Host
Make sure you installed NFS server:
$ sudo apt-get install nfs-kernel-server $ cd ~/var-som-mx6-yocto-fido $ sudo mkdir rootfs $ cd rootfs $ sudo tar xvf ../build_x11/tmp/deploy/images/var-som-mx6/fsl-image-qt5-var-som-mx6.tar.bz2
$ sudo gedit /etc/exports
add:
/home/<uname>/var-som-mx6-yocto-fido/rootfs *(rw,sync,no_root_squash,no_all_squash,no_subtree_check)
exit & save
$ sudo /etc/init.d/nfs-kernel-server restart
Make sure you installed TFTP server:
$ sudo apt-get install xinetd tftpd tftp Verify: $ ls /usr/sbin/in.tftpd $ sudo gedit /etc/xinetd.d/tftp service tftp { protocol = udp port = 69 socket_type = dgram wait = yes user = nobody server = /usr/sbin/in.tftpd server_args = /tftpboot disable = no } $ sudo mkdir /tftpboot $ sudo chmod -R 777 /tftpboot $ sudo /etc/init.d/xinetd restart $ cd ~/var-som-mx6-yocto-fido/build_x11/ $ cp tmp/deploy/images/var-som-mx6/uImage /tftpboot $ cp tmp/deploy/images/var-som-mx6/uImage-imx6dl-var-som.dtb /tftpboot/imx6dl-var-som.dtb $ cp tmp/deploy/images/var-som-mx6/uImage-imx6dl-var-som-solo.dtb /tftpboot/imx6dl-var-som-solo.dtb $ cp tmp/deploy/images/var-som-mx6/uImage-imx6dl-var-som-solo-vsc.dtb /tftpboot/imx6dl-var-som-solo-vsc.dtb $ cp tmp/deploy/images/var-som-mx6/uImage-imx6q-var-dart.dtb /tftpboot/var-dart.dtb $ cp tmp/deploy/images/var-som-mx6/uImage-imx6q-var-som.dtb /tftpboot/imx6q-var-som.dtb $ cp tmp/deploy/images/var-som-mx6/uImage-imx6q-var-som-vsc.dtb /tftpboot/imx6q-var-som-vsc.dtb

make sure you have a serial connection to the target.
reset and hold the space bar. This will bring you to U-Boot prompt
$ setenv serverip 192.168.1.188 $ setenv kernel uImage $ setenv console ttymxc0 $ setenv nfsroot /home/<uname>/var-som-mx6-yocto-fido/rootfs $ setenv bootcmd run netboot $ saveenv
You are all set. Pushing reset on the VAR-SOM-MX6 board will run your Yocto result file system.
