_PATH)/mcal_drv/mcal/Bsw_Stubs/EcuM/inc/ \
          $(MCUSW_PATH)/mcal_drv/mcal/Bsw_Stubs/Dem/inc/ \
          $(MCUSW_PATH)/mcal_drv/mcal/Bsw_Stubs/Det/inc/ \
          $(MCUSW_PATH)/mcal_drv/mcal \
          $(MCUSW_PATH)/mcal_drv/mcal/Bsw_Stubs/MemMap/inc/ \
          $(MCUSW_PATH)/mcal_drv/mcal/Bsw_Stubs/Os/inc/ \
          $(MCUSW_PATH)/mcuss_demos/Bsw_Stubs/Rte/inc

And requires an define: AUTOSAR_431 or AUTOSAR_421. However I am defining in my main header file the other subsequent headers are not seeing it. I tried to use the CFLAGS_LOCAL_COMMON += -DAUTOSAR_431 but doesn't work.

If you need basic gpt operations, it would be better to add functions and header files required instead of linking library.

Thanks, I will do that.

What is your use-case and the OS using?
If you want to have Gpt+ Sciserver, then you can integrate sci-server into Gpt, for this please refer to CDDIPC examples in TI SDK.

Your on point I want to use Sciserver+GPT.

I found the problem. In makefile, some lines above there was an overwrite in the CFLAGS_LOCAL_COMMON.
Thanks for help. At the moment I don't have any questions.
