I'm using the Ettus provided UHD binaries (version 3.13.0.1-0ubuntu1~bionic1) installed from
deb http://ppa.launchpad.net/ettusresearch/uhd/ubuntu bionic main under Ubuntu 18.04.1 LTS with an USRP2 and WBX board. I get near the end of the execution of both uhd_usrp_probe and /usr/lib/uhd/examples/rx_samples_to_file the following error message: [ERROR] [UHD] Exception caught in safe-call. in virtual usrp2_fifo_ctrl_impl::~usrp2_fifo_ctrl_impl() at /build/uhd-YDOjRX/uhd-3.13.0.1/host/lib/usrp/usrp2/usrp2_fifo_ctrl.cpp:54 this->peek32(0); -> RuntimeError: fifo ctrl timed out looking for acks Any ideas what might cause this?
