BOSSA is a flash programming utility for Atmel's SAM family of flash-based ARM microcontrollers. The motivation behind BOSSA is to create a simple, easy-to-use, open source utility to replace Atmel's SAM-BA software. BOSSA is an acronym for Basic Open Source SAM-BA Application to reflect that goal.

The software was created by Scott Shumate with contributions from several contributors.

* Device families which are not tested for each release and could stop working.

Do you want to help make sure a device family is tested or do you want to see a new device family added? Then contribute a development board with a device from that family to the BOSSA project to make it happen. Contact scott at shumatech.com if you are interested in helping the project.

The following individuals and companies graciously provided development boards to assist the BOSSA project.

• Atmel Corporation (SAM3N, SAM3S, SAM3U)
• David Crocker (SAM4E, SAM4S)
• Adafruit Industries (SAMD21, SAMD51)
