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-MX8M-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-MX8M-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.
 The Virtual Machine is created following the procedure at the DVDK Virtual Machine wiki page |
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 check or re-configure the Host IP address
dvdk@vagrant:~$ ifconfig

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,async,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 [sudo] password for dvdk: * Stopping NFS kernel daemon [ OK ] * Unexporting directories for NFS kernel daemon... [ OK ] * Exporting directories for NFS kernel daemon... [ OK ] * Starting NFS kernel daemon [ OK ] dvdk@vagrant:~$
Installing the root file system[edit | edit source]
Using the DESK-MX6-L Virtual Machine it is required to extracting the rfs in the exported file system:
- download the
fsl-imx-wayland-glibc-x86_64-meta-toolchain-aarch64-desk-mx8mp-toolchain-5.4-zeus.shfrom the mirror server
dvdk@vagrant:~/desk-mx-l/rfs$ wget https://mirror.dave.eu/desk-mx-l/desk-mx8m-l-2.0.0/dave-image-devel-desk-mx8mp.tar.bz2 dvdk@vagrant:~/desk-mx-l/rfs$
extracting the archive (with root permissions!!) and create the symbolic link:
mkdir /home/dvdk/desk-mx-l/rfs/desk-mx8m-l-2.0.0 sudo tar jxpf dave-image-devel-desk-mx8mp.tar.bz2 -C /home/dvdk/desk-mx-l/rfs/desk-mx8m-l-2.0.0/ ln -s /home/dvdk/desk-mx-l/rfs/desk-mx8m-l-2.0.0 /home/dvdk/desk-mx-l/rfs/desk-mx8m-l
Then, the rfs directory appears like this:
dvdk@vagrant:~/desk-mx-l/rfs$ ls -la total 725876 drwxr-xr-x 4 dvdk dvdk 4096 Feb 15 12:37 . drwxr-xr-x 7 dvdk dvdk 4096 Feb 15 11:50 .. lrwxrwxrwx 1 root root 41 Apr 9 2021 desk-mx6-l -> /home/dvdk/desk-mx-l/rfs/desk-mx6-l-1.0.0 drwxr-xr-x 19 541 502 4096 Jan 25 2021 desk-mx6-l-1.0.0 lrwxrwxrwx 1 dvdk dvdk 46 Feb 15 12:37 desk-mx8m-l -> /home/dvdk/desk-mx-l/rfs/desk-mx8m-l-2.0.0 drwxrwxr-x 8 dvdk dvdk 4096 Feb 15 12:36 desk-mx8m-l-2.0.0 dvdk@vagrant:~/desk-mx-l/rfs$
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 192.168.0.120 => setenv ipaddr 192.168.0.121
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 have to be selected
=> setenv bootfile /tftpboot/desk-mx-l/Image
=> setenv loadk 'tftpboot ${loadaddr} ${serverip}:${bootfile}'
=> setenv loadfdt 'tftpboot ${fdt_addr} ${serverip}:${fdt_file}'
ORCA has its dtb file imx8mp-mito8mplus-cb1001.dtb
setenv fdt_file /tftpboot/desk-mx-l/imx8mp-mito8mplus-cb1001.dtb
while MITO 8M Mini has its own dtb file imx8mm-mito8mmini.dtb
setenv fdt_file /tftpboot/desk-mx-l/imx8mm-mito8mmini.dtb
finally, the root file system directory on the Virtual Machine should be configured to let the kernel find the INIT
=> setenv rootpath /home/dvdk/desk-mx-l/rfs/desk-mx8m-l
To run this configuration just issue the netboot command which firstly downloads the kernel and device tree using the tftp protocol
=> run loadk loadfdt nfsargs addip addcons addmisc; booti ${loadaddr} - ${fdt_addr}
