Layer to Support the Terasic DE10-Nano* Board

Overview

Instructions to build the image for the Terasic DE10-Nano* development board and then write that image to a microSD card.

This layer provides support for building a demonstration and development image of Linux* for the Terasic DE10-Nano kit's development board.

Build Instructions

Please refer to README.md for any prerequisites. These instructions assume prerequisites have been met.

Note: See the instructions for configuring proxies.

Steps to build the image:

  1. Clone the manifest.
  2. Add the meta-de10-nano layer.
  3. Fetch repositories.
  4. Build the image.

Step 1: Clone the Manifest

Clone the manifest to get all required recipes for building the image.

mkdir de10-nano-build
cd de10-nano-build
repo init -u git://github.com/Angstrom-distribution/angstrom-manifest -b angstrom-v2016.12-yocto2.2 

Step 2: Add the meta-de10-nano Layer

The default manifests do not include the meta-de10-layer. Therefore, we add the layer and resolve any issues encountered with errant layers.

mkdir .repo/local_manifests

Now we create the manifest to add the meta-de10-layer. The following will create .repo/local_manifests/de10-nano.xml. This specifies a specific revision for meta-altera and meta-de10-nano.

cat << EOF > .repo/local_manifests/de10-nano.xml
<?xml version="1.0" encoding="UTF-8"?>                                          
<manifest>                                                                      
        <remove-project name="kraj/meta-altera" />                              
        <remove-project name="koenkooi/meta-photography" />                     
        <remove-project name="openembedded/meta-linaro" />                      
        <project name="openembedded/meta-linaro" path="layers/meta-linaro" remote="linaro" revision="992eaa0a1969c2056a5321c122eaa8cd808c1c82" upstream="master"/>
        <project remote="github"  name="kraj/meta-altera" path="layers/meta-altera" revision="cf7fc462cc6a5e82f2de76bb21e09675be7ae316"/>
        <project name="01org/meta-de10-nano" path="layers/meta-de10-nano" remote="github" revision="refs/tags/VERSION-2017.03.31"/>
</manifest> 
EOF

The above also disables meta-photography, so we have to edit conf/bblayers.conf to remove the reference to it.

sed -i '/meta-photography/d' .repo/manifests/conf/bblayers.conf

We also need to add in the new meta-de10-nano layer to the bblayers.conf

sed -i '/meta-altera/a \ \ \$\{TOPDIR\}\/layers\/meta-de10-nano \\' .repo/manifests/conf/bblayers.conf

Step 3: Fetch the Repositories from the Manifest

repo sync

Step 4: Build the Image

Estimated to complete: 2–3 hours.

MACHINE=de10-nano . ./setup-environment
bitbake de10-nano-image

After Building the Image

The result of this lengthy build is an image that can be written to an SD card which will enable the Terasic DE10-Nano board to boot Linux*. The image provides access via serial port, a graphical interface, USB, and Ethernet. As part of the build, the recipes populate an FPGA image as well as the associated device trees.

The build output is located in deploy/glibc/images/de10-nano/

The SD card image name in the above list is "Angstrom-de10-nano-image-glibc-ipk-v2016.12-de10-nano.rootfs.socfpga-sdimg".

Note: prebuilt images can be found here.

Write the Image to a MicroSD Card

These instructions only cover Linux*, for alternate instructions please go here.

Caution: These instructions use the dd command which should be used with EXTREME CAUTION. It is very easy to accidentally overwrite the wrong device which can lead to data loss as well as hours spent rebuilding your machine.

The first step is to insert the SD Card using either a dedicated SD Card interface or a USB adapter into your machine. Discover which device this shows up. Usually the device shows up as /dev/sdX or /dev/mmcblkX where X is the device number. As an example, our dedicated SD Card interface shows up as /dev/mmcblk0.

Note: for safety reasons these instructions will use /dev/mmcblkX as this should never be a real device.

It will take a few minutes to write the image (~2GB).

cd deploy/glibc/images/de10-nano/
sudo dd if=Angstrom-de10-nano-image-glibc-ipk-v2016.12-de10-nano.rootfs.socfpga-sdimg of=/dev/mmxblkX bs=1M && sync && sync

After this completes, insert the microSD card into the DE10-Nano board and then power it on.
