Honored ContributorI had this problem too when debugging my master port. You have to make sure you wait for the 'waitrequest' signal to go inactive before releasing the 'read' signal. You can release the 'read' signal on the next clk edge after 'waitrequest' goes inactive -- assuming you're using a synchronous interface.
Your description made it sound like you were performing a write to MAC, but the error is on the 'read' signal. Be sure the 'read' signal is in a known state. Good luck! Jon
