Setup TFTP/NFS Yocto system
Running Yocto rootfs on Variscite board using TFTP & NFS
Host
Make sure you installed NFS server:
$ sudo apt-get install nfs-kernel-server $ cd ~ $ mkdir rootfs $ cd rootfs $ sudo tar xvf ~/var-imx-yocto-krogoth/build_x11/tmp/deploy/images/var-som-mx6/fsl-image-gui-var-som-mx6.tar.bz2
$ sudo gedit /etc/exports
add (change <uname> to the name of user):
/home/<uname>/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
$ sudo cp ~/var-imx-yocto-krogoth/build_x11/tmp/deploy/images/var-som-mx6/uImage /tftpboot $ sudo cp ~/var-imx-yocto-krogoth/build_x11/tmp/deploy/images/var-som-mx6/uImage-imx*.dtb /tftpboot/ $ sudo rename 's/uImage-//' /tftpboot/uImage-*
Target
Make sure you have a serial connection to the target.
Reset and hold the space bar. This will bring you to U-Boot command line.
$ setenv serverip 192.168.1.188 $ setenv nfsroot /home/<uname>/rootfs (change <uname> to the name of user) $ setenv bootcmd run netboot $ saveenv
You are all set. Pushing reset on the VAR-SOM-MX6 board will run your Yocto result file system.
