The
256
KByte
recovery
boot
image
is
stored
in
a
hardware
write
‐
protected
Flash
sector.
This
is
factory
programmed
and
its
contents
cannot
be
overwritten
by
a
user.
4.4 P12 Header
This
header
is
multi
‐
functional
and
allows
for
firmware
reprogramming,
factory
JTAG
testing
and
AMP/SMP
selection.
Users
generally
should
not
need
to
adjust
the
factory
default
link
settings
for
JTAG
aspects
of
this
header.
They
are
set
to
allow
firmware
reprogramming
of
the
FPGA/CPLD,
which
is
the
most
likely
JTAG
operation
to
be
performed
by
a
user.
However,
it
is
important
that
a
user
sets
the
AMP/SMP
jumper
correctly
for
their
intended
operation.
AMP
mode
is
the
favored
operational
mode,
which
requires
P12
pins
1
and
2
to
be
linked.
