[srsran-users] srsenb failed due to no USRP rf detected

[Ralph A. Schmid, dk5ras]

Do the uhd tools load the FPGA image? On starting srsenb need to initialize the USRP and load it with the FPGA file...

Dear Team,

 

I was trying to build srsenb with srsepc with recent master version. I am using a USRP B210 RF with Ubuntu 18.04 PC for the same. The "uhd_usrp_probe" and "uhd_find_devices" works fine and can detect the RF device.

However, while running eNB, it fails with below error. Could you please help to suggest a solution/work around for this issue. I have already tried to give the proper image path for UHD, but no luck. Kindly help. Thank you.
