Zynq-based WISER platform - Start-up test

Description

This tutorial shows how to load the Zynq-based WISER platform (Zedboard + ADFMCOMMS1) on ORBIT and run a start-up test.

Hardware / Software Resources utilized

1. An SB6 node with WISER platform connected to it.
2. wiser_sb6_zedboard.ndz: disk image.

Set up

• To get started first make a reservation on the ​Orbit Scheduler for using the SB6.

• After logging into SB6 console, image one of the nodes

  omf load -i wiser_sb6_zedboard.ndz -t node1-1
  

• Once imaging is done, turn the node on

  omf tell -a on -t node1-1
  

• Wait for the node to turn on and log in

  ssh root@node1-1
  

Loading the Zedboard

Download ELF file to be run on the ARM core.

Open another terminal and run the startup shell script, which configures the Ethernet interface that connects to Zedboard, and starts DHCP server on the node.

In the same terminal launch minicom to listen to the serial data sent by Zedboard.

Running a start up test

At the XMD prompt, start the processor by typing "con"

The following would be printed out in the minicom window.
