SMART ARM-based Microcontrollers
AT15004:Using SAM-BA for Linux on SAM
Devices
APPLICATION NOTE
Introduction
A few of the SAM devices are pre-loaded with the Atmel® SAM Boot
Assistant (Atmel SAM-BA®). This bootloader allows In-System Programming
(ISP) from USB host without using any other external programming interface.
SAM-BA has been validated on various Linux distributions such as Ubuntu,
Debian, Fedora, openSUSE, and Mint. However, it will work on other
distributions as well. Tested distributions are listed at www.at91.com/
linux4sam.
This application note describes the steps to install and use SAM-BA on
some popular Linux distributions to program Atmel ARM® based devices.
Features
•Allows to program, verify, and secure an Atmel SAM device without
using a device programmer
•Uses USB CDC class for communicating to the host
•Use SAM-BA Command Line mode to program SAM devices
•Source code for SAM-BA applet is available and can be customized to
user’s needs such as Encrypted loader and custom protocol

1. Introduction to SAM-BA
The SAM-BA GUI tool provides a means to easily program various Atmel ARM ® processor based
microcontrollers.
The key features of SAM-BA GUI are:
•performs In-System Programming through JTAG, RS232, or USB interfaces
•on-chip and on-board memories programming solutions
•can be used via a Graphical User Interface or started in batch mode from a command line
•memories and peripheral register display content
•user scripts executable from SAM-BA GUI or a shell
•operates on both Windows or Linux OS
Note:
1. SAM-BA for Linux supports only the USB interface.
2. Linux Mint 17.2 LTS and Fedora 23 will be used as the Linux distribution reference for the
application note.
