Ettus USRP E100 usage for current osmo-trx

Hello all! Does anybody have any actual information about the possibility to run osmo-trx on Ettus E100 board? I see some references in manuals about the possibility of running it, but I can't find details on how to do it. I tried several ways: 1. Build from source on target HW. Unfortunately "autoreconf" crashes with some perl module dependency. 2. Install binaries. Binaries for arm available only for Debian 9, so I built an image and installed Debian 9.0 on SD-card. Installation of binaries was unsuccessful because of some unmet dependencies. 3. Build from scratch on Debian 9.0. I was partially successful in it. I was able to build osmocore and osmo-trx. The problem was to run it because now, uhd_find_devices shows an empty list. It looks like that kernel module usrp_e.ko should be loaded, but I have no idea where to find its sources. And one more question: Is it a proper place to ask questions related to BTS and TRX? Should I move my question to some other mail list? Thank you Ivan
