Run SAM-BA with USB connection (equivalent to serial) and erase the beginning of the SPI flash and then write AT91Bootstrap binary:
# sam-ba -p serial -b sama5d2-xplained -a serialflash -c erase::0x3000 -c writeboot:at91bootstrap-sama5d2_xplained.bin
Opening serial port 'ttyACM0'
Connection opened.
