FRDM-KE02Z with IAR

[manjitduhan]

Hi, I am new to ARM. I had a FRDM-KE02Z board. When I program it with demo code it works but when I make my project it doesn't.

is startup.s fille is required?

my code is given below:-

#include "MKE02Z2.h"

#define LED0_Init()    GPIOB_PDDR |= (2<<24)    
#define LED0_Toggle()      GPIOB_PTOR = (2<<24)
#define LED0_On()          GPIOB_PCOR = (2<<24)
#define LED0_Off()          GPIOB_PSOR = (2<<24)

#define LED1_Init()    GPIOB_PDDR |= (4<<24)   
#define LED1_Toggle()      GPIOB_PTOR = (4<<24)
#define LED1_On()          GPIOB_PCOR = (4<<24)
#define LED1_Off()          GPIOB_PSOR = (4<<24)

#define LED2_Init()    GPIOB_PDDR |= (0x01<<7)
#define LED2_Toggle()      GPIOB_PTOR = (0x01<<7)
#define LED2_On()          GPIOB_PCOR = (0x01<<7)
#define LED2_Off()          GPIOB_PSOR = (0x01<<7)

/********************************************************************/
int main (void)
{
    LED0_Init();
    LED1_Init();
    LED2_Init();

    LED0_Off();
    LED1_Off();
    LED2_Off();

    while(1)
  {
                  LED0_On();
                  LED0_Off();
                  LED1_On();
                  LED1_Off();
                  LED2_On();
                  LED2_Off();
    
  }
}

I got my solution.

I was not disabling WATCHDOG.

Hi, Manjit

For ARM core itself, such s file is not must. I think you might use KEIL IDE for your project development. So I suggest you reference our sample project for your start.

Please reference this link FRDM-KE02Z: Kinetis E Series Freedom Development Platform. Project name is KE02-SC.

Hope my reply can help you.

Best Regards

Paul

hi Paul

Is there any need to include any startup file in project? What if I don't include any?

I had not included any startup file, some time its work perfectly but some time not.

One more question, is there any fuses/lock setting in these MCU's? from wher can I get this info about these mcu's.

Hi Paul,

Thanx for your advice. But I can't use KEIL as its not available in our org.

Do you have any idea which startup file should I use?
