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>
|
2011-05-29 16:04:13 +03:00
|
|
|
<LI>The boot loader (via serial programming, using avrdude)
|
|
|
|
|
<LI>The application (via DFU, using dfu-util)
|

Note that <B>atben</B> has no microcontroller and therefore does not need

2011-05-18 20:43:45 +03:00
|

any flashing.

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

To flash the boot loader,
|
|
|
|

<UL>
|
|
|

<LI>insert the <B>atusb-pgm</B> board into the Ben

|
|
|
|
|
without connecting it to USB
|
2011-05-26 22:13:03 +03:00
|
|
|
<LI>place <B>atusb-pgm</B> on <B>atusb</B> as shown in the image below
|
2011-05-21 18:11:15 +03:00

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>.

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>

2011-05-21 18:11:15 +03:00
|
|
|
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>.
