Hi,

I have an Odroid-XU I have setup with Debian Wheezy and a USRP B200. After building the UHD drivers from source, I followed the "network from scratch" page. I also configured and built osmo-trx with the --with-neon-vfpv4 option. Things are running OK, a whole lot better than my attempt with OpenBTS actually. I"m able to connect to the network with my Samsung S4 phone, but after an hour or so of the BTS running, I get a UHD recieved time out error (see below). I wonder what could be causing this? I have the B200 plugged into the USB 3.0 port, along with external power.

Thanks in advance for any help.
