    Hello JY,

    I have forwarded your question to the author of the app note and the project. They should get back to you soon.

    Hello JY,

    Looks like the issue is due to FreeRTOS version.

    Can you use the TI-Design (www.ti.com/.../TIDM-TM4C129XS2E) instead? This is a more updated version of the application. Let us know if you have the similar issues building this project.

    Thanks,
    Sai

    Hello,

    I have the same problem as Jae Yong Koh with the build of enet_s2e example for my EK-TM4C1294XL launchpad. I have the same version of Tiva-Ware (TivaWare_C_Series-2.1.2.111).

    The link you provided in your last answer leads nowhere. Can you give us a link to the updated version of the application please?

    Thanks,
    Alex

    Hello Amit,

    I have downloaded the .zip file from the link you gave me. I copied the enet_s2e folder to C:\ti\TivaWare_C_Series-2.1.2.111\examples\boards\ek-tm4c1294xl. I imported the enet_s2e to my CCS workspace (CCS  Version: 6.1.3.00033), but I still have the same build error.

    Thanks,

    Alex

    Hello Alex

    In the file FreeRTOSConfig.h

    replace the line

    #define configMAX_PRIORITIES ( ( unsigned portBASE_TYPE ) 16 )

    with

    #define configMAX_PRIORITIES ( 16 )

    Regards,
    Amit

    Hello Amit,

    I replaced the line in the file FreeRTOSConfig.h like you told me. However, I still have some building errors. I uploaded an image to show the remaining errors.

    Thanks,

    Alex

    Hello Alex,

    Yes, I saw it too and this is because the RTOS version has been changed causing the function to be removed. I have reported this to the TI Design author as well, and waiting for an update from him.

    Hello Alex,

    Sorry for the delay. As noted before the compilation error is generated because the FreeRTOS version in TivaWare 2.1.2 has been updated.

    I did the following modifications and the application builds successfully. Some of these modifications were covered by Amit, but I am including all the necessary modifications in one place here.

    • In the file "FreeRTOSConfig.h" replace the line
    #define configMAX_PRIORITIES                ( ( unsigned portBASE_TYPE ) 16 )

    with

    #define configMAX_PRIORITIES                16
    • In the file "serial_task.c" replace all instances of
    vPortYield();

    with

    portYIELD();

    In the same file, replace the following line

     if(xTaskCreate(SerialTask, (signed portCHAR *)"Serial",

    with

    if(xTaskCreate(SerialTask, (const portCHAR *)"Serial",

    Thanks,

    Sai

    I started having the same problem, I did the changes but the project still does not compile.

    The number of  errors was reduced from 18 to 5, and I still have the following errors:

    Type unresolved symbol portYield, first referenced in ./serial_task.obj 

    Type #10010 errors encountered during linking; 

    #10234-D</a> unresolved symbols remain 

    Type gmake: *** [enet_s2e.out] Error 1 

    Type gmake: Target 'all' not remade because of errors.

    #10234-D</a> unresolved symbols remain 

    ype #10010 errors encountered during linking; 

    Any help would be appreciated.

    Solved the problem now: in FreeRTOS V8.2.3 all occurrences of "vPortYield" must be changed to "portYELD" (case sensitive).
