--------------
The LPC1766-STK board has two serial connectors. One, RS232_0, connects to
the LPC1766 USART0. This is the DB-9 connector next to the power connector.
The other RS232_1, connect to the LPC1766 USART1. This is he DB-9 connector
the LPC1766 UART0. This is the DB-9 connector next to the power connector.
The other RS232_1, connect to the LPC1766 UART1. This is he DB-9 connector
next to the Ethernet connector.
Simple USART1 is the more flexible USART and since the needs for a serial
console are minimal, the more minimal USART0/RS232_0 is used for the NuttX
Simple UART1 is the more flexible UART and since the needs for a serial
console are minimal, the more minimal UART0/RS232_0 is used for the NuttX
system console. Of course, this can be changed by editting the NuttX
configuration file as discussed below.
The serial console is configured as follows (57600 8N1):
BAUD: 57600
Number of Bits: 8
Parity: None
Stop bits: 1
You will need to connect a monitor program (Hyperterminal, Tera Term,
minicom, whatever) to UART0/RS232_0 and configure the serial port as
shown above.
NOTE: The ostest example works fine at 115200, but the other configurations
have problems at that rate (probably because they use the interrupt driven
serial driver). Other LPC17xx boards with the same clocking will run at
115200.

OpenOCD will support several special 'monitor' commands. These
GDB commands will send comments to the OpenOCD monitor. Here
are a couple that you will need to use:
(gdb) monitor reset
(gdb) monitor halt
The MCU must be halted prior to loading code. Reset will restart
the processor after loading code. The 'monitor' command can be
abbreviated as just 'mon'.
