JP1 is used to boot on standard or user programs. For standard operations, set it in the
STD position.
JP8 is used to select the core power supply of the AT91M55800A. Operations at 2V are
not supported on the current silicon.
For more information about jumpers and other straps, see Appendix A.
DC power is supplied to the board via the 2.1 mm socket (J1) shown below in Figure 2-
2. The polarity of the power supply is not critical. The minimum voltage required is 7V.
Figure 2-2. 2.1 mm Socket
The board has a voltage regulator providing +3.3V. The regulator allows the input volt-
age to be from 7V to 12V. When you switch the power on, the red LED marked
“POWER” will light up. If it does not, switch off and check the power supply connections.
The battery BT1 provides a 3V power supply to the Advanced Power Management Con-
troller and the Real Time Clock (V

In order to test the AT91EB55 Evaluation board, the following procedure should be
performed:
1. Hold down the SW1 button and power up the board or generate a reset and wait
2. Release the SW1 button. The LEDs D1 to D7 light up in sequential order. If an
