Most of the time EMMC flash is not enough. In this blog post, we will explain how to move your root file system on EMMC flash to SDCard on SDMMC slot. This process can be used for all JetPack versions.

This post applicable to:

  • DSBOX-NX2,
  • DSBOX-N2.


  1. Connect SDCard to your device while it is powered off.
  2. Connect basic interfaces(HDMI, keyboard, mouse, ethernet) then power on.

To copy Root File System, you have to find the name of the newly connected storage device. To do this, you can use gnome-disks command on terminal.Its name must be /dev/mmcblk1 but double check it.

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