Thanks Dmitry.  I moved the store_results() to before the threads.interrupt_all().  It still crashes of course, but at least it writes the file. Lou On Jan 11, 2018, at 05:14 PM, Дмитрий wrote: I also had that issue. None of calibration utility worked. At the end of the procedure the

I also had that issue. None of calibration utility worked. At the end of the procedure they were all aborted. As a workaround I replaced threads.interrupt_all() and boost::this_thread::interruption_requested() to just set/get boolean flag. Perhaps it has something to do with boost. thanks, Dmi

[USRP-users] VITA time in X310 FPGA

2018-01-11 Thread Дмитрий Михайличенко via USRP-users
Hi, I am trying to understand timestamp tracking in FPGA and noticed one possible issue in axi_rate_change.v module . VITA time in packet headers is counted in ticks of master clock frequency, i.e. 200 MHz. For me it looks like axi_rate_change adjusts time by adding time from the first packet in

Good morning, We are trying to control two USRP B205i simultaneously on the same device (an ODROID XU4 running Ubuntu 16.04 minimal). Our goal is to launch two instances of our software on system power up (without the need of the user logging in into the OS), each one of them running a differe

[USRP-users] uhd_cal Aborted (core dump)

2018-01-11 Thread Louis Brown via USRP-users
I have a UBX160 in an X310 I'm attempting to calibrate.  It crashes at the end and never writes the cal files in ~/.uhd.  Does this for all 3 cal routines; TX IQ, RX, IQ, and TX DC.  Does it on two separate X310 on two separate machines. Any idea what's wrong?  For reference: https://githu

Hi Ale, I've added back on the list. It's usually best to keep the list included so you can get faster responses from a larger group of experienced people. That example isn't installed into the default PATH like the core UHD programs are. The binary can be found at (by default on Ubuntu) /usr/loc

Re: [USRP-users] RFNOC design question

Martin- Just an update. It works now. On a whim based on your comment below I decided to rebuild with a larger input buffer on the input port of the noc shell. This fixed it. Originally it was set to 11 which is what the noc shell template is. I looked at the Ettus duc and it had 12 set for thi

[USRP-users] GNURadio FFT Plot and UBX Maximum Input Power

Hi to all, I have an X310 USRP and a UBX-160 on it. There is also an antenna connected. I am transmistting some signal by a handheld radio and plotting the FFT plot of IQ data in GNURadio. It seems that power reaches almost 0dB. If I close too much the spectrum fluctuates, it does not look good. I
