Closing JP3 and powering the board will assert ERASE and clear GPNVM bit 1, and thereby selects the boot from the ROM by default. The MCU will boot from the internal ROM to enable a SAM-BA connection through the UART. Connect the SAM4S-EK UART port (J3) to a PC COM port through an RS232 cross- over cable. -
