- 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 ..//tmp/deploy/images//fsl-image-gui-.tar.gz
$ sudo gedit /etc/exports
Add the following line:
/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 the following:
$ 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
}
and run:
$ sudo mkdir /tftpboot $ sudo chmod -R 777 /tftpboot $ sudo /etc/init.d/xinetd restart $ cd // $ cp tmp/deploy/images// /tftpboot $ for f in tmp/deploy/images//*.dtb; do if [[ -L $f ]] && [[ $f != *.dtb ]]; then sudo cp $f /tftpboot; fi done $ 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 $ setenv bootcmd run netboot $ saveenv
You are all set. Connect Ethernet cable, power cycle the and it should boot over NFS.
