*** LED2 may also flicker normally if signals are processed.
Serial Console
^^^^^^^^^^^^^^
By default, all of these configurations use UART0 for the NuttX serial
console. UART0 corresponds to the DB-9 connector labelled "UART". This
is a male connector and will require a female-to-female, NUL modem cable
to connect to a PC.
An alternate is USART1 which connects to the other DB-9 connector labeled
"USART". USART1 is not enabled by default unless specifically noted
otherwise in the configuration description. A NUL modem cable must be
used with the port as well.
NOTE: One of the USART1 pins is shared with the audio CODEC. The audio
CODEC cannot be used of USART1 is enabled.
By default serial console is configured for 115000, 8-bit, 1 stop bit, and
no parity.
