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.
