Hello everyone,
     I used B210 to port the srsUE latest version to ower own eNB, but it
shows the following problem, my CPU is 4 cores. Sometimes , it dosen't
decode MIB even.

nick at nick-Aspire-V5-471PG:~/srsUE/build/ue/src$ sudo taskset -c 2-3 ./ue
ue.conf
linux; GNU C++ version 4.8.4; Boost_105400; UHD_3.11.0.git-28-gc66cb1ba
