- Yocto Setup TFTP/NFS
Running Yocto rootfs on Variscite board using TFTP & NFS
Host
Make sure you installed NFS server:
$ sudo apt-get install nfs-kernel-server $ cd $ sudo mkdir rootfs $ cd rootfs $ sudo tar xvf ../build_x11/tmp/deploy/images//fsl-image-qt5-.tar.bz2
$ sudo gedit /etc/exports
add the following line (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 $ cd // $ cp tmp/deploy/images// /tftpboot $ cp tmp/deploy/images/-imx*.dtb /tftpboot $ sudo rename 's/-//' /tftpboot/-*.dtb
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 /rootfs (change <uname> to the name of user) $ setenv bootcmd run netboot $ saveenv
You are all set. Pushing reset on the board will run your Yocto result file system.
