Warning: This page is designed to be used with a 'release' URL parameter.
This page is using the default release RELEASE_MORTY_V1.0_DART-6UL.
To view this page for a specific Variscite SoM and software release, please follow these steps:

DART-6UL - Yocto Setup TFTP/NFS
Running Yocto rootfs on Variscite board using TFTP & NFS
On the Host
Prepare the rootfs folder:
$ 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
Make sure the NFS server is installed:
$ sudo apt-get install nfs-kernel-server
Edit /etc/exports. E.g.
$ sudo gedit /etc/exports
...and add the following line to it (replace <uname> with the actual username):
/home/<uname>/var-fslc-yocto/rootfs *(rw,sync,no_root_squash,no_all_squash,no_subtree_check)
Restart the NFS server:
$ sudo /etc/init.d/nfs-kernel-server restart
Make sure the TFTP server is installed:
$ 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
Make adjustments to the rootfs:
When using NetworkManager on the target, configure NetworkManager not to manage the interface used for the NFS boot by adding the following to /home/<uname>/var-fslc-yocto/rootfs/etc/NetworkManager/NetworkManager.conf:
[keyfile] unmanaged-devices=interface-name:eth0
Enable DNS:
$ sudo ln -fs /proc/net/pnp /home/<uname>/var-fslc-yocto/rootfs/etc/resolv.conf
On the Target
Make sure you have a serial connection to the target.
Boot the board and hit any key to stop the autoboot and get to the U-Boot command line. Run the following in the U-Boot command line:
=> setenv serverip <HOST_IP_ADDRESS> (replace <HOST_IP_ADDRESS> with the actual IP address of your host - run 'ifconfig' on the host to get it) => setenv nfsroot /home/<uname>/var-fslc-yocto/rootfs (replace <uname> with the actual username) => setenv bootcmd run netboot => saveenv
You are all set. Connect the target board to the same network as the host using an Ethernet cable, power cycle it and it should boot over NFS.
