The default interface is UART3 and the selection table is shown in
UART3 vs SPI[2]
UART3 and SPI[2]
Use Bit "P16" in I2C IO Expander (U57) with slave address 0x0100 0010(Write) to control, signal
"SEL_UART3_SPI2".
3.4.10 UART1 vs UART3
Upon selection of UART3, it has been multiplexed with UART1 and then connected to FT232RQ UART to
the USB converter for the USB console. GPIO expander selection can be override by available manual
switch on board. The corresponding image is shown in
table is shown in Table
UART1 vs UART3
UART3 and SPI[2]
Use bit "P14" in I2C IO Expander (U57) with slave address 0x0100 0010(Write) to control, signal
"UART_SEL1_3". A DIP switch is also available to control the UART_SEL1_3 signal for boot mode
configuration.
