J-Link, Keil-µVision3, phyCORE LPC3250 (Arm9) shows Error "Cannot stop arm device"

I'm using the J-Link ARM V4.08 with Keil latest Compiler Tools µVision3 and the Phytec Developement kit with ARM9 LPC3250.

Debugging doesn't work properly, in 9 of 10 cases I get the error "cannot stop ARM device" message line shows "faild to read ICE breaker after reset".

In one of 10 cases debugging works, but reseting the CPU shows up similar errors (registers can#t be read die core is not stopping).

I used several settings for the Jlink driver J-Tag speed, Reset options, but none of them improves the behaviour.

Does anybody know about the problem?
