USER’S GUIDE
Appendix A. Programming the SAMA5D3 EDS Board
A.1 INTRODUCTION
The software installed on the board may not be the most recent, so users should check the software version
as described in
Section 4.4 “IP and MAC Addresses” and update it to the latest version available on the
Microchip website.
A.2 NAND FLASH PROGRAMMING
A.2.1 NAND Flash Programming on Linux
Note: The following procedure is tested with the Ubuntu x64 14.04.05 LTS distribution.
1. Open a terminal window and unzip the file to a folder (for example,
/home
).
$ unzip SAMA5D3_EDS _Images_Vxx.xx.xx.zip
$ cd SAMA5D3_EDS_Images/linux
2. Connect the micro-USB (J12) connector of the SAMA5D3 EDS board to the Linux PC.
3. Connect 12V of power to the SAMA5D3 EDS board.
4. Remove the NAND enable (J20) jumper and press the reset button.

The
/dev/ttyACM0
____ is created. Execute the
$ tail –f /var/log/kernel.log
command
to see this.
5. Insert the NAND enable (J20) jumper.
6. If you are using an x86 system, then run the
flash_board
script in the terminal window. If you are
using an x64 system, then run the
flash_board_x64
script.
$ sudo flash_board
(for x86 system)
$ sudo flash_board_x64
(for x64 system)
7. Once “DONE” is displayed, press the reset button to reboot the SAMA5D3 EDS board.
A.2.2 NAND Flash Programming on Windows
Note: This procedure is tested on Win7 x64 and Win10 x64 versions of Windows.
1. Unzip the zip file to a folder (for example,
C:\tmp
).
2. Open Command Prompt and change the
SAMA5D3_EDS_Images\windows
folder (for example,
C:\tmp\SAMA5D3_EDS_Images\windows
).
3. Connect the micro-USB (J12) connector of the SAMA5D3 EDS board to the Windows PC.
4. Connect 12V of power to the SAMA5D3 EDS board.
5. Remove the NAND enable (J20) jumper and press the reset button.
6. When the PC has Internet connection, it will install “Bossa Program Port” automatically. (The port
number may be different on the system.) See Figure A-1 .
