Getting the DE1-SoC up and running

V. Hunter Adams

Note: This is mostly an abridged version of the Linux on HPS webpage with the parts omitted that will not be relevant for this semester.

Setting up the hardware

  1. Acquire a DE1-SoC from Hunter.
  2. Hook up the hardware: For most exercises there will be 5 or six connections to the board: serial, ethernet, VGA, audio (for lab 2), USB blaster, power. See the image below.

  3. Acquire a micro-SD card from Hunter.
  4. Load this Linux image onto the SD card.
    • If you are working with a windows machine, The sections 2.1 and 2.2 Using Linux on the DE1-SoC shows how to install Linux on an SDcard.
    • If you are on a Mac, use something like ApplePiBaker.
  5. Open a serial connection to the DE1 (don't boot it yet). Use baud 115200.
  6. Insert the SD card into the DE1.
  7. Boot it. You will see a bunch of text scroll past on the serial terminal.

Configuring the Linux environment

  1. The Cornell 10space system will be used for any FPGA on the internet in the lab.
    • The Cornell 10space system is not reachable from wireless devices!
    • The MAC address and IP address are locked down and must match.
    • You will use a static address assigned to your group. You may not use another group's addresses.
  2. YOU MUST CHANGE YOUR MAC AND IP ADDRESSES. Ask Hunter for your group's MAC/IP addresses. They will be of the following form:
    • IP: 10.253.17.xx
    • MAC: 12:34:56:78:90:yy
  3. Write these down!! These are sacred to your group.
  4. From the serial command line, navigate to /etc/network/interfaces and open it using a command-line editor. It will look like this:
    auto eth0 iface eth0 inet static hwaddress ether 12:34:56:78:90:yy address 10.253.17.xx netmask 255.255.255.0 gateway 10.253.17.1 dns-nameservers 132.236.56.250 128.253.180.2 192.35.82.50
  5. Modify the address and hwaddress to match your group's assigned IP and MAC addresses.
  6. Save, then run /etc/init.d/networking restart.
    • If you get a eth0 error, then run reboot

Secure Shell Login

  1. From a Lab PC (or your own PC if you've VPN'd onto the Cornell network), open an ssh connection to root@10.253.17.xx (where xx is your group's assigned IP).
  2. The default root password is bigred5760
  3. Change this password using passwd!!

Going further

  1. Read the Linux on HPS page to learn how to move files to/from the HPS, and how to compile/run C using GCC.
