Hi, I have a Microvision 3 with C166 compiler. I am debugging the target XC164CS on the Infineon evaluation board using the serial interface with the Keil 166 driver. The debugger hangs after i try to initialize the Vector Segment register. The initialization being done after the control is transferred to the application after the StartUp code of Keil. Could anyone please help me find a way through this? Thanks and Regards, Prakash
