ARM9 - Can't use Peripherals

Hi,
I'm using UV3 also UV4 with ARM7 (LPC2368/2478) with ULINK2 (Jtag). Everything works fine and I have the ability to debug the On-Board CPU.
I try to connect to LPC3250. It works (I Can program code and run) but The periperals menu is empty and I can't debug the LPC3250.

In the 'Target-Debug-Setting' the 'Jtag Device Chain' has:
0x1b900f0f - Unknown JTAG Device
0x17900f0f - ARM926EJ-S Core

Maybe the 'Unknown JTAG' is the problem - But how to solve it?
