Gwen, Wow, it was only 15 days ago too. The coincidence! Yes, that is the exact problem. Thank you! I have got mine compiled and I can see that it did build the converter for the neon. Kevin On Fri, Nov 10, 2017 at 2:07 AM, Gwenhael Goavec-Merou via USRP-users < usrp-users@lists.ettus.com> wrot

I guess this is a little late, but you can pass in compiler flags on the command line with -DCMAKE_CXX_FLAGS. For example: cmake -DCMAKE_CXX_FLAGS:STRING="-mfloat-abi=hard -mfpu=neon -mtune=cortex-a15" ../ Ron On 11/10/2017 12:07 AM, Gwenhael Goavec-Merou via USRP-users wrote: Hello, maybe

I've some difficults to understand because the piece of code impacted by this patch is only use if HAVE_ARM_NEON_H is true. Then I suppose if the CPU is an ARM but has no neon this test is false and then this part is not used. It's seems logical because c and asm files added in this section are neo

Hi Ian, OK - is there code for the dissector available to build a new version? Or do you think it's worth it? Also - our host sending the samples was actually only 1Gbps ethernet (we weren't using the 10Gbps card for that), so I'm not sure that the samples would be going into the switch fast

Kevin, I wouldn’t expend more effort at the moment on the dissector, the UDP ports and packet sizes pretty much tell you whats going on if you understand UHD. It may be that the dissector for the old UHD protocol was never complete/perfect. Interesting that it was the monitoring port that was 10

Re: [USRP-users] TX power levels. Long term exposure.

2017-11-10 Thread Arjun Bakshi via USRP-users
Wanted to further clarify something. Do you mean that a usrp will in most cases stay below acceptable levels, or that my specific setup is safe? Like TX at 520mhz makes the snr much higher compared to that at 1.2GHz. Thanks AB Bakshi, Arjun wrote > > >Thanks for clearing that up. >

There is nothing you can do with a USRP to expose you to harmful levels of RF energy. You would need to add an amplifier. On Fri, Nov 10, 2017 at 11:04 AM Arjun Bakshi wrote: > Wanted to further clarify something. Do you mean that a usrp will in most > cases stay below acceptable levels, or that

My fix will be in a file which has a GPL copyright notice, so I think there won't be a problem with it. Still, it might be a good idea to include the license in the root directory of the repository. It's recommended e.g. by GNU GPL how-to. 2017-11-09 16:33 GMT+01:00 Michał Wróbel : > Hi Manuel,
