K60F120M flashing

[chandu_nav]

I have successfully flashed an LED blinking application on TWR K60F120M board but when I run the application the execution is unstoppable its going to some unknown memory I have flashed my code into flash address 0x00000000

Below is I have copied my code

#include "twr-k60f120m.h"
#include "mcg.h"
#include "cw.h"
#include "MK60F12.h"
void wait (void);

const int led_user1 = ((unsigned int) 0x01 << 11);
const int led_user2 = ((unsigned int) 0x01 << 28);
const int led_user3 = ((unsigned int) 0x01 << 29);
const int led_user4 = ((unsigned int) 0x01 << 10);

#define GPIO_PIN(x) (((1)<<(x & GPIO_PIN_MASK)))
#define GPIO_PIN_MASK 0x1Fu

void wait (void)
{
int i;
for(i=0;i<500000;i++);
}

int main (void)
{
//Set PTA10, PTA11, PTA28, and PTA29 (connected to LED's) for GPIO functionality
PORTA_PCR10=(0|PORT_PCR_MUX(1));
PORTA_PCR11=(0|PORT_PCR_MUX(1));
PORTA_PCR28=(0|PORT_PCR_MUX(1));
PORTA_PCR29=(0|PORT_PCR_MUX(1));

//Change PTA10, PTA11, PTA28, PTA29 to outputs
GPIOA_PDDR=GPIO_PDDR_PDD(GPIO_PIN(10) | GPIO_PIN(11) | GPIO_PIN(28) | GPIO_PIN(29));

for(;;)

{

//Set PTA10 to 0 (turns on blue LED)
GPIOA_PDOR&=~GPIO_PDOR_PDO(GPIO_PIN(10));
wait();
//Toggle the green LED on PTA29
GPIOA_PTOR|=GPIO_PDOR_PDO(GPIO_PIN(29));
wait();
//Set PTA28 to 0 (turns on yellow LED)
GPIOA_PDOR&=~GPIO_PDOR_PDO(GPIO_PIN(28));
wait();
//Set PTA11 to 0 (turns on orange LED)
GPIOA_PDOR&=~GPIO_PIN(11);
wait();

/* GPIOA_PCOR = led_user1;
- wait();
- GPIOA_PCOR = led_user2;
- wait();
- GPIOA_PCOR = led_user3;
- wait();
- GPIOA_PCOR = led_user4;
- wait();
-
- GPIOA_PDDR = led_user4;
- wait();
- GPIOA_PDDR = led_user3;
- wait();
- GPIOA_PDDR = led_user2;
- wait();
- GPIOA_PDDR = led_user1;
- wait();*/

}

Hi Naveen

Probably you have missed enabling clocks to the port and so it will hard faut when you try to use them.

Hi Mark, 

Thanks a lot for your reply, 

Could you please help me with enabling the clock for PORT A for your information I am not working with either IAR or CodeWarrior IDEs. The above given is my actual code please help me with enabling clock for PORT A. 

Thanks in advance.

Hi  Naveen,

You can refer the gpio example in KINETIS_120MHZ_SC.

Best Regards,

Robin

Set PORTA flag in SIM_SCGC5.

Or download the project in the link and start working with Ethernet, USB, SD card, etc. within 15 minutes (in CW and IAR).
