<p>I have now built osmo-trx-lms and osmo-bts-trx from source on an
i386 platform.</p>
<p>I have beacon, and two phones registered, the configuration from
msc and up is the one</p>
<p>I had three weeks ago, which more or less worked, but with large
stability problems.</p>
<p>I guess *this* report is the most interesting for you now....</p>
<p>I build from the "master", and target debian9 on i386.<br>
</p>
<p><br>
</p>
<p>I have not been able to make a call yet, possibly because I might
have messed up some</p>
<p>library the MSC is dependent on, but I will work on that.</p>
<p>What is interesting is that bts 0 trx 0 is running trx-uhd with a
B100, and seems quite stable.</p>
<p>Moreover, bts 1 trx 0 is running on the i386 and seems happy so
far, after 30 minutes.</p>
<p>This is Limesdr mini.<br>
</p>
<p><br>
</p>
<p>I have just copied the bts0 to trx 0 section from my original
config, duplicated it and changed <br>
</p>
<p>bts0 to bts1, and the ipa unit-id 1805 0, and of course the ip
addresses. <br>
</p>
<p>I will comment the various lines in my configs, as I have
understood them, and look forward to your</p>
<p>comments, or maybe a keyword list explaining what each parameter
is used for.</p>
