directory and simply execute it to load NuttX onto the board (after
entering ISP mode).
Here are the detailed steps I use:
1. Make sure you exit minicom (or whatever terminal emulator you are

2. On the MCU123 board, I need to put a jumper on JP3-INT. On that board,
JP3-INT is connected to P0.14 of LPC214x. When P0.14 is low and RTS is
changed from high to low, the LPC214x will enter ISP (In System Programming)
state.
