SK-AM62P-LP: Issue with FreeRTOS vTaskDelayUntil

Debashis Mahanty

Part Number: SK-AM62P-LP

Tool/software:

Hi experts,

I want a task to run periodically every 1 ms, so I have used the code below.

TickType_t xLastWakeTime;
    const TickType_t xFrequency = pdMS_TO_TICKS(1);
    // Initialise the xLastWakeTime variable with the current time.
    xLastWakeTime = xTaskGetTickCount();
    while(1)
    {
        if (gbShutdown == 1u)
        {
            break;
        }

        /*User code as per application*/

        vTaskDelayUntil( &xLastWakeTime, xFrequency );


    }

I don't know why this error is coming can you help me to resolve this.
When I searched for the task.c file, I found a macro-guarded(#if ( INCLUDE_xTaskDelayUntil == 1)), but unfortunately, I didn't find that in the included header files.

error that I received while compiling is more likely in the make file.

Debashis

Hi Debashis,

The subject matter expert is out of office this & next week. So responses to this thread will be delayed. Thanks for your patience.

Meanwhile, Can you please send us the complete error logs that come up while building the project?

Yes, I think you mean the console.

Hi Debashis,

Thanks for sharing the above details.

Please add the below macro definition to FreeRTOSConfig.h file located at ${MCU+SDK}/source/kernel/freertos/config/am62px/r5f.

Please refer below image.

Once the macro definition has been added, please rebuild the libraries. Run the below command from root directory of MCU+SDK.

cd source/kernel/freertos/

gmake -s -f makefile.am62px.r5f.ti-arm-clang PROFILE=debug clean
gmake -s -f makefile.am62px.r5f.ti-arm-clang PROFILE=release clean

gmake -s -f makefile.am62px.r5f.ti-arm-clang PROFILE=debug 
gmake -s -f makefile.am62px.r5f.ti-arm-clang PROFILE=release

After building the libraries, rebuild the example project. You will now be able to build it without errors.

Please let us know if the above solution works.

Regards,

Tushar

Hi Tushar,

Thanks for your support. It's working fine now. I have tried this, but as you said, I wasn't aware of the build.
When I saw the tasks.c file, I could see that it's guarded with this macro, but I wasn't aware that we have to build this. Can you share any documents so I can read if any more info is there regarding RTOS? It's helping me out.

Regards,
Debashis

Hi Debashis,

Thanks for the above confirmation.

Please refer /KERNEL_FREERTOS_IMPORTANT_GUIDELINES for details. If you change anything in the source of MCU+SDK it is necessary to build the libraries for the changes to take place.

Please refer Using SDK with makefiles for details.

Tushar
