Ethernet About Remote System Update
In the previous example the FPGA was configured from designs stored
on the SD Card. But imagine you are working at your desk and your
system is physically located elsewhere (such as in the lab or
manufacturing facility or even a customer site). Having remote
reconfiguration capability in your FPGA allows you to update your
system with a new FPGA image so long as there is a persistent Ethernet
connection.
The way this works is that when your kit is connected to a network, it
serves up a web page. The contents of this web page are stored in the SD
Card in a folder entitled
webserver_html . From any PC, you can view
this web page by simply typing the correct IP address on a web browser.
By following the instructions displayed on the HTTP forms on the web
page you can browse to and load a design stored on the local PC and
program it to the flash on your board. You can then reset the FPGA on
your board and the FPGA should reconfigure from the newly
downloaded Flash image.
