Lpc2000

Hi everybody,

some problem during using the IAP functions of the lpc2294. I have 
wrote this sample code:

int iFlashRAMCopy (unsigned long DestinationFlashAddress, unsigned 
long SourceRAMAddress,
                   unsigned int BytesToWrite, unsigned long 
ProcFrequency, unsigned char StartSector, unsigned char EndSector)
{
 unsigned long command[5];
 unsigned long result[2] = {0,0};

  
 disable_interrupt();

 command[0] = FLASH_PREPARE_SECTOR_TO_WRITE;
 command[1] = StartSector;
 command[2] = EndSector;
 command[3] = ProcFrequency;

 iap_entry (command, result);


 if (CMD_SUCCESS == *result)
  {
   command[0] = FLASH_COPY_TO_RAM;
   command[1] = DestinationFlashAddress;
   command[2] = SourceRAMAddress;
   command[3] = BytesToWrite;
   command[4] = ProcFrequency;
   iap_entry (command, result);
  }

 enable_interrupt();

 return (CMD_SUCCESS == *result);

everytime when i try now to copy a part from the ram eg 0x81000000 to 
flash eg. 0x4000 the second iap_entry call me the error 4 - "mapping 
error" - whats wrong ? My program runs on external mem at 0x81000000! 

Greetings
M. Walter

everything is ok now, i have found my error ...
