<H1>Production and testing: Software setup</H1>
|
|
|
|
Before performing any production tests, various pieces of software
|
|
need to be installed on Ben and PC, and configuration settings
|
|

<H3>Register Ben host name</H3>
|
|
|
|
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
|
|
echo 192.168.1.202 jlime >>/etc/hosts
|
|
</PRE>
|
|
|
|

|
<H2>Ben system setup</H2>
|
|
|
|
The configuration setting described in this section are lost on each
|
|
reset or reboot and either need to be entered again. Alternatively,
|
|
a setup script running at boot time can be written.
|
|
|
|
|
|
<!-- ---------------------------------------------------------------------- -->
|
|
|
|
|
|
<H3>Enable network access</H3>
|
|
|
|
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
|
|
</PRE>
|
|
|
|
|
|
<!-- ---------------------------------------------------------------------- -->
|
|
|
|
|
|
<H3>Silence other 8:10 card users</H3>
|
|
|
|
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
|
|
</PRE>
|
|
|
|
|
|
<!-- ---------------------------------------------------------------------- -->
|
|
|
|
|
|
<H3>Start atrf-proxy</H3>
|
|
|
|
On the Ben, launch the proxy daemon. We pass the option -b to background it:
|
|
<PRE>
|
|
atrf-proxy -b
|
|
</PRE>
|
|
|

|
|
|
<H3>Password-less remote access</H3>
|
|
|
|
To enable password-less remote access from the PC, set up network
|
|
access to the Ben and run the following command:
|
|
<PRE>
|
|
ssh ben 'cat >>/etc/dropbear/authorized_keys' <~/.ssh/id_rsa.pub
|
|
</PRE>
|
|

<H2>Test profiles</H2>
|
|
|
|
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.
|
|
|
|
|
|
<!-- ---------------------------------------------------------------------- -->
|
|
|
|
|
|
<H3>Clock count (atben only)</H3>
|
|
|
|
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>
|
|
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
|
|
only be obtained if this measurement is performed individually on each
|
|
Ben, and if a stable temperature is maintained.
