Debugging LPC812 Cortex m0 MCUs

Hi
is this possible to debugging applications on this MCU?has any one experiences with this?As Datasheet says it is possible to debugging in SWD mode but with JLINK /Keil we had no success.
I used small breakout board & soldered lpc812 pins as described in datasheet for debaugging
Keil shows this error:
