Re: [USRP-users] rx error code: 1

It looks like rx error code: 1 means UHD isn't getting samples from the SDR. I thought it was some sort of error that the UHD sink was configured wrong in gnuradio. I'm using a custom FPGA image that only transmits samples on certain conditions. I discovered I had a bad connector, so the second

I'm pretty sure you can't break the loader by changing the FPGA image. The cypress IC handles the loading. I've played around with the FPGA image a lot, including some broken images, and never had a problem loading a new image. On Mon, Aug 27, 2018 at 4:38 PM Javier Coronel (Expo Impex, S.L.) vi

I've build and installed UHD 3.10.1.1 on a Tegra TX2 (ARM64 platform). The USB 3.0 is working, but I'm getting errors with the USB 2.0 on a USRP B200. uhd_find_devices works, but uhd_usrp_probe, and the uhd application examples give the error below. Note that I've tried running with sudo, and ha

USRPs can do Tx and Rx at the same time. I did an experiment where I modified the FPGA image of Node 2 to send the Rx samples directly to Tx on a different freq., and measured the phase difference of the echo from Node 2 at Node 1. I didn't measure the phase difference of the carrier, rather the
