Compiler/AM6548: ETH-CAN gateway demo build errors

Johnny Smith
Expert 1330 points

Part Number: AM6548
Other Parts Discussed in Thread: TMDX654IDKEVM

Tool/software: TI C/C++ Compiler

Hi all,

I am attempting build the CAN-ETH gateway example from CCS by creating a project and importing the source and build files. The project will be tested on the TMDX654IDKEVM, and the purpose is to get it running from CCS to make development of this simpler. At the moment I am quite stuck and was hoping someone could provide some assistance to make this work.

The following 2 error codes I am finding trouble resolving:

1) symbol "Osal_free" redefined: first defined in "./gateway_osal.obj"; redefined in "./utils_prf.obj" null: symbol "Osal_free" redefined: first defined in "./gateway_osal.obj"; redefined in "./utils_prf.obj"

2) unresolved symbol Board_init, first referenced in ./gateway_main.obj gatewayapp

There are plenty other errors as well as expected, but all are of the same for as the abovementioned. See the text file of the Console Build Log:

I am not very sure as to what the cause of these errors might be, as all my header files seems to included correctly and contains the necessary declarations as well. Does seems as if the ARM linker is not linking the correct libraries (if linking any at all). However I am confused to what exact libraries to link it to:

The includes path can also be seenbelow:

I would greatly appreciate any assistance or advise as to what the cause of these problems might be, so that I can get these errors fixed. The complete project is also attached in the following .zip file if you would wish to try an reproduce the error: gatewayapp_test.zip

The following is true for my project:

- CCS: v9.1.0.00010

- Processor SDK RTOS for AM65xx v5.03.00.07

- SYS/BIOS v6.75.02.00

- NDK v3.40.01.01

- XDCTools v3.51.01.18_core

Any assistance or advise is greatly appreciated! Please let me know if any other info is required.

Kind regards,

Johnny

    Hi,

    So I seem to have made some progress regarding this.

    Under Project->Properties->ARM Linker->File Search Path I added the search paths to the library files of all the drives mentioned in http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_examples_demos.html#can-eth-gatway-demo. These added paths can be seen in the screenshot below:

    I also added the following libraries from these included paths, which can be seen below:

    This solves most of the errors of the form: "unresolved symbol Board_init, first referenced in ./gateway_main.obj gatewayapp". However I am still struggling to figure out where these errors that I am still getting are coming from regarding the OSAL drive.

    For example symbol "Osal_free" redefined: first defined in "./gateway_osal.obj"; redefined in "./utils_prf.obj" null: symbol "Osal_free" redefined: first defined in "./gateway_osal.obj"; redefined in "./utils_prf.obj"

    The complete build log can be found in the following .txt document:

    Where does these errors come from? Any assistance would be greatly appreciated.

    Hi Johnny,

    The OSAL_free redefined issue was cause by the inclusion of gateway_osal.c in your project. If you check the processor_sdk_rtos_am65xx_5_03_00_07\demos\gateway-demos\can-eth-gateway\build\makefile.mk, you will see the utils_prf.c is included, but gateway_osal,c is not.

    Best regards,

    Ming
