Guide on how to Setup NFS client on STM32MP2X

[niuwenxu]

 

This guide uses ubuntu22.04 x86 pc(Probably the same on any other Linux system) as host, and mp2 as device.

Its quite a common practice to use NFS as a medium to transfer cross compiled binary to dev board, since using sftp or scp to transfer the file every time you cross compile is tedious and time consuming.

 

• Install NFS server and prepare the export directory on host : 

         sudo apt update && sudo apt install nfs-kernel-server 

         sudo mkdir -p /host_export_srv_dir 

         sudo chown -R nobody:nogroup /host_export_srv_dir

         sudo chmod 777 /home/srv 

 

• Edit export file on host: 

         sudo vim /etc/exports 

             /home/srv  *(rw,sync,no_subtree_check) 

 

• Export the directory

           sudo exportfs -a 

           sudo systemctl restart nfs-kernel-server 

 

• Disable the firewall on host

            sudo ufw allow from MP2IPAddr to any port nfs 

             sudo ufw enable 

             sudo ufw status 

 

• Install the nfs client on device: 

              Please run as su

              apt update && apt install  nfs-utils 

 

• Mount the NFS directory on device

             mount -v -t nfs  138.198.198.58:/home/srv /srv 

 

• To Mount NFS on boot, Edit /etc/fstab  file on device to : 

            Warning: it may make boot time longer 

             138.198.198.58:/home/srv     /srv         nfs        defaults              0  0 

 

 

 

 

• Extra note:

           Please use df command to check mount successfully or not.

 

        

 

         To un-mount volume on device: 

          umount /srv
