Hi,
I am also trying to acces IAP commands, without success (LPC1114).
If I try to reinvoke ISP doing the followings, it just hangs:

#define IAP_LOCATION 0x1fff1ff1
unsigned long command[5];
unsigned long result[4];
void (*iap_entry)(unsigned long *, unsigned long *) = (void *)IAP_LOCATION;

void ReinvokeISP(void)
{
    command[0]=57;
    iap_entry (command, result);
}
Am I doing something wrong ?
Thanks for your help.

I suggest you start by reading the chapter "LPC111x Flash memory programming firmware" in the LPC11xx User Manual available from the NXP website.

The following thread also contains a discussion on this issue...

The USB secondary bootloader example for the RDB1768 (included in your LPCXpresso install's examples subdirectory) provides code which might be useful to look at too, though this is for the LPC17xx rather than the LPC11xx.
