Hi Ben,
Your latest release fixed my previous issue during build. thanks. I am currently logged into the LTE eNodeB via telnet, but lte_enodeb is seg faulting when i hit 'start'.
I'm using a USRP1 with an RFX2450 daughter board so band 7 should be within the valid freq range of the daughter board (2300MHz-2900MHz).
The error LTE_fdd_eNodeB returns is:
linux; GNU C++ version 4.6.3; Boost_104800; UHD_003.005.003-163-gfeabc1c7
LTE FDD ENB

What do you suggest here?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Sorry for the delayed response. The current version of the openLTE eNodeB
application only supports B200/B210. For use with your USRP1/RFX2400
setup, you can try adjusting the way the clocking is setup in
LTE_fdd_enb_radio.cc.
