27The microcontroller of <B>atusb</B> contains firmware that must be
28loaded before the testing process can commence. The firmware consists
29of the following two parts:
30<OL>
31  <LI>The boot loader (via serial programming, using avrdude)
32  <LI>The application (via DFU, using dfu-util)
33</OL>
34<P>
35Note that <B>atben</B> has no microcontroller and therefore does not need
36any flashing.

44The following image shows the setup for flashing the boot loader:

48To flash the boot loader,
49<UL>
50  <LI>insert the <B>atusb-pgm</B> board into the Ben
51  <LI>place the <B>atusb</B> board (DUT) on the table near the Ben,
52    without connecting it to USB
53  <LI>place <B>atusb-pgm</B> on <B>atusb</B> as shown in the image below
54    and gently push it on the contacts
55    <P>

59  <LI>finally, <SAMP>cd</SAMP> to <SAMP>ben-wpan/prod/</SAMP> and run
60    <PRE>
61    make flash

63</UL>
64<P>
65The flashing takes about 20-30 seconds. If it should fail, make sure you
66properly placed <B>atusb-pgm</B> and try again. If it keeps on failing,
67remove <B>atusb-pgm</B> from the Ben and insert it again.
68If flashing fails despite numerous attempts, proceed to the
69<A href="analysis.html">fault analysis</A>.

77The flashing script proceeds automatically to the flashing of the
78application. All you need to do is insert the <B>atusb</B> board
79into the PC:

83The flashing script will wait up to 30 seconds for enumeration.
84Once the <B>atusb</B> board has been detected, the script transfers
85the application with DFU. After this, you can proceed with the
86<A href="test.html">functional test</A>.
87<P>
88If the board fails to enumerate, proceed with the
89<A href="analysis.html">fault analysis</A>.
