Before performing production tests, various pieces of software
|
|
|
|
|
need to be installed on Ben and PC, and configuration settings may
|
|
|
|
|
have to be adjusted. The following sections describe the installation
|
|
|
|
|
and configuration process.

For a DUT and reference device role, the <B>ben-wpan</B> utilities
|
|
|
|
|
and the test scripts have to be installed on the PC. For flashing the
|
|
|
|

<B>atusb</B> application
|
|
|
|
|
firmware, also <B>dfu-util</B> and the firmware binary are required.
|
|
|
|
|
<P>
|
|
|
|
|
The instructions below assume that a complete development environment
|
2011-05-28 12:53:18 +03:00
|
|
|
is already present on the PC, including <B>SDL</B> and <B>SDL_gfx</B>.
|
|
|
|
|
If any prerequisites are not met,
|
2011-05-27 23:14:15 +03:00
|
|
|
compilation will fail, and you'll have to install the corresponding
|
|
|
|
|
package and try again.

To build the ben-wpan tools and install them under

|
|
|
<SAMP>/usr/local/</SAMP> on the local machine,
|
|
|
|
|
run the following commands:
|
|
|
|
|
<PRE>
|
|
|
|
|
git clone git://projects.qi-hardware.com/ben-wpan.git
|
|

make install
|
|
|

</PRE>
|
|

|
|
<P>
|
|
|
|
|
A different directory prefix can be chosen by overriding the
|
|
|
|
|
<B>INSTALL_PREFIX</B> variable, e.g.,
|
|
|
|
|
<PRE>
|
|
|

make INSTALL_PREFIX=/usr install
|
|
|
|
|
</PRE>

<P>

Note that the test scripts expect <SAMP>${INSTALL_PREFIX}/bin</SAMP>
|
|
|
|
|
to be in <B>PATH</B>.

To simplify accessing the Ben via TCP/IP, its IP address should be
|
|
|
|
|
registered in the hosts file on the PC. If the Ben is running OpenWrt,
|
|
|
|
|
use the following command:
|
|
|
|
|
<PRE>
|
|
|
|
|
echo 192.168.254.101 ben >>/etc/hosts
|
|
|
|
|
</PRE>
|
|
|
|
|
<P>
|
|
|
|
|
If the Ben is running Jlime, the address would be as follows:
|
|
|
|
|
<PRE>
|
|
|
|
|
echo 192.168.1.202 ben >>/etc/hosts
|
|

|
|
</PRE>
|
|
|
|
|
<P>
|
|
|
|
|
If using the same PC with Bens running OpenWrt and Jlime, one may choose
|
|
|
|
|
different host names depending on the distribution, and adapt the commands
|
|
|
|
|
used in the production and testing process accordingly. For example,
|
|
|
|
|
<PRE>
|
|
|
|
|
echo 192.168.254.101 ben >>/etc/hosts
|

To build and install the <B>ben-wpan</B> tools on the Ben, first set
|
|
|
|
|
up networking between the PC and the Ben. If you have not yet checked

Next, if on OpenWrt, compile the tools with
|

make TARGET=ben_openwrt

Once the Ben has booted and started USB networking, the interface
|
|
|
|
|
on the PC side is configured as follows:
|
|
|
|
|
<PRE>
|
|
|
|
|
ifconfig usb0 192.168.254.100 up
|
|
|
|
|
</PRE>
|
|
|
|
|
<P>
|
|
|
|
|
These are the settings for OpenWrt, assuming the network device is
|
|
|
|
|
called "usb0". If using Jlime, the command would be as follows:
|
|
|
|
|
<PRE>
|
|
|
|
|
ifconfig usb0 192.168.1.200 up
|
|
|

|
Before running any of the ben-wpan utilities, other users of the 8:10
|
|
|
|
|
card slot have to be disabled. In a Ben running the regular OpenWrt or
|
|
|
|
|
Jlime distribution, the only such user that is automatically started
|
|
|
|
|
is the MMC kernel driver. The following command disables it:
|
|
|
|
|
<PRE>
|
|
|
|
|
echo jz4740-mmc.0 >/sys/bus/platform/drivers/jz4740-mmc/unbind
|
|
|
|
|
</PRE>
|
|
|
|
|
<P>
|
|
|
|
|
If a WPAN-enabled kernel has been installed, the AT86RF230 driver takes
|
|
|
|
|
the place of the MMC driver. To disable it, run
|
|
|
|
|
<PRE>
|
|
|
|
|
echo spi2.0 >/sys/bus/spi/drivers/at86rf230/unbind
|

Some of the functional tests measure characteristics that are strongly
|
|
|
|
|
influenced by the test setup. It is therefore not possible to provide
|
|
|
|
|
universally applicable reference values, but they have to be measured
|
|
|
|
|
in the actual test environment.

Insert a known to be good <B>atben</B> board and run the following
|
|
|
|
|
command directly on the Ben to record the reference value for the
|
|
|
|
|
clock count with an accuracy of about +/−20 ppm:
|
|
|
|
|
<PRE>
|
|
|
|
|
atrf-xtal 1000 >ben.xtal
|
|
|
|
|
</PRE>
|
|
|
|
|
<P>
|
2011-05-19 22:56:34 +03:00
|
|
|
This takes about 5 seconds.
|
|
|
|
|
<P>
|
|
|
|
|
Note that the result depends on the tolerance of the crystal in the Ben
|
|
|
|
|
and is also affected by temperature. Good accuracy can therefore
|
2011-05-19 22:17:34 +03:00
|
|
|
only be obtained if this measurement is performed individually on each
|
|
|
|
|
Ben, and if a stable temperature is maintained.
