The error message is :

[INFO] [B200] Initialize Radio control... [INFO] [B200] Performing register loopback test... [INFO] [B200] Register loopback test passed [INFO] [B200] Performing register loopback test...

It seems the application crashed just after initialized USRP B210. I want to give you some logs , but the free5GRAN writes logs in /var/log/free5GRAN/free5GRAN.log is empty file, no content at all.

Hello, can you share the config file used ?

gmg2719 commented 3 years ago

Hi, please review cfg file, the file works fine on your formal code, but doesn't work on this code release.

gmg2719 commented 3 years ago

// Scan band for finding cells function: "BAND_SCAN";

// Reception gain (integer) gain: 80;

// Bands list bands: (41,78);

// SSB period in sec. (optional, default is 0.02) ssb_period: 0.02;

// Logging level. (Trace recommended in current version) logging: "trace";

Could you try with only n78 band ?

gmg2719 commented 3 years ago

In fact, I already tried what you said, even only n78 band, the issue remains. For example , the following cfg does not work.

// Scan band for finding cells function: "BAND_SCAN";

// Reception gain (integer) gain: 90;

// Bands list bands: (78);

// SSB period in sec. (optional, default is 0.02) ssb_period: 0.02;

// Logging level. (Trace recommended in current version) logging: "trace";

I paste the UHD version below, please check if there is known compatible issue with this UHD version.

Using configuration file $PWD/../config/scan_band.cfg

hello, did you install the cpufrequtils package ?

Hi I'm experiencing a similar issue. Ubuntu 22 with libuhd-dev version 4.1.0.5-3. I've gotten this software to function in the past on a Ubuntu 18 system.
