SPI directory Not applicable You must
export SPI
directory while
exporting
bitstream and
program it into
the external
flash device in
address zero
location.

System
controller reads
the SPI
directory for the
image version.
Every time a
new image is
programmed,
you need to
export SPI
directory (by
setting
appropriate
design version
and/or address)
and program
the flash device
before initiating
auto update.
Not applicable You must

recovery
support
Not supported Not supported
since the
device is blank
(recovery bit
has not been
programmed
into the device)
Supported. If
you turn on the
auto update
switch in Libero
SoC, recovery
is turned on by
default. If power
fails, the
system
controller uses
the golden
image defined
in the SPI
directory.
Supported.
First, the FPGA
needs to be
programmed
with recovery
setting enabled
in Libero SoC.
