To connect the 3-Stack platform to your host PC:
1. Connect one end of an RS-232 serial cable (included in the kit) to a serial port
connector (CON4) on the Debug board and connect the other end to a COM port on the
host PC.
• Configure SW4-1 to ON.
• Make sure that SW4-8 is ON, to supply power to all three boards.
• Configure SW4-2 to OFF.
2. Confirm that the Bootstrap switches (SW5–SW10) are set for NAND boot. See
