I don&#39;t see any reason why the SysID peripheral would have anything to do with it (I suggest you keep it in your design to make sure you are using the correct hardware). One thing to make sure of is that you have the correct name of the custom instruction (in your case " ALT_CT_BSWAP(a)"). If the C compile occured with no errors then this wouldn&#39;t be the cause.

Can you describe further what you are seeing and how you set up the custom instruction?
