Objet : [lpc2000] IAP erase

   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);
 }
