Atmel ATSAM3U-EK Data Sheet

6478E–ATARM–30-Mar-11

Unpack the board taking care to avoid electrostatic discharge. Unpack the power supply, select the right 
power plug adapter corresponding to that of your country, and insert it in the power supply.

Connect the power supply DC connector to the board and plug the power supply to an AC power plug.

The board LCD should light up and display a welcome page. Then, click or touch icons displayed on the 
screen and enjoy the demo.

The SAM3U-EK ships with a 3V coin battery. 

This battery is not required for the board to start up. 

The coin battery is provided for user convenience in case the user would like to exercise the date and 
time backup function of the SAM3U series devices when the board is switched off. 

The on-board NAND Flash contains “SAM3U-EK DevStart”. 

It is stored in the “SAM3U-EK DevStart” folder on the USB Flash disk available when the SAM3U-EK is 
connected to a host computer and you click on the Flash Disk icon of the on-board demo. 

Click the file “welcome.html” in this folder to launch SAM3U-EK DevStart.

SAM3U-EK DevStart guides you through installation processes of IAR

™

 EWARM, Keil MDK and GNU 

toolkits. Then, it gives you step-by-step instructions on how to rebuild a single example project and how 
to program it into the SAM3U-EK. Optionally, if you have a SAM-ICE

™

, instructions are also given about 

how to debug the code.

The DevStart ends by giving step-by-step instructions on how to recover the SAM3U-EK to the state as it 
was when shipped by Atmel. 

Follow the instructions if you deleted the contents of the embedded Flash or the NAND Flash and want 
to recover from this situation.
