USART2 is enabled in most configurations (see */defconfig). RX and TX are
configured on pins PA3 and PA2, respectively (see include/board.h).
These pins selections, however, conflict with Ethernet pin usage on the
STM32F4DIS-BB base board. The STM32F4DIS-BB base board provides RS-232
drivers and a DB9 connector for USART6. USART6 is the preferred serial
console for use with the STM32F4DIS-BB.
