=== Introduction ===
The Atmel SAM E54 is a microcontroller based on the Arm Cortex M4 processor architecture. Atmel/Microchip provides the '''SAM E54 Xplained Pro''' development board for getting your feet wet in programming this MCU.
<br />
<br />
There are four variants of the E54 that differ in Flash memory capacity and pin numbers. The Xplained Pro board uses the ATSAME54P20A with 1 MB Flash memory.

===== Setting up Atmel Studio in VirtualBox on Ubuntu =====
These instructions apply when you have installed Atmel Studio in a VirtualBox container with Windows 7 as client OS and Ubuntu being the host OS. 
<br />
====== '''USB Access''' ======
In order for Atmel Studio to recognize the Xplained Pro board when a USB cable is connected to the "Debug USB" port, you need to
* allow the VirtualBox instance access to the USB connection with the Xplained Pro board,
* set up the VirtualBox instance to allow Windows to access the USB port.
<br />
To allow VirtualBox instances that were started from you user account to access USB connections your user needs to be in the ''vboxusers'' group.
<br />
You can check which groups your user is a member of by typing
<pre class="terminal">
id <your login name>
</pre>
<br />
You can add yourself to the ''vboxusers'' group by typing
<pre class="terminal">
sudo usermod -aG vboxusers <your login name>
</pre>
which will become effective only after logging out (or rebooting) and logging in again.
<br />
<br />
To allow the client OS (Windows) to access the USB connections you will need to select the correct USB controller (OHCI vs EHCI vs xHCI) and add a filter for each device that needs to accessed. The filter, which I named "SAME54 XPlained Pro", enables access to all USB device with vendor ID ''03eb'' and product ID ''2111'', which are hexadecimal numbers.
