Re: [USRP-users] Why this oscillation in the received signal?

Andreas, Just a guess: Are both of your X310's using a common 10 MHz reference? If not, this is likely just the difference between the LO's on the two devices. Even tuned to the same center frequency, there will be a slight difference in the LO's. If you feed both X310's a common 10 MHz

OK, I see the first mistake. I was copying-and-pasting my notes for the E310 which had a different sysroot. Once I made the change to the proper one, it seems like it got past the rfnoc issue (or I haven't hit it yet with this new error). I am not getting: - Found PkgConfig:

[USRP-users] cross-compiling for N310

2018-12-17 Thread Jason Matusiak via USRP-users
Has anyone successfully created a new build for an N310 (RFNoC version in particular)? I was going to bring it up to date, but seem to be having issues. I ran: uhd_images_downloader -t sdimg -v To get the *.sh image for cross-compiling: oecore-x86_64-cortexa9hf-neon-toolchain-nodistro.0.sh

Bernd, I'm adding the usrp-users mailing list back to this conversation as someone may have more insight on this than I do. I was able to reproduce your CMake output by removing the Entry Values for *LIBUSB_INCLUDE_DIRS *and *LIBUSB_LIBRARIES. *If, in your CMake Entries, these have a big

EJ, I've tried a couple of different versions, but nothing worked. The most recent is: UHD_3.13.1.0-1-gd3b7e90a and in particular, commit: 494ae8bb0809. I guess I will try to poke around some more today. Thanks. - Original Message - Subject: Re: [USRP-users] does
