Definition An external
programmer or
processor
programs the
device mounted on
the board
System controller
programs a blank
device when the
flash golden pin is
asserted at device
power up
Cortex-M3 in the
MSS fetches the
bitstream from
outside the chip
and calls ISP
system service,
which programs
the FPGA
Cortex-M3 or user
logic programs the
bitstream into the
SPI flash
connected to
SPI_0 port and
calls IAP service
call, which
programs the
FPGA
A standalone
programmer or test
equipment
programs the
FPGA before it is
surface mount
using an adapter
module or a test
fixture

Not applicable Address 0x00
location of the

Not applicable SPI directory
defines where the
update and/or
golden image is
located. Both
images have to be
in non-zero
address location,
as address zero is
reserved for SPI
directory.
Not applicable
SPI directory Not applicable Not needed Not applicable You must export
SPI directory while
exporting the
bitstream and
program it into the
external flash
device in the
address zero
location.
