Dear USRP Community, I am working on OAI project, and trying to run enb using USRP n310. My uhd version was 3.15 LTS. But as part of the installation for OAI, I used this command in a different workstation:
*git clone git://github.com/EttusResearch/uhd.git <http://github.com/EttusResearch/uhd.git> cd uhd; mkdir host/build; cd host/build cmake -DCMAKE_INSTALL_PREFIX=/usr .. make -j4 sudo make install sudo ldconfigsudo /usr/lib/uhd/utils/uhd_images_downloader.py* But, now I am getting an error in the enb trace as follows: ***************************----trace---***************** --- ----- ------ wait_eNBs() Waiting for eNB L1 instances to all get configured ... sleeping 50ms (nb_L1_inst 1) RC.nb_L1_CC[0]:1 eNB L1 are configured About to Init RU threads RC.nb_RU:1 Initializing RU threads [PHY] DJP - delete code above this /home/ubuntu18/openairinterface5g/targets/RT/USER/lte-ru.c:2704 [PHY] Copying frame parms from eNB 0 to ru 0 [PHY] Initializing RRU descriptor 0 : (local RF,synch_to_ext_device,0) [PHY] NFGI_RRU_IF4p5: configuring ru_id 0 (start_rf 0x56469465fc30) [PHY] channel 0, Setting tx_gain offset 0.000000, rx_gain offset 110.000000, tx_freq 2630000000.000000, rx_freq 2510000000.000000 [PHY] Initializing frame parms for N_RB_DL 50, Ncp 0, osf 1 [PHY] lte_parms.c: Setting N_RB_DL to 50, ofdm_symbol_size 1024 [PHY] Starting ru_thread 0, is_slave 0, send_dmrs 0 [PHY] Initializing RU proc 0 (eNodeB_3GPP,synch_to_ext_device), [PHY] init_RU_proc() DJP - added creation of pthread_prach [HW] thread_top_init() called with affinity>0, but overruled by #ifndef CPU_AFFINITY.
