Building Software Defined Radio (SDR) systems based on meta-sdr

This repository provides git submodules to setup the OpenEmbedded build system with meta-sdr and possibly one or more BSP's (based on the branch you select).

OpenEmbedded allows the creation of custom linux distributions for embedded systems. It is a collection of git repositories known as layers each of which provides recipes to build software packages as well as configuration information.

Information about the branch names is available at https://wiki.yoctoproject.org/wiki/Releases. Helpful articles about working with GNUradio and Openembedded are at: http://www.opensdr.com/categories/.

Getting Started

1. Clone the git repository:

   $ git clone https://github.com/balister/sdr-build.git

2. Check out the appropriate branch:

   $ cd sdr-build $ git checkout -b master-qemu origin/master-qemu

3. Update the submodules:

   $ git submodule update --init

4. Initialize the build system:

   $ TEMPLATECONF=`pwd`/meta-sdr/conf/templates/default source ./openembedded-core/oe-init-build-env ./build ./bitbake

5. Select the MACHINE to build for:

   $ export MACHINE=qemux86-64 (default from local.conf)

6. Build an image:

   $ bitbake gnuradio-dev-image

7. Build another image:

   $ bitbake gnuradio-demo-image

8. Build and sdk:

   $ bitbake -c populate_sdk gnuradio-dev-image
