TMS570LS0432: Starting LED Blinking Program

Hi Tyagi,

Modify the code as below and test it

/* USER CODE BEGIN (0) */
#include "het.h"
#include "esm.h"
/* USER CODE END */

/* Include Files */

#include "sys_common.h"
#include "gio.h"

/* USER CODE BEGIN (1) */
/* USER CODE END */

int main(void)
{
/* USER CODE BEGIN (3) */
   // set port pins to output
   //gioPORTA.DIR |= (1U << 2);
   gioSetDirection(hetPORT1, 0xFFFFFFFF);

       while (1)
       {
           // Turn on the LED
          //gioPORTA.DSET = (1U << 2);
          gioSetBit(hetPORT1, 5, 1); // GIOA2 //on 5th pin led present
       }

/* USER CODE END */

 //   return 0;
}


/* USER CODE BEGIN (4) */

 void gioNotification(gioPORT_t *port, uint32 bit)
{
    return;
}

void esmGroup1Notification(esmBASE_t *esm, uint32 channel)
{
    return;
}

void esmGroup2Notification(esmBASE_t *esm, uint32 channel)
{
    return;
}
/* USER CODE END */

Hi Jagdish,

I tried this but, same error is persists.

"../source/sys_main.c", line 41: error #148: declaration is incompatible with "void esmGroup1Notification(uint32)" 
"../source/sys_main.c", line 46: error #148: declaration is incompatible with "void esmGroup2Notification(uint32)" 

Hi Tyagi,

One more small modification is required, here is the code you need to try

/* USER CODE BEGIN (0) */
#include "het.h"
#include "esm.h"
/* USER CODE END */

/* Include Files */

#include "sys_common.h"
#include "gio.h"

/* USER CODE BEGIN (1) */
/* USER CODE END */

int main(void)
{
/* USER CODE BEGIN (3) */
   // set port pins to output
   //gioPORTA.DIR |= (1U << 2);
   gioSetDirection(hetPORT1, 0xFFFFFFFF);

       while (1)
       {
           // Turn on the LED
          //gioPORTA.DSET = (1U << 2);
          gioSetBit(hetPORT1, 5, 1); // GIOA2 //on 5th pin led present
       }

/* USER CODE END */

 //   return 0;
}


/* USER CODE BEGIN (4) */

 void gioNotification(gioPORT_t *port, uint32 bit)
{
    return;
}

void esmGroup1Notification(uint32 channel)
{
    return;
}

void esmGroup2Notification(uint32 channel)
{
    return;
}
/* USER CODE END */

Hi Jagdish, 

I am sharing output of build of this but before that i want to confirm on line number 25 i have given 5 pin number and assigned value high as 1 so this is the correct way of doing this or i need to change it.

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

Hi Vishal,

I can't see the complete build, i don't see the name of symbol that was missing there.

Vishal Tyagi said:

5th pin means controller 5th pin you have LED right?

If possible, can you please share the schematic of LED where exactly it was connected.

Or else just give the details of the board you are using and mention the LED which you want to turn ON? so that i will open the corresponding schematic and verify the pin number.

Sure Jagdish,

Please find board details on below link 

https://www.ti.com/lit/ug/spnu612a/spnu612a.pdf?ts=1705409474734&ref_url=https%253A%252F%252Fwww.google.com%252F

And led position is on GIOA2 ON pin number 5.

Your basic problems is that your prototypes (which you do not show us) do not agree with your functions.

Your function has the signature

void esmGroup1Notification(esmBASE_t *esm, uint32 channel)

but your prototype is indicated to be:

"void esmGroup1Notification(uint32)"

So you have two arguments in the function, but only one in the prototype.

Hi Keith

In function 

void esmGroup1Notification(uint32 channel)
{
return;
}

Yes I am passing only one argument,  as function definition also have same parameter in declaration. 

I am sharing complete build result for reference.

Hi Tyagi,

Actually, the way you are doing is wrong.

 gioSetBit(hetPORT1, 5, 1); // GIOA2 //on 5th pin led present

The above line is not correct to SET the GIOA2, actually it will set the HET port 5th pin, i.e. N2HET[5]. This is because you are passing the hetPORT1 as first argument to the gioSetBit function and second argument is 5th bit, so that means you are saying you want to SET the 5th bit of N2HET.

So, this is not correct. If you really want to SET the GIOA2 bit then do the following thing.

You should pass the first argument as gioPORTA and second as 2 to the gioSetBit function, if you do that then it will SET the GIOA2 bit.

I could see you are also getting undefined symbol errors for gioSetBit and gioSetDirection function right? this is because you didn't generate the GIO driver from HALCoGen, then only you will get this error.

Make sure you enabled the GIO driver in HALCoGen.

Also make sure you generate the code after you enabled the driver.

I created one project for your requirement. Please use this project as reference and you can also use this project directly to test the GIOA2.

LED_TEST_TMS570LS0432.zip

I build this project and i don't see any errors:

But i didn't test this project as i don't have TMS570LS0432 board, so please test it and let me know the result.

Hi Jagdish,

Thank you for detailed reply

I Modified the changes and build the project it does not show any error but upon flashing, LED is not Turned ON, I tried with the project file you shared with that also LED is not turning ON, I have checked the Schematics of board on following link:

https://www.ti.com/lit/ug/spnu612a/spnu612a.pdf?ts=1705409474734&ref_url=https%253A%252F%252Fwww.google.com%252F

This is confirmed that LED Position is on 5th PIN number(GIOA2).

I tired adding these lines also 

void gioNotification(gioPORT_t *port, uint32 bit)
{
    return;
}

void esmGroup1Notification(uint32 channel)
{
    return;
}

void esmGroup2Notification(uint32 channel)
{
    return;
}

But LED is not turning ON.

Hi Tyagi,

The code should work. As i said i don't have board to test it.

Is it possible for you to setup a meeting with me, show your screen and i will guide you.

In our organization we are using webex for meetings.

If you are okay with that, then please mention your convenient time for meeting.
