<P>
The microcontroller of <B>atusb</B> contains firmware that must be
loaded before the testing process can commence. The firmware consists
of the following two parts:
<OL>
<LI>The boot loader (via serial programming, using <B>avrdude</B>)
<LI>The application (via DFU, using <B>dfu-util</B>)
</OL>
<P>
Note that <B>atben</B> has no microcontroller and therefore does not need
any flashing.
<!-- ====================================================================== -->
<SECTION ref="boot" title="Flashing the boot loader">
The following image shows the setup for flashing the boot loader:
<P>
<IMG src="setup-C.png">
<P>
To flash the boot loader,
<UL>
<LI>insert the <B>atusb-pgm</B> board into the Ben
<LI>place the <B>atusb</B> board (DUT) on the table near the Ben,
without connecting it to USB
<LI>place <B>atusb-pgm</B> on <B>atusb</B> as shown in the image below
and gently push it on the contacts
<P>
<A href="atusb-programming.jpg"><IMG

<P>
<LI>finally, run
<PRE>
make flash
</PRE>
</UL>
<P>
The flashing takes about 20-30 seconds. If it should fail, make sure you
properly placed <B>atusb-pgm</B> and try again. If it keeps on failing,
remove <B>atusb-pgm</B> from the Ben and insert it again.
If flashing fails despite numerous attempts, proceed to the
<A href="analysis.html">fault analysis</A>.
<!-- ====================================================================== -->
<SECTION ref="app" title="Flashing the application">
The flashing script proceeds automatically to the flashing of the
application. All you need to do is insert the <B>atusb</B> board
into the PC:
<P>
<IMG src="setup-D.png">
<P>
The flashing script will wait up to 30 seconds for enumeration.
Once the <B>atusb</B> board has been detected, the script transfers
the application with DFU. After this, you can proceed with the
<A href="test.html">functional test</A>.
<P>
If the board fails to enumerate, proceed with the
<A href="analysis.html">fault analysis</A>.
