I'm trying to debug NfcrdlibEx3_NFCForum example on my custom lpc11u68 based board,

I'm using LPCXpresso 8.2.2 and NFC-Reader-Library-v04.030.00.011627 and LPC-link2.

I can successfully Debug and run NfcrdlibEx4_MIFAREClassic example on my board,and examples are debugged in LPC1769 based evaluation boards,but when I'm trying to debug NFCForum example ,IDE shows :

15: Target error from Commit Flash write: Ef(34): Timed-out initializing flash.
Also I Feed LPC11u68 with external 3v3 0.5A PSU but no success,

This is my debug log:
