6 Configuring the hardware for startup

Figure 18. Typical initial configuration

Figure 18 presents a typical hardware configuration incorporating the development

board, power supply and Windows PC workstation.

To configure the hardware and workstation as illustrated in Figure 18, complete the

following procedure:

1. Install jumpers for the configuration.

Table 16. Jumper configuration

Jumper Configuration

J24 connect 1-2 (connect 5.0 V on DBG pin from the USB)

Table 17. Switch configuration

Switch Configuration

SW1 middle position (VBAT off)

SW2 open (WAKE1)

SW3 open (OTP programming off)

3. Connect the Windows PC USB port to the KITFS85AEEVM development board using

the provided USB 2.0 cable.

Set the DC power supply to 12 V and current limit to 1.0 A. With power turned off,

attach the DC power supply positive and negative output to KITFS85AEEVM V

BAT

Phoenix connector (J1).

4. Turn on the power supply.

5. Close SW2.

Note: At this step, the product is in debug mode and all regulators are turned off. The

user can then power up with OTP configuration or configure the mirror registers before

power up. Power up is effective as soon as J24 jumper is removed.
