SAM-BA Boot Assistant

The SAM-BA™ Boot Recovery restores the SAM-BA Boot in the first two sectors of the on-chip

Flash memory. The SAM-BA Boot recovery is performed when the TST pin and the PA0, PA1

and PA2 pins are all tied high.

The SAM-BA Boot Assistant is a default Boot Program that provides an easy way to program in

situ the on-chip Flash memory.

The SAM-BA Boot Assistant supports serial communication through the DBGU or through the

USB Device Port. (The AT91SAM7S32 has no USB Device Port.)

• Communication through the DBGU supports a wide range of crystals from 3 to 20 MHz via

software auto-detection.

• Communication through the USB Device Port is limited to an 18.432 MHz crystal. (

The SAM-BA Boot provides an interface with SAM-BA Graphic User Interface (GUI).
