NOTE: If you enable the I/O1 this configuration with USART0 as the
console and with the I/O1 module in EXT1, you *must* remove UART
jumper. Otherwise, you have lookpack on USART0 and NSH will *not*
behave very well (since its outgoing prompts also appear as incoming
commands).

NOTE: If you get a compilation error like:
Sometimes NuttX and your toolchain will disagree on the underlying
type of size_t; sometimes it is an 'unsigned int' and sometimes it is
an 'unsigned long int'. If this error occurs, then you may need to
toggle the value of CONFIG_CXX_NEWLONG.

1. If the LCD1 module is connected to the SAM4L Xplained Pro, then
support for the SLCDt can be enabled by making the following
