NAME

       fwflash - flash firmware image to a connected NXT device

SYNOPSIS

       fwflash file

DESCRIPTION

       The  fwflash  utility  takes a firmware image file and sends it to a connected NXT device through USB. It
       takes only one parameter which is the firmware file to send. This file  usually  has  the  .bin  or  .rfw
       extension and a size of 262144 octets.

       Connect  the  NXT using a USB cable. Make sure it is detected by the computer when powered on. If you run
       fwflash now, it should report that the NXT is found, but not running in reset mode.

       The next step will erase the current firmware image!

       Press and hold, for at least five seconds, the reset button which is hidden in the pin hole under the USB
       port. The brick should make a clicking noise and be detected by the computer in SAM-BA mode.

       You can then use fwflash to send the firmware.  After  a  few  seconds,  it  should  announce  successful
       flashing.

       In case of problem, check your USB cable, and your device permissions.

       The fwflash utility is part of LibNXT.
