@ gmpstr : interseting. Maybe the resolved type "std_logic_vector" is not good for inout. The unresolved "std_ulogic_vector" could be good

@asickrishna :

In a Nios II command Shell (see Windows start menu/programs/altera/... or "C:\altera\12.0sp1\nios2eds\Nios II Command Shell.bat" )

nios2-flash-programmer --debug --base=0x10800000

You will get something like this
