Description
Add support for writing
configuration parameters
—
Enable this if you need to write configuration
parameters.
Enable reconfig POF
checking
—
Allows you to enable .pof checking, which allows the
remote update block to verify the existence of an
application configuration image before the image is
loaded. When you turn on this parameter, the Altera
Remote Update IP core checks the .pof and sends the
reconfig
signal. This option is disabled by default.
POF checking feature detect and verify the existence of an application configuration image before the
image is loaded. Loading an invalid application configuration image may lead to unexpected behaviour of
the FPGA including system failure. Example of invalid application configuration images are:
• A partially programmed application image
• A blank application image
• An application image assigned with a wrong start address

Description
read_param
Input
No
Read signal for the parameter specified in
param[]
input port and fed to
data_out[]
output port.
Signal indicating the parameter specified on the
param[]
port should be read. The number of bits
set on
data_out[]
depends on the parameter
type. The signal is sampled at the rising clock
edge. Assert the signal for only one clock cycle to
prevent the parameter from being read again in a
subsequent clock cycle.
The busy signal is activated as soon as
read_
param
is read as active. While the parameter is
being read, the busy signal remains asserted, and
data_out[]
has invalid data. When the busy
signal is deactivated,
data_out[]
is valid,
another parameter can be read.
