Hello,
I don't know the keil sources, but might you have forgotten to disable interrupts during IAP-call?
And are you sure that your code is calling this IAP-routine correctly (THUMB mode)?

...
typedef void (*IAPCall_t)(u32*, u32*);
...
int iap_write(const void* destAddr, const void* srcAddr, unsigned long int size) {
IAPCall_t iap_call = (IAPCall_t) 0x7ffffff1;
u32 cbits;
u32 cmdres[5];
...
...
cmdres[0] = 50; /* Prepare sector */
cmdres[1] = sSect;
cmdres[2] = eSect;
cbits = kernel_beginCritical();
iap_call(cmdres, cmdres);
kernel_endCritical(cbits);
...
cmdres[0] = 51; /* Copy RAM 2 Flash */
cmdres[1] = (u32) p;
cmdres[2] = (u32) tmp;
cmdres[3] = 256;
cmdres[4] = pll_core_clock_khz;
cbits = kernel_beginCritical();
iap_call(cmdres, cmdres);
kernel_endCritical(cbits);

Do you need a tiny and efficient real time
operating system (RTOS) with a preemtive
multitasking for LPC2000 or AT91SAM7?

Or some open-source tools and code for LPC2000?
