We use the Buildroot as the root file system.

How to Build the Buildroot:

Install the cross compiler and the toolchain required on your Linux Ubuntu PC following this article (Tested on Ubuntu 12.04):

Copy the rootfs.tar.bz2 to the PC /tmp folder, then do the follow command to uncompress it:

~$ cd ~
~$ sudo tar xvf /tmp/rootfs.tar.bz2 -C .

This is a fork of the original Atmel version available on GitHub.

Do the filesystem with the follow command:

~$ sudo mkubifsimage rootfs/ ubifs.img

Then we will get the ubifs.img file, you can copy it to the USB Disk/Micro TF card for update the board system image.

The atmel provide the method to Build the Buildroot filesystem, if you want to do it by yourself, refer the atmel linux4sam website.

A compiled version of Root file system is available on:
