4. Configuration

4.1 Jumper Settings

Please see Figures 2-3 and 2-4 in Chapter 2 to view the positions of the jumpers and

resistors on the board.

4.1.1 Bootstrap Loader / Socket Jumper J1

The Jumper J1 is used to select the memory position from which the VMP1 fetches its

boot code. It determines the address position of the onboard Flash window and the

Flash/SRAM expansion socket (DIL600, 32-pin).

Note: The MPC8240 initially fetches its boot code from address 0xFFF0 0100!

4.1.2 RTC (Real-time clock) Calibration Output J2

Frequency test output is used for calibration of the onboard RTC. The RTC provides a

512 Hz frequency test signal for calibration purposes. Please refer to the datasheet of

the ST M41T56 for detailed information (for position of J2 on the board please see figure

2-3).
