How to develop ADI Yocto Linux with your own repositories

This documentation guides users how to develop Yocto Linux Products on ADI SC5XX platforms with developers' own repositories. 

HOST Setup

$ sudo apt-get update
$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat libsdl1.2-dev xterm u-boot-tools
$ sudo apt-get install repo

Source Code Preparation

Download Source code

$ mkdir ~/yocto
$ repo init -u -b release/yocto-1.0.0

Change lnxdsp-adi-meta and lnxdsp-scripts to point to your own repo

$ cd ~/yocto/.repo/manifests/

Aplly below patches into the lnxdsp-repo-manifest

$ repo sync

Change u-boot and linux-kernel URI to point to your own repo

$ cd ~/yocto/sources/

Aplly below patches into your own build script, take adsp-sc589-ezkit as an example, the same patch should be applied into adsp-sc589-mini, adsp-sc584-ezkit, adsp-sc573-ezkit.

diff --git a/base/adsp-sc589-ezkit/local.conf b/base/adsp-sc589-ezkit/local.conf

Then you can start your development based on your own repos.

$ cd ~/yocto/
$ source setup-environment -m adsp-sc589-ezkit
Your build environment has been configured with:


You can now run 'bitbake <target>'
Some of common targets are:

$ bitbake ...
