I compile successfull the last code, but i was not able to see anything on serial port 0 of CS5535. But something is clear for me now: if you don't have VSA initialized, you aren't able for using serial port of companion chip. As a matter of fact, you are probably sending the bytes to port 0 of winbond super i/o, isn' t ? Are you really sending the debug output for port 0 of WINBOND 87364 ?
