Note
A crossover cable is not required in any network configuration. The
network PHY includes Auto MDI/MDIX, which will automatically adjust
to make link over both crossover and straight-through cable types.
Most development boards include two serial ports. UART0 serial is routed
to the USB port and to the DB9 connector labeled UART0. UART1 is
routed only to the DB9 connector labeled UART1. The default mode for
UART0 serial is through the USB port. To change the default mode, set
the specified jumpers below to the desired position.
