You'll need to use either a JTAG or the SAM-BA tool.

thanks,

Thanks for your reply
I tried to use SAM-BA
but after i select the "COM3" (which is my linuxstamp)
the SAM-BA windows disappear, and no matter how long i wait, it
doesn't show the main GUI
until i unplug my linuxstamp, it come out with cannot connect message

how to use sam-ba with linuxstamp ?

thanks,
victor

I just use a JTAG, but others have put this together:
