In this case, the configuration of J16, S6 and S7 must be changed. Refer to Table 4-1. 2.6 Getting Started The AT91SAM7A3-EK evaluation board is delivered with a DVD-ROM containing all necessary information and step-by-step procedures for working with the most common development tool chains. Please refer to this DVD-ROM, or to the Atmel web site, http://www.atmel.com/products/AT91/, for the most up-to-date information on getting started with the AT91SAM7A3-EK. Note that the AT91SAM7A3 microcontroller fitted on the evaluation board has been programmed with the SAM Boot Assistant (SAM-BA ™ ) which provides an easy way to program the embedded Flash memory through the USB or DBGU communication channel. Programming through DBGU requires that the evaluation kit is powered using a Power Supply USB Adapter Note: The SAM-BA Boot Assistant resides in the embedded Flash memory and will be deleted when programming the Flash. A JTAG/ICE interface is required to recover SAM-BA Boot Assistant.
