3.1.3 Connect Development Platform to PC; Run Preloaded Image

Figure 3-4 illustrates the switches and PC connection.

To connect the 3-Stack platform to your host PC, use these steps:

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 the following table.
