[USRP-users] Re: RX Frequency Tuning Questions

Jim, just a quick follow-up. There was indeed a bug with the lo-lock sensors which was fixed in https://github.com/EttusResearch/uhd/commit/f36c267fc9ca908032fb719ec318c142636f (see also https://github.com/EttusResearch/uhd/issues/534). Both the name mismatch (lo_lock vs. lo_locked) and the la

Hello sp h, I did it about 3 years ago, as I remember, there is a Tcl file in the make folder or s.w else the Vivado version is defined there, you need to change the Vivado version there. Please keep this in mind, in some scenarios the Vivado version must be exactly the same as configured in the m

[USRP-users] Re: RX Frequency Tuning Questions

Martin, Thanks. On Friday, one of my coworkers saw something on github about the lo_locked sensors being fixed. So, that is good -- thanks for pointing that out. Regarding your other comments about timed "future tunes" on the E320: you mentioned that the E320 doesn't let you do those. That is w

[USRP-users] Re: Timed Commands Not Working

Thanks Dustin and David -- that is good info regarding UHD versions that worked or didn't work with the test_timed_commands example application. David, I'm not sure of the answer to your question regarding get_time_now() and blocking . . . now that you got me thinking about it, I'm a little conf

Hi sp, Regarding the error message about Vivado not being found. You need to set up your environment before building an FPGA. rfnoc_image_builder does this automatically for you. But if you run make directly then you need to source setupenv.sh manually. For example: source uhd/fpga/usrp3/top/x300

Thank you for the clarification. When I used these commands: source setupenv.sh --vivado-path=/home/sp/xilinx/Vivado rfnoc_image_builder -F /home/sp/Documents/uhd-4.1.0.5/fpga -I /home/sp/Documents/rfnoc-tutorial/include/rfnoc -y /home/sp/Documents/rfnoc-tutorial/rfnoc/icores/gain_x310_rfnoc

[USRP-users] E320 with 1Tx and 2RX

Hi, What does the following error mean for an E320? In my application, I want 1Tx and 2Rx. [ERROR] [0/Radio#0] Invalid channel configuration: This device does not support 1 TX x 2 RX or 2 TX x 1 RX configurations!

[USRP-users] Why RFNOC gain example building FPGA, I faced with module 'rfnoc_block_gain' not found?

I copied RFNOC gain example from UHD folder, I installed it successfully in Gnuradio, But for building FPGA I was faced with these errors. How can I solve this problem? Thanks in advance ERROR: [Synth 8-439] module 'rfnoc_block_gain' not found [/home/sp/Documents/rfnoc-tutorial/rfnoc/icores/x310_
