Using the SAM Boot Assistant (SAM-BA) The PC side of the SAM Boot Assistant, and its User Manual, can be downloaded from Atmel's web site. To have the AT91SAM7S microcontroller on the SAM7-H256 header board copy the MCU side of SAM-BA into its Flash memory, power down the board and close the TST jumper. Power up the board and wait for 10 seconds, then power down the board and remove the jumper. Now you can begin using the SAM-BA GUI for the SAM Boot Assistant with the SAM7-H256 board plugged into your PC's USB port. AT91SAM7S256 Header Board Resources These documents refer to the SAM7-H64 board, which has an AT91SAM7S64 MCU. The form and function is the same; the AT91SAM7S64 only has less memory.
