Hello everyone,
I have been using a USRP B210 for 6 months now transmitting a home
DAB+ mux (with Open Digital Radio tools), and since this yesterday,
I'm stuck with this error and unable to broadcast again :
[INFO] [UHD] linux; GNU C++ version 8.2.0; Boost_106700; UHD_3.13.1.0-3

Error: RuntimeError: [ad9361_device_t] TX charge pump cal failure
I've tried with USB3 and USB2, second TX output, same problem.
As anyone had encountered this before ? It seems like a DC-to-DC failure ?
I post the question here as it seems more USRP related problem than
ODR. Even if I run the uhd_usrp_probe command, the same error is
displayed.
Any explanation/help is welcome :)

Another thing to check is the main power supply--are you running on USB
power or external power? If external, is the power-supply operating
correctly? (They put out about 6VDC).
