The EVM supports a dual UART connection to be used for the user terminal. A FT2232 device transports the UART information over USB to a host PC. The EVM is designed to use UART1 of the SoC as the primary terminal connection, and is connected to port A of the USART transceiver. The USB-side of the FT2232 device is powered from the USB port, and the connection stays active regardless of the power state of the EVM. The green LED (D1) indicates that the USB connection is available.
A USB cable (mini-B to type A) connects the EVM to a PC, and is included as part of the EVM kit.
The EVM can support a second UART connection to the FT2232 device, intended for booting. However, this configuration requires board modifications, and is recommended only for specific users.
