[USRP-users] X310 Power before Transmit

2019-02-25 Thread Alexander Olihovik via USRP-users
Hi all, I modified the X310's FPGA to toggle a GPIO pin immediately once it sees TX data, and delay the TX data by a fixed number of samples. Using an oscilloscope, I found that everything works as expected, but there is an initial spike of RF power that precedes the GPIO trigger and the RF

[USRP-users] X310 FPGA IQ Samples

2018-12-19 Thread Alexander Olihovik via USRP-users
Hi all, I'm trying to work with IQ data on the X310 right as it leaves the FPGA to be transmitted, and also as soon as it is received from the daughtercard. Is "capture_ddrlvds.v" and "gen_ddrlvds.v" the right place to do this? Best, Alex ___

Hi all, Will running "make X310_HG" generate a .xpr file that I can open with Vivado? I have a .xpr for the E310 from a previous effort so I think it can be done, but I wasn't the originator of this file. I was following this guide: http://files.ettus.com/manual/md_usrp3_build_instructions.html

I've been following the guide for rebuilding the file system at https://files.ettus.com/manual/page_usrp_e3x0.html. When I try to build an image with 'bitbake gnuradio-dev-image', I get the following error: ERROR: Function failed: do_compile (log file is located at
