Dear Community,
I am facing an issue with UHD 3.15.0 and USRP N310 since, sometimes, the
application (OAI gNB) does not start and returns this error:
[ERROR] [UHD] Exception caught in safe-call.
in ctrl_iface_impl<_endianness>::~ctrl_iface_impl() [with
uhd::endianness_t _endianness = uhd::ENDIANNESS_BIG]

RuntimeError: Failed to run enumerate_rfnoc_blocks()
I have noticed this error after I started the development with MIMO.
Rebooting the USRP resolves the issue but I would like to run the
application without rebooting the USRP every time.
Could you please provide me more info about this behavior?
Thank you.
Best Regards,
Federico Civerchia
