.P
.SH SYNOPSIS
.P
\fBfwflash\fR \fIfile\fR
.P
.SH DESCRIPTION
.P
The \fBfwflash\fR 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.\&
.P
Connect the NXT using a USB cable.\& Make sure it is detected by the computer
when powered on.\& If you run \fBfwflash\fR now, it should report that the NXT is
found, but not running in reset mode.\&
.P
\fBThe next step will erase the current firmware image!\&\fR
.P
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.\&
.P
You can then use \fBfwflash\fR to send the firmware.\& After a few seconds, it
should announce successful flashing.\&
.P
In case of problem, check your USB cable, and your device permissions.\&
