The GSRD release includes a web server running on the target board that can be used to exercise some of the board's features:
  • Displaying text on the alphanumerical LCD screen
  • Turning LEDs ON and OFF
  • Scrolling LEDs in a sequence
  • Displaying the current status of the LEDs.
The webpage served by the web server also contains links to some relevant information on the Altera website.

Note that the screenshots presented in this page are taken using the Arria 10 Development board.

Connect to Web Server

1. Boot GSRD Linux release as described in the Booting Linux.

2. Write down the IP address displayed on the first line of the LCD screen. Note that the IP address is displayed only at the boot time, it is not updated if the IP address is changed later, for example by the user.

Note: There are instances where the DHCP have not assigned an IP to the board before the timeout happens, in which case you may check the ip address via the UART by running ifconfig

 root@arria10:~# ifconfig 

3. Open a web browser on the host PC and type http://<target_ip_address> on the address box and hit Enter.

Board Features

4. You can hover with the mouse over the board image on the browser, and it will highlight different features.

You will be able to perform the following actions:
  • See which LEDs are ON and which are OFF in the LED Status image. Note that if the LEDs are setup to be scrolling, the displayed scrolling speed will not match the actual scrolling speed on the board.
  • Stop LEDs from scrollig, by clicking START or STOP buttons. The delay between LEDs turning ON and OFF is set in the LED Lightshow box.
  • Turn individual LEDs ON and OFF witht the ON and OFF buttons. Note that this action is only available when the LED scrolling/lightshow is stopped.
  • Blink individual LEDs by typing a delay value in ms then clicking the corresponding BLINK button. Note that this action is only available when the LED scrolling/lightshow is stopped.
  • Display text to the alphanumerical LCD Display, by typing the text in the Send to character LCD the pressing the Send to LCD button. Note that the text is displayed in the 2nd LCD line, and it is limited to 16 characters.
