richa m,

The problem mentioned:
> ERROR-------
> >> warning: entry point symbol _c_int00 undefined
is from a missing library in the project setup, nothing wrong with the source code.
This does not mean a reference to the specific library is missing from the list of files;
rather that Project/,,, is missing the lib path info.

Thanks a ton for so many response and your response have actually helped me to move further.
Now the problem i am facing is that i have to make
# define GPIo_support 1 and
# define inline 1,,,,,,,,before i include csl_gpio.h
however i am getting gpio_open ,gpio_pindirection etc as first time referenced symbols

if i do not define gpio_support as 1 then it gives error gpio_handle as undefined....though after making gpio_support as 1 ,,,,i do not get gpio_handle as undefined.....

but i am still confused ,,,,,as after i make usedefs as 1,,,my code starts compiling
#include

//#define chip_6201
#define CHIP_DA610

#include "C6x.h"

#include "csl_chiphal.h"

//#define _GPIO_MOD_

Has anyone faced such a problem.....if you want i can share my csl_gpio.h file also.....

Please check this out....

Please someone help me how to toggle GPIO pins .I am getting GPIO symbols as undefined.I am using code composer for this purpose....

Richa,

The following code snippit may be just what you are looking for.

R. Williams

======================// Include:
#include
// Variable:
GPIO_Handle hGpio;
// somewhere in your main:
unsigned b=0;

hGpio = GPIO_open(GPIO_DEV0,GPIO_OPEN_RESET);
GPIO_pinEnable(hGpio,GPIO_PIN0);
GPIO_pinDirection(hGpio, GPIO_PIN0,GPIO_OUTPUT);

GPIO_pinWrite(hGpio,GPIO_PIN0,b);

Use

#define CHIP_DM6446

instead of

#define chip_DM6446

!!!!

I suggest you should read at least the GPIO section of the DM6446 doku.

If you use TMS320DM6446 ( which I don't know) I think your define should
look like '#define chip_DM6446'. Have a look at CSL_init() in csl.h what
chips are available.

Maybe you have a typo in 'GP0EN' or 'GP0DIR' try to find them in the
include files.

Thanx for your response.I have not read TMS320DM6446 processor extensively.Just my org. has told me to set GPIO pin as Input or Output and then toggle it

But my problem is that i am getting undefined symbols for all my GPIO signals If you have a little code snippet dealing GPIO signals thn please send it to me I am copying my code with this mail.I f you can help me.

the error is no chip defined, you have to define on what chip you are working...C6713 I think

Add something like

#define CHIP_6467 1

_BEFORE_ including any CSL files!
