Hi, I am having a troubling error from my x310 USRP whenever I try to pull samples using the USRP source block. The error message I am getting is:
[ERROR] [STREAMER] The receive packet handler caught a value exception. ValueError: Bad CHDR or packet fragment WARN: USRP Source Block caught rx error code: 15 [ERROR] [RX FLOW CTRL] Error unpacking packet: ValueError: Bad CHDR or packet fragment The most basic flowgraph that creates this error is a USRP Source connected directly to a QT Time plot. It also happens when I try to run: 1) uhd_cal_rx_iq_balance, 2) uhd_fft, 3) uhd_cal_tx_dc_offset, My gnuradio version is 3.7.13.4, UHD version is UHD 3.14.0.0-88-g6013a511, and i have just reinstalled both to make sure it is not a software issue. I am able to successfully run uhd_find_devices and uhd_usrp_probe. I am also able to run a USRP sink block without error, if that helps identify the problem. Anyone have a fix for this? Andrew
