This project is intended to demonstrate the capabilities of the `Chips-2.0 `_ development environment. The project is targets the Xilinx Spartan 6 device, and more specifically, the Digilent ATLYS development platform. The demo implements a TCP/IP socket interface, and a simple web application. So far the demonstration has been tested on a Ubuntu Linux only.

Connect the Ethernet port to ATLYS, using a crossed over Ethernet cable (which comes with the development kit).
|
| 77 |
|
|
|
| 78 |
|
|
Using the script, configure Ethernet port with IP address 192.168.1.0 and subnet mask 255.255.255.0. Turn off TCP Window Scaling and TCP time stamps::
|
| 79 |
|
|
|
| 80 |
|
|
$ ./configure_network
|
| 81 |
|
|
|
| 82 |

|
| 83 |
|
|
|
| 84 |
|
|
$ ping 192.168.1.1
|
| 85 |
|
