Lpc2000

Hi all.

I write this code for erase flash of a LPC2106.
This code is base on some code I found on Internet.
I when to know what is a SectorStar? that resembles to?
Flash sector prepare give me a result of 7. What that mean?

Thank.

int EraseSectors(unsigned int SectorStart, unsigned int SectorEnd,
unsigned long ProcFrequency)
{
   unsigned long command[5]; 
   unsigned long result[2]; 

   IAP iap_entry = (IAP) IAP_LOCATION; 

  __disable_interrupt(); 

  command[0] = FLASH_PREPARE_SECTOR_TO_WRITE; 
  command[1] = SectorStart; 
  command[2] = SectorEnd; 
  command[3] = ProcFrequency; 

  iap_entry(command, result);

// result[0] always give me 7!!! I don't know what is this error.

  if (CMD_SUCCESS == *result) {
    command[0] = FLASH_ERASE_SECTORS; 

    iap_entry(command, result); 
  }

  __enable_interrupt(); 

   return (CMD_SUCCESS == *result);
}

The error 7 is for INVALID_SECTOR

The User Manual for the LPC2106 has a fine reference of the IAP.  Please 
read it.  They even give the error codes.  Then read the section of the 
manual which describes the internal Flash Memory.

The Philips documentation may be slim in some areas, but it is very good 
about the Flash & IAP.
