STi5528 Eval (mb376)
This board was designed primarily for silicon validation. As such the chip
is socketed, and there is a large number of connectors to enable all the features
of the chip to be used.

| RS232 ASC0 | CN37 (bottom) | ASC | ASC3 | /dev/ttyAS0 | Special cable |
| RS232 ASC1 | CN37 (top) | ASC | ASC4 | /dev/ttyAS1 | Special cable |
| RS232 SCIF0 | CN38 (top) | SCIF | SCIF1 | /dev/ttySC0 | Null modem |
| RS232 SCIF1 | CN38 (bottom) | SCIF | SCIF2 | /dev/ttySC1 | Null modem |
To use the ASC ports it is necessary to construct a special cable, as RX and TX are the wrong way round for the gender of
the connector.
