1. Introduction to SAM-BA

The SAM-BA GUI tool provides a means of easily programming various Atmel ARM processor-based microcontrollers. SAM-BA GUI Key Features:

? Performs in-system programming through JTAG, RS232 or USB interfaces ? On-device and on-board memories programming solutions

? May be used via a Graphical User Interface or started in batch mode from a command line ? Memories and peripherals display content ? User scripts executable from SAM-BA GUI or a shell ? Runs under Windows? or Linux OS

SAM-BA for Linux supports only the USB interface. SAM-BA and its patches are available from Atmel web site at the following address: . SAM-BA has been validated on different Linux distributions such as Ubuntu, Debian?, Fedora?, openSUSE? but it will certainly work on other distributions as well. Tested distributions are referenced on Linux4SAM web site, which is the main starting point for Linux OS on the Atmel ARM-based MPUs, at the following link: . Ubuntu 12.04 LTS will be used as the Linux distribution reference for the next assignments.

2. Setup

With Ubuntu distributions, a user has to be member of the dialout group to access serial devices like RS232 serial port, USB serial, serial modem, etc. As SAM-BA uses the USB serial class driver to connect to the SAMA5D3 Xplained board, it is important to enable serial devices access to the Ubuntu user.

Enable access to serial devices.

? Add current "user" to dialout group:

# cd ~ # sudo adduser at91sam dialout # cat /etc/group | grep dialout dialout:x:20:at91sam

? Log out from Ubuntu and log in again to make the changes effective and access the serial port

Logging out from Ubuntu is mandatory to have the user added to the dialout group. Current user has now access to serial devices including the USB serial port.
