Serial Console
==============
Two UART connections are available:
1. UART0 is available on J5 Debug Port.
UART0 is available on J5 Debug Port.
UART2 is available on J11
J15 Pin 1 Rx UART0-RX UART0_RX/IR1_RX/PB23
J15 Pin 2 Tx UART0-TX UART0_TX/IR1_TX/PB22
2. UART2 is available on J11
J11 Pin1 UART-Rx / GPIO0 UART2_RX EINT31/SPI1_MISO/UART2_RX/PI19
J11 Pin2 UART-Tx / GPIO1 UART2_TX EINT30/SPI1_MOSI/UART2_TX/PI18
By default, the serial console will be provided on UART0 in all of these
configurations.
