Hi,

I have a TMDSCNCD28388D board and when i'm debugging CM RAM and CM FLASH blinky on code composer studio, gave mi a strange error doesn't take the file cm.out and I don't know why for CM RAM the debug work but when start runngiong the led doesn't blink, for CM FLASH gave the error that can linking cm.out because I see in the folder that doesn't exsist why?

Hi,

Are you running the code on CPU1 (C28x core) before running the CM side code? CPU1 is the master core on this device and it has to initialize the peripherals and boot the CM core post which the CM can start executing the code.

Also, I am unable to reproduce the compilation error that you are observing.

Best Regards

Siddharth

Sorry for delay in responding .

vectorTableFlash is defined in startup_cm.c , attaching the snaphot below of it

Can you check if "_FLASH" is available as predefined symbol in the Project properties as shown below?

Best Regards

Hi Siddharth,

I checked and the startup file exists, but it is startup.ccs, but I still can't find it in the project, it is not visible anywhere I found this information only on the interrupt.h file that I attached

Instead I found the _flash inside the properties of the predifined symbols

Thanks

startup_cm.c is included in the led_ex1_c28x_cm_blinky_cm project and it should be available in the following folder.

C:\ti\c2000\C2000Ware_5_04_00_00\device_support\f2838x\common\source

You can add this file to the project if it is not added to it and then recompile the project.

Best Regards

Hi Siddhart,

Yesterday I found the startup file, but still the code doesn't work, probably I found the problem of the CM FLASH, because I see that the CM RAM works, but not the flash, it say that vectorTableFlash in an undefined symbol, I have attached the problem

but in the startup file there is the definition of this vectorTableFlash

Thank & Regards

If the "_FLASH" symbol is defined in the project properties , it should not throw any error for "vectorTableFlash"

can you share the snaphot of the project properites with the predefined symbols?

I tried it out on my PC and I am able to compile the project without any error.

Best Regards

Siddharth

Hi Siddharth,

This is the screenshoot, the _FLASH symbol is defined

Thanks

The code is this

#include "driverlib_cm.h"
#include "cm.h"


//
// Main
//
void main(void)
{
    //
    // Initialize device clock and peripherals
    //
    CM_init();

    //
    // Initialize GPIO and configure the GPIO pin as a push-pull output
    //
    // This is configured by CPU1
    
    //
    // Loop Forever
    //
    for(;;)
    {
        //
        // Turn on LED
        //
        GPIO_writePin(DEVICE_GPIO_PIN_LED2, 0);

        //
        // Delay for 500000uS.
        //
        DEVICE_DELAY_US(100000);

        //
        // Turn off LED
        //
        GPIO_writePin(DEVICE_GPIO_PIN_LED2, 1);

        //
        // Delay for 500000uS.
        //
        DEVICE_DELAY_US(100000);
    }
}

//
// End of File

Can you try to delete the projects from the CCS workspace and try to import again from the C2000Ware folder?

for about this project C:\ti\c2000\C2000Ware_5_04_00_00\driverlib\f2838x\examples\c28x_cm\led

I don't have use it I used that there is in the get started of code composer studio and selecting the board device F28388D than keyword and than selected led_ex1_c28x_cm_blinky the cm flash from this project doesn't work, why ? you can try it?

It would be a great help

Thanks & Regards
