No source available for "0xfffffffe"

[leechen]

I'm trying to read data from EEPROM. I use LPC11u68.  When I read data from EEPROM, it shows "No source available for "0xfffffffe". Can any one help me?  I don't understand what I've done wrong. 

my code:

#define EEPROM_START_ADDRESS                      (0x00000040)

#define IAP_NUM_BYTES_TO_READ_WRITE         16

uint32_t buffer[IAP_NUM_BYTES_TO_READ_WRITE / sizeof(uint32_t)];

void readEEPROM(int addressEEPROM, uint32_t serial)
{
   uint32_t command[5], result[4];
   uint8_t *ptr = (uint8_t *) buffer;
   uint32_t i;

   / * Data to be read from EEPROM */
   command[0] = IAP_EEPROM_READ;
   command[1] = addressEEPROM;
   command[2] = (uint32_t) ptr;
   command[3] = IAP_NUM_BYTES_TO_READ_WRITE;
   command[4] = SystemCoreClock / 1000;
   iap_entry(command, result);

   for(i = 0 ; i < IAP_NUM_BYTES_TO_READ_WRITE ; i++)
   {
      testReceiverUID[serial][i] = *((uint8_t *)buffer + i);
   }
}

while(1)
{
   uint32_t i;

   readEEPROM(EEPROM_START_ADDRESS + (10 * IAP_NUM_BYTES_TO_READ_WRITE), 10);

}

(You must disable interrupts ; And from my experience, available too for LPC17xx) ;

Hi  Lee Chen

Thank you for your interest in NXP Semiconductor products and 

the opportunity to serve you.

To provide the fastest possible support, I'd like to suggest you to refer to the periph_eeprom demo which illustrates using IAP command to read, write EEPROM operations in LPCOpen library.

Have a great day,
TIC
