Quickstart: Just the Board ============================= This page runs through the steps of configuring a "bare" Novena mainboard for use as a display-less system using the factory-installed microSD card as the rootfs media. .. figure:: /img/novena-unbox-board-pvt2a.jpg :align: center :alt: Novena PVT2 just-the-board unboxing, Dec 2014 :width: 100% :target: _images/novena-unbox-board-pvt2a.jpg *Novena PVT2 "Just-The-Board" contents (December 2014)* .. topic:: Before you begin... You will need a 3.3V USB-FTDI cable and a computer to work from (as a terminal). You will also need an Ethernet cable if you want wired networking. First, before applying power, attach the FTDI cable with the USB side connected to your host machine and the UART end connected to the Novena. The correct UART connection is described on the `"Using Novena PVT1" wiki page `_, and is shown below. .. TODO:: better image of attached cable .. figure:: /img/novena-uart-console-pvt2-photo.jpg :align: center :alt: Novena UART Console Cable (PVT2) :width: 100% :target: _images/novena-uart-console-pvt2-photo.jpg *Novena PVT2 board with FTDI UART cable attached to console port (note wire colors and orientation)* .. figure:: /img/novena-uart-pinout.jpg :align: center :alt: Novena UART Pinout (PVT2) :width: 100% :target: _images/novena-uart-pinout.jpg *Pinout of Novena PVT2 board console port, wire colors correspond to default FTDI UART connector* Open a terminal program on the work machine and open the FTDI device using 115200 baud as the speed and "normal" settings for everything else (eg, ``8n1``). For example, on a UNIX machine you could use the ``screen`` command line program:: screen /dev/ttyUSB0 115200 # Should be a blank screen until the Novena boots. # Type "Ctrl-A" then "k" to quit when you are done. Or you could use minicom or GtkTerm or whatever your favorite is.. Finally, connect power to the Novena board's DC barrel jack. You should see u-boot and then kernel boot messages stream out the console. Eventually you will enter the `"first run" menu system `_, which was created by ``xobs`` specifically for the Novena. You should be able to make reasonable selections for yourself by reading the prompts; a US-centric set of defaults for a headless (aka, no display) system might be: - "Configuring console-data": select "Don't touch keymap" - "Configuring locales": "en_US.UTF-8 UTF-8" or yours - "Configuring locales": the locale you selected - "Configuring tzdata": your region, or "none of the above" to get to UTC - Enter a new root password - Create a user account - Choose a hostname or accept the autogenerated one - Disable graphical logins Following all the prompts, the system should get configured and you will be able to login as the user you created. Blessed be! The next step will be to get networking up and running so you can upgrade and/or install new software. .. note:: You need a wired connection to install required utilities before you can configure the wireless interfaces. **Configure Ethernet Networking** Attach ethernet cable to a switch/router to the left-hand port (eth0). If DHCP is enabled on the local network, the interface should be configured automatically. Test the connection with:: sudo ifconfig eth0 sudo ping www.mit.edu **Configure WiFi Networking** .. warning:: The below isn't really a great way of doing things (and hasn't actually been confirmed to work), it's just a quick way to test. .. TODO:: closed wifi hotspot, passwords Install packages (over the wired connection):: sudo apt-get install wireless-tools iw Connect to an open network named, eg, "31C3-open-legacy":: sudo iw dev wlan0 connect 31C3-open-legacy sudo dhclient wlan0 **After networking is configured** Once networking is going, you should definately update the ``apt`` package database, and you may wish to upgrade all existing packages (from the factory image) to the most recent available versions. The default configured debian mirror (to download updates from) is in the United States. You might want to change the ``/etc/apt/sources.list`` file to point to something closer; changing to ``http.debian.net`` will auto-select a good mirror wherever you are in the world. To update package information, a process which should run reasonably fast even the first time:: sudo apt-get update The ``upgrade`` step could take 30+ minutes all together, even given a fast connection, because disk I/O operations on the built-in microSD card are very slow. Don't start this process until you are patient enough to let it finish without interruption. You don't really need to do the ``upgrade`` up front before you start experimenting, it's just a good idea to stay patched with bug fixes and security updates. To upgrade all packages with new versions, run:: sudo apt-get upgrade You may encounter a dpkg problem with the dbus package ("Package libdbus-1-3:armhf is not configured yet."). If this happens run ``sudo apt-get install -f`` to fix configuration, then ``sudo apt-get upgrade`` to finish the upgrade. You will almost certainly find youself needing i2c control utilities if you will be hacking on the Novena, eg to compile the FPGA userland tools, so now would be a good time to do:: sudo apt-get install i2c-tools libi2c-dev
