Re: [USRP-users] Opening Vivado GUI during FPGA image build

2021-02-03 Thread Mark D via USRP-users
Thanks Wade, I had tried this just before your email. The first time I did this I got an error from make saying that Vivado wasn’t found in the environment and that I should run setupenv.sh. Running “source setupenv.sh” fixed this issue and “make E320_1G” GUI=1 did open the design up in Vivado

I notice in the second and subsequent runs, you get this message from UHD: [ERROR] [DPDK] All DPDK links did not report as up! One of the other issues I've noticed with DPDK (and unfortunately don't have an answer for) is that link detection seems to have issues. I'm not sure if this is an XL710-

Hi Aaron, Unfortunately, I already tried playing around with the link timeout increasing up to 10 seconds. No luck. But, I am presently troubleshooting the issue and trying to switch back and forth between DPDK and normal networking. I am finding that normal networking is not working after 1 run

Hi Aaron, Two things: 1) I am getting an error message at the conclusion of a successful run (see below). Not sure if this is something I should be looking at or if it is harmless. 2) I figured out a sequence of steps that can "fix" my broken state following a successful run. If I do the following,

I am now to the point where things are kind of working and I'm basically giving up trying to make them better. A few remarks for anyone who tries DPDK in the future (with N310, Ubuntu 20.04, Intel XL710 NIC, and UHD 4.0). 1) I can only get my application to run once and then I have to do some stu

Hi Rob, Thanks for documenting your steps. I can confirm most if not all of your problems on Centos 7, USRP N321, Intel XL710. @Ettus can we get some attention for this issue? DPDK is marketted as a huge improvement for max bandwidth applications, and I have failed to see any real testing or use c

I still cannot use a single 2-port QSFP+ NIC to connect to 2x N321s. Using the Intel tools to set the NIC to 2x2x10, the NIC doesn't recognize the second physical port as a valid connection to a USRP, but works as a loopback or a connection to another NIC. I asked Intel regarding the issues to see
