initiation ethernet block lpc1768, target error 15

I am trying to initiate the Ethernet block on a lpc1768.

The block is powered up. The pins are set

EMAC-MAC1 reset is set and deasserted.

EMAC-Command reset set.

Next step is initialising MAC control registers.

EMAC-MAC1 = all pass flag set etc..

At this point  SW debug breaks down.

 

15: Target error from Register access: Ee(FF). Redlink interface error 255.

It is impossible to pass this point in the program. Whatever I skip in the rest of the program after reset of the MAC I either get this message or the program gets somewhere in loop.

When I stop the debug. It takes some time before the IDE responds with terminating the process all together.

 

Who has a solution?
