configuration in that this configuration, like the usbnsh
configuration, it uses a USB serial device for console I/O.
Such a configuration is useful on the Clicker2 STM32 which
has no builtin RS-232 drivers and tangle of cables and jumpers
needed to debug multi-board setups.

connection will be lost when the target board is reset. When that
happens, you may have to reset your serial terminal program to adapt
to the new USB connection. Using TeraTerm, I actually have to exit
the serial program and restart it in order to detect and select the
re-established USB serial connection.

configuration supports logging of debug output to a circular
buffer in RAM. This feature is discussed fully in this Wiki page: http://nuttx.org/doku.php?id=wiki:howtos:syslog . Relevant
