Hello Cris,
 
                 In your code result[1] contains the ID...you should return result[1] instead of result[0]. results[0] only says the cammand is sucess.
 
regards,

Hello friends,

I'm still pretty unexperienced in programming the LPC2xxx processors. 
I want read and write the internal flash using IAP. At first, I tried 
to read the processor ID from the flash.

My code is:

int IAP_ID()
{
#define IAP_LOCATION 0x7FFFFFF1
unsigned int command[5];
unsigned int result[2];
typedef void (*IAP)(unsigned int[],unsigned int[]);
IAP iap_entry;

int ID;
int Ergebnis;
  __DISABLE_INTERRUPT();
iap_entry=(IAP)IAP_LOCATION;
command[0]=54;             //read par ID
result[0]=0;
iap_entry(command,result);
Ergebnis=result[0];
ID=result[1];
return Ergebnis;
} 

By the way, I use the ICCARM compiler, the boot loader version is 1.64

Is there anybody who can help me? As I learned from this forum, the 
problem might laying in switching to the thumb mode when calling the 
IAP-routine. Who do I have to do this?

Best regards

Cris
