Updated: Nov 23, 2020

Most of the time EMMC flash is not enough. On this blog post, we will explain how to move your root file system on EMMC flash to SSD storage on M.2 slot.

This post applicable to:

  • DSBoard-NX2,

  • DSBOX-NX2,

  • DSBOX-N2.


  1. Connect your M.2 compatible storage device to M.2 connector(For DSBOX-NX2 and DSBOX-N2 you have to open it's casing) of your device while it is powered off.

  2. Connect basic interfaces(HDMI, keyboard, mouse, ethernet) then power on.

To copy the Root File System, you have to find the name of the newly connected storage device. To this, you can use gnome-disks command on terminal.

Format the disk as ext4 format(partition size is up to you but must be min 16GB).

Copy the script which attached below to the device then extract it.

Open a new terminal and run script with new partition name. This script copy file system on EMMC to SSD then create service to use SSD as the default root file system storage. After this script, reboot your device.
