Error in LED-blinking projects

Hi..

I am trying to run LED-blinking project with TMS320F28335 in code composer studio v5.

But it shows this error :

undefined first referenced
symbol in file
--------- ----------------
_delay_loop ./main.obj

error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "28335-blink-LED.out" not built

>> Compilation failure
gmake: *** [28335-blink-LED.out] Error 1
gmake: Target `all' not remade because of errors.

I try to run the project with the Code :

#include "DSP28x_Project.h"

void main(void) {

void delay_loop(void);
{
volatile long i;
for (i = 0; i < 5000000; i++) {}
}


{
EALLOW;
GpioCtrlRegs.GPAPUD.bit.GPIO31 = 0;
GpioCtrlRegs.GPAMUX2.bit.GPIO31 = 0;
GpioCtrlRegs.GPADIR.bit.GPIO31 = 1;
GpioCtrlRegs.GPBPUD.bit.GPIO34 = 0;
GpioCtrlRegs.GPBMUX1.bit.GPIO34 = 0;
GpioCtrlRegs.GPBDIR.bit.GPIO34 = 1;
EDIS;
}
for(;;)
{
GpioDataRegs.GPASET.bit.GPIO31 = 1;
GpioDataRegs.GPBCLEAR.bit.GPIO34 = 0;

delay_loop();

GpioDataRegs.GPACLEAR.bit.GPIO31 = 0;
GpioDataRegs.GPBSET.bit.GPIO34 = 1;

delay_loop();
}
}

Please tell me is there any mistake in code and how can I solve this unresolved symbols remain error.

Thanks

    Mehul,

    Could you tell me where you found this project in controlSUITE and which version of controlSUITE you have?

    The only blinking LED project I know of for the F28335 is in:

    C:\ti\controlSUITE\development_kits\TemplateProjects\FlashingLeds-F28335_v1.0

    I just imported and compiled the project successfully in CCSv5.

    Hello Trey,

    Thank you for answer.

    I did not found this project from controlSUITE. I made it myself to check that by setting & clearing of GPIO pins instead of toggling, LEDs are blinking or not. 

    would it be possible to blink LEDs with the code that I mentioned above?

    The C:\ti\controlSUITE\development_kits\TemplateProjects\FlashingLeds-F28335 project is not working. it shows some error in device selection.

    could you send me web-link to download correct version of controlSUIT.

    The project in controlSUITE should work.  Could you further describe the error you have with it?  Maybe post up a screen shot?

    The latest version of controlSUITE should be the version you're using.  ControlSUITE can be downloaded from ti.com/controlSUITE.

    I think the problem with your original code is that the delay function is inside of the main function.  If you separate them out the code should start compiling.

    Hi Trey,

    I hope this sounds silly. But i got stopped over here.

    I hve installed Control suite & trying to run few examples for delfino F28335 control stick with c2000 explorer kit.

    Problem :

    In control Suite, i could see few examples , where control suite GUI show step 1 , step 2 ... to run the examples.

    but when i expand the "view all 45 examples", i couldn't see those step1,step2...to run it.

    please let know , how to call those examples..

    Note: i am trying to run led blinking for F28335. please let me know how to run led blinking from control suite for delfino f28335.

    thanks.
