Question: What does the message " Cannot acquire EMU0/EMU1 lines " mean in a multiprocessing debugging environment ?

Answer: This usually happens when trying to use "runb " simultaneously in different processors

Our emulator supports "runb" only IN ONE PROCESSOR AT A TIME (because it uses EMU0/EMU1 pins that are connected together in a multiprocessing configuration)

Solution :
Use runb only in one processor at a time
