hi,
 
        when you invoke iap routine with command in command array , result array contain the status(result) of the operation.
Return Code may be 

CMD_SUCCESS |

COMPARE_ERROR |

COUNT_ERROR (Byte count is not a multiple of 4) |

ADDR_ERROR |

ADDR_NOT_MAPPED

0 - CMD_SUCCESS Command is executed successfully.

1 - INVALID_COMMAND Invalid command.

2 - SRC_ADDR_ERROR Source address is not on a word boundary.

3 - DST_ADDR_ERROR Destination address is not on a correct boundary.

4  -SRC_ADDR_NOT_MAPPED Source address is not mapped in the memory map.

u can get this inforamtion in flash memory system & programming section.
I hope it is what u expected.
 
Regards,
Pandurang S.

Subject: [lpc2000] erase flash memory thru command prompt


   
  For erasing the contents of flash memory from the command prompt  this is the syntax but what will be value of result
   
   
  unsigned long command[5];
  unsigned long result[2];
  or
  unsigned long * command;
  unsigned long * result;
  command=(unsigned long *) 0x.....
  result= (unsigned long *) 0x.....
  Define pointer to function type, which takes two parameters and returns void. Note the IAP returns the result with the base address of the table
  residing in R1.
  typedef void (*IAP)(unsigned int [],unsigned int[]);
  IAP iap_entry;
  Setting function pointer
  iap_entry=(IAP) IAP_LOCATION;
  Whenever user wishes to call IAP within the application, the following statement could be used.
  iap_entry (command, result);
   
  what will be the value of result
   
   
  thanks in advance
  Richa
