Code Snippet 1:

When I "Build" the code, I got following errors.
#include "Bootloader.h"
#include "IFsh1.h"
#include "S19.h"
#include "Shell.h"
#include "WAIT1.h"
#include "LEDR.h"
#include "UTIL1.h"
#include "AS1.h"
#include "KIN1.h"

#define FLASH_PAGE_SIZE             (IntFlashLdd1_ERASABLE_UNIT_SIZE) /* flash page size */
#define BL_FLASH_VECTOR_TABLE       0x0000 /* bootloader vector table in flash */
/* application flash area */
#define MIN_APP_FLASH_ADDRESS        0x1000  /* start of application flash area */
#define MAX_APP_FLASH_ADDRESS       0x7FFFF  /* end of application flash */

#define APP_FLASH_VECTOR_START      0x1000  /* application vector table in flash */
#define APP_FLASH_VECTOR_SIZE       0x410    /* size of vector table */

Code Snippet 2:

#include "BL_SW.h"
#include "PORT_PDD.h"
static bool BL_CheckBootloaderMode(void) {
  /* let's check if the user presses the BTLD switch. Need to configure the pin first */
  /* PTB1 as input */
  /* clock all port pins */
  SIM_SCGC5   |= SIM_SCGC5_PORTA_MASK |
             SIM_SCGC5_PORTB_MASK |
             SIM_SCGC5_PORTC_MASK |
             SIM_SCGC5_PORTD_MASK |
             SIM_SCGC5_PORTE_MASK;
  /* Configure pin as input */
#if 0
 /* GPIOB_PDDR: PDD&=~0x0100 */
 GPIOB_PDDR = (uint32_t)((GPIOB_PDDR & (uint32_t)~0x0100UL) | (uint32_t)0x00UL);
 /* Initialization of Port Control register */
 /* PORTB_PCR1: ISF=0,MUX=1 */
 PORTB_PCR1 = (uint32_t)((PORTB_PCR1 & (uint32_t)~0x01000600UL) | (uint32_t)0x0100UL);
#else
  (void)BitIoLdd1_Init(NULL); /* initialize the port pin PTB8 */
  /* enable internal pull-up on PTB1 */
  PORT_PDD_EnablePullupLowPortMask(PORTB_BASE_PTR, 1, PORT_PDD_PULL_UP);
  PORT_PDD_SetPinPullEnable(PORTB_BASE_PTR, 1, PORT_PDD_PULL_ENABLE);

  WAIT1_Waitms(5); /* wait get pull-up a chance to pull-up */
  #endif
    if (!BL_SW_GetVal()) { /* button pressed (has pull-up!) */
      WAIT1_Waitms(50); /* wait to debounce */
      if (!BL_SW_GetVal()) { /* still pressed */
        return TRUE; /* go into boot loader mode */
      }
    }
    /* BTLD switch not pressed, and we have a valid user application vector */
    return FALSE; /* do not enter boot loader mode */
  }

In The Above 2 Code Snippets, error was thrown when I "build" my project in Kinetis Design Studio IDE. The statements which threw error are marked in BOLD font style.
The error statement in code snippet 1 is:

Quote:

Multiple markers at this line
- 'IntFlashLdd1_ERASABLE_UNIT_SIZE' undeclared (first use in this
function)
- each undeclared identifier is reported only once for each function it
appears in

The error statement in code snippet 2 is:

What I have tried:

I am using

Hardware: MKE02Z64VLD2

IDE: Kinetis Design Studio.

BL_SW: PTB1

I posted this doubt in many forums and they said, the syntax is not supporting the Kinetis E series controller. They asked me to refer the reference manual of the Kinetis E series controller. But in the reference manual I could not find the proper syntax to fix these errors.

In a nutshell,
In the code snippet 1, I am trying to define a variable for Flash Page Size, but the bad syntax is not supporting KE-02Z controller.
In the code snippet 2, the operation which I am trying to perform with the code snippet 2 is Clocking all the Port Pins, Configuring the PORTB Pin1 (PTB1) as input and, Initialize the port pin PTB1, Enable internal pull-up on PTB1 followed by simple wait statements.
And the Problem with the code snippet 2 is those SIM instruction wont support Kinetis E series controller and the Port Pins are automatically clocked by default after reset. So those 5 statements can just be deleted right ?
Next Error occurs at statements pertaining to enabling the Internal Pull up. How to fix it ?
(Sorry for the long question, my question is pretty straightforward but to make the reader understand my question is quite difficult.)
Thanks in advance.
