If you are not already running a TFTP server, follow the next steps to install and configure a TFTP server on your Ubuntu 16.04 host:
$ sudo apt-get install tftpd-hpa
The tftpd-hpa configuration file is installed in /etc/default/tftpd-hpa. By default, it uses /var/lib/tftpboot as the root TFTP folder. Change the folder permissions to make it accessible to all users using the following command:
$ sudo chmod 1777 /var/lib/tftpboot
Now copy the Linux kernel and device tree for the Wandboard Quad Plus from your build directory as follows:
$ cd /opt/yocto/fsl-community-bsp/wandboard/tmp/deploy/images/wandboard/ $ cp zImage-wandboard.bin zImage-imx6qp-wandboard-revd1.dtb /var/lib/tftpboot
If you have a different hardware variant or revision of the Wandboard, you will need to use a different device tree, as shown next. The corresponding device trees for the Wandboard Quad are:
- revision b1: zImage-imx6q-wandboard-revb1.dtb
- revision c1: zImage-imx6q-wandboard.dtb
- revision d1: zImage-imx6q-wandboard-revd1.dtb
- revision b1: zImage-imx6dl-wandboard-revb1.dtb
- revision c1: zImage-imx6dl-wandboard.dtb
- revision d1: zImage-imx6dl-wandboard-revd1.dtb
- revision d1: zImage-imx6qp-wandboard-revd1.dtb
