CONFIG_UART1_2STOP=0
In this configuration using UART1, it is necessary to disable LED support
on the board. That is because UART1 RXD is set for pin p0.16, but so it
on the board. That is because UART1 RXD is set for pin p0.16, but so is
LED2. If you do not disable LED support then no incoming serial data will
be recevied.

CONFIG_ARCH_LEDS=n : Disable LED support
You should also remove the LED2 jumper so that the RXD input does not
attempt to drive LED2 as well (this this does not seem to interfere with
attempt to drive LED2 as well (However, this does not seem to interfere with
data receipt).
NOTE: If you intend to use LEDs, then you might want to redesign some of
the LED logic in the src/ subdirectory so that it does not use LED2.
