Procedure for Rev3 Boards
To determine if the board is a Rev3 board:
A Rev3 Board is recognized by examining the front of the board and looking for the part number just beneath the large
Actel corporate logo on the board top silk-screen. The part number will be A3PE-A3P-EVAL-BRD1 followed by
REV3.
To chain Rev3 boards together:
All boards from the board nearest the FlashPro3 programmer should have the shunt that is placed by default on pins 3
and 4 of the J5 header moved to connect pins 1 and 2. On the board and schematic this is labeled quite clearly as
CHAIN (pins 1 and 2) and LAST DEVICE (DEFAULT) (pins 3 and 4). Only the very last board in the chain
should have the shunt remaining across pins 3 and 4 of the J5 connector.
Note that if there is only one board in the chain then it, by definition, is the last board and should have the shunt at J5
connecting pins 3 and 4. This is why this position is labeled as the DEFAULT position for a typical customer with a
single starter kit board.
Procedure for Rev2 Boards, With and Without Rework
To determine if the board is a Rev2 board:
A Rev2 board is indicated by a red power LED in the upper right corner of the board and a part number underneath the
Actel corporate logo on the board top silk-screen. The part number will be “A3PE-A3P-EVAL-BRD1”. No additional
text will follow the board number. If the board has been reworked to force it to become equivalent to a Rev3 board, it will
contain a green wire on the top side of the board. If it does not contain green wire, it is an original Rev2.
To chain Rev2 boards together:
If reworked, treat it as Rev3 in the previous section. If not reworked, then chaining of the boards cannot be done. The
shunt on J5 must be removed for any programming to take place.
Procedure for Rev1 Boards
To determine if the board is a Rev1 board:
A Rev1 Board is indicated by no red power LED in the upper right corner of the board. The part number on the board
top silk-screen is A3PE-EVAL-BRD600.
Note:
V
When these boards are connected via a connection from J2 of one board to J1 of another board, V
connected from one board to another. When powering on one board with a connector in place, notice that the 1.5 V, 1.8
V, 2.5 V, and 3.3 V LEDs will light on the board to which no power has been applied. The FPGA on that board, if it is
programmed, will start operating. This is clearly an inappropriate situation for a large chain of boards. This is caused by
having the JP48 connector for supplying V
itself connected to the 3.3 V supply output that is used to generate the other FPGA voltages on a board. To prevent
V
connector to force JP48 to be open-circuit. To prevent loss of the shunt, it may be safely stored on the J12 header for the
daughter card power supply as it is impossible to cause a short by joining any adjacent pins.

Rev1 boards should not be used with this tutorial guide or with design files included with this Starter Kit as the
schematics are incompatible with current commercial boards.
