Setting the Flash Memory Bank A/Bank B Reset Vector Header (J15)
Bank B consists of 1 MB of 8-bit Flash memory in two 32-pin PLCC
8-bit sockets.
Bank A consists of four 16-bit Smart Voltage SMT devices that can
be populated with 8Mbit Flash devices (4 MB) or 4Mbit Flash
devices (2 MB). A jumper header, J15, associated with the first set of
four Flash devices provides a total of 64KB of hardware-protected
boot block. Only 32-bit writes are supported for this bank of Flash.
The address of the reset vector is jumper-selectable. A jumper must
be installed either between J15 pins 1 and 2 for Bank A factory
configuration, or between J15 pins 2 and 3 for Bank B. When the
jumper is installed, the Falcon chipset maps 0xFFF00100 to the Bank
B sockets..
Setting the VMEbus System Controller Selection Header (J16)
The MVME230
x
is factory-configured in automatic system
controller mode; i.e., a jumper is installed across pins 2 and 3 of
header J16. This means that the MVME230
x
determines if it is
system controller at system power-up or reset by its position on the
bus; if it is in slot 1 on the VME system, it configures itself as the
system controller.
Remove the jumper from J16if you intend to operate the
MVME230
x
as system controller in all cases.
Install the jumper across pins 1 and 2 if the MVME230
x
is not to
operate as system controller under any circumstances.
