Where:
* <code>xelk-2.2.0-cortexa9hfcortexa9hf_vfp_neon</code> is the name of the channel* <code>http://myyocto.example.com/xelk-2.2.0/cortexa9hf_vfp_neon</code> is the URL of the webserver We assume that network interface has been already configured for Internet access. In any case, a simple network configuration can be done directly on serial console with the following commands: <pre class="board-terminal">root@imx6qxelk:~# ifconfig eth0 192.168.0.94root@imx6qxelk:~# route add default gw 192.168.0.254root@imx6qxelk:~# echo "nameserver 8.8.8.8" > /etc/resolv.conf</pre> For example:'''<pre class="board-terminal">root@imx6qxelk:~# smart channel --add cortexa9hf_neon type=rpm-md baseurl=http://yocto.dave.eu/xelk-3.0.0/cortexa9hf_neon/ Alias: cortexa9hf_neonType: rpm-mdBase URL: http://yocto.dave.eu/xelk-3.0.0/cortexa9hf_neon/ Include this channel? (y/N): y</pre>
You can also add a ''local'' directory, for example mounted via NFS directly on target, with the following command:
After you configure the channel and/or update packages feed on server, you need to update smart database:
