Booting from NFS[edit | edit source]
This configuration is very helpful during the software development (both for kernel and applications). The kernel image is downloaded via TFTP while the root file system is remotely mounted via NFS from the host. It is assumed that the development host:
- is connected with the target host board through an Ethernet LAN
- exports the directory containing the root file system for the target through the NFS server
- runs a TFTP server.
- has a proper subnet IP address
net_nfs configuration[edit | edit source]
DESK-MX6-L Virtual Machine is properly configured for the TFTP and NFS debug.
In any case, some variables has to be configured on the target and the VM itself has to be configured for respect to the network environment.
Host (Virtual Machine) configuration[edit | edit source]
The DESK-MX6-L Virtual Machine has the tftp and nfs services already running. Optionally, their configuration has to be changed according to the network configuration where the target is connected to.
Check and properly configure the items the following chapters: network adapter, nfs server
network adapter[edit | edit source]
The network adpater should be configured in bridge mode in order to allow the target to get the files from the VM
then, modify the network interfaces configuration using the netplan configuration file, for example (sse Ubuntu network configuration):
dvdk@vagrant:~$ cat /etc/netplan/01-netcfg.yaml
network:
version: 2
ethernets:
eth0:
dhcp4: false
addresses:
- 192.168.0.125/24
gateway4: 192.168.0.254
nameservers:
addresses: [8.8.8.8, 1.1.1.1]
dvdk@vagrant:~$
and restart it:
dvdk@vagrant:~$ sudo netplan apply dvdk@vagrant:~$
Check or re-configure the Host IP address
dvdk@vagrant:~$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether 08:00:27:b1:28:5d brd ff:ff:ff:ff:ff:ff
inet 192.168.0.125/24 brd 192.168.0.255 scope global eth0
valid_lft forever preferred_lft forever
inet6 fe80::a00:27ff:feb1:285d/64 scope link
valid_lft forever preferred_lft forever
dvdk@vagrant:~$
nfs server[edit | edit source]
The NFS server should exports the correct file system directory (in our example)
dvdk@vagrant:~$ cat /etc/exports /home 0.0.0.0/0.0.0.0(rw,sync,no_root_squash,no_subtree_check,crossmnt) dvdk@vagrant:~$
otherwise, change its configuration and then restart the nfs server:
dvdk@vagrant:~$ sudo /etc/init.d/nfs-kernel-server restart [ ok ] Restarting nfs-kernel-server (via systemctl): nfs-kernel-server.service. dvdk@vagrant:~$
Target configuration[edit | edit source]
The IP address for server and target should be configured: an example (for a network subnet 192.168.0.x)
=> setenv serverip 192.168.0.125 => setenv ipaddr 192.168.0.90
serveripis the IP address of the host machine running the tftp/nfs serveripaddris the IP address of the target
The kernel and device tree files has to be selected
=> setenv bootfile desk-mx-l/desk-mx6-l-3.0.0_uImage => setenv fdtfile desk-mx-l/desk-mx6-l-3.0.0_imx6dl-sbcx-cb0012.dtb
finally, the root file system directory on the Virtual Machine should be configured for let the kernel to find the INIT
=> setenv rootpath /home/dvdk/desk-mx-l/rfs/desk-mx6-l
To run this configuration just issue the net_nfs command which firstly download the kernel and device tree using the tftp protocol
=> run net_nfs
