Hi, At this time I get "error 65: access violation.." when the sw jumps into bank 0 in a banked application using uVision2 simulator. The bank number is set by SFR called MEX1 at address 0x94. I would like to know whether the Simulator in uVision2 supports code banking. If yes, can anyone tell me how to setup the simulator in order to be able to run cvode from different banks? Thanx. ZB
