DART-6UL - 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 ~/var-fslc-yocto
$ sudo mkdir rootfs
$ cd rootfs
$ sudo tar xvf  ../build_x11/tmp/deploy/images/imx6ul-var-dart/fsl-image-gui-imx6ul-var-dart.tar.gz
$ sudo gedit /etc/exports

Add the following line (change <uname> to the name of user):

/home/<uname>/var-fslc-yocto/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 ~/var-fslc-yocto/build_x11/


$ sudo cp tmp/deploy/images/imx6ul-var-dart/zImage /tftpboot
$ for f in tmp/deploy/images/imx6ul-var-dart/*.dtb; do if [[ -L $f ]] && [[ $f != *imx6ul-var-dart.dtb ]]; then sudo cp $f /tftpboot; fi done
$ sudo rename 's/zImage-//' /tftpboot/zImage-*.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 /home/<uname>/var-fslc-yocto/rootfs (change <uname> to the name of user)
=> setenv bootcmd run netboot
=> saveenv 

You are all set. Connect Ethernet cable, power cycle the DART-6UL and it should boot over NFS.
