Extending SAM-BA Programming Capabilities 1. Scope AT91 ARM ™ The SAM Boot Assistant (SAM-BA ) software provides a means of easily program- ® ® ® Thumb ming different Atmel AT91SAM ARM Thumb -based devices. It runs under Windows®2000 and XP. Microcontrollers Communicating with the target device may be done through an RS232, USB or JTAG link. SAM-BA now uses AT91Boot_DLL.dll to communicate with the target. Application Note This document describes how to extend SAM-BA capabilities to program any kind of memory. The example provided with this document describes how to program a large NAND Flash memory block. 1.1 Reference Documents The following table gives the references of the documents and their denominations in this document.
