LPC1517 SWD Flash Programming Failure

Hi,
Using uvision 4.70 and Ulink2 (fw 2.02) fail to flash LPC1517 with :
"Error: flash Download failed - Cortex-M3" only at those addreses :
Programming Done.
Contents mismatch at: 0000001CH (Flash=86H Required=00H) !
Contents mismatch at: 0000001DH (Flash=F6H Required=00H) !
Contents mismatch at: 0000001EH (Flash=FFH Required=00H) !
Contents mismatch at: 0000001FH (Flash=FDH Required=00H) !
Verify Failed!

Checked the device with FlashMagic and it is programmed correctly
(the flashmagic verification is passed and indicated bytes are "00h") ;
seems that is only the ULINK2 verify that fails !

I've seen that exactly the same problem has been reported for a LPC1114 :

but no solution has been reported.

I'm looking for a solution.

Tanks and Best Regards,
Andrea.
