Hi Cinaed,

Thank you very much! I will check to see if I can do a more up to date
hackrf version download. George

Re: Problem seeing Hackrf One Hardware properly going through VirtualBox

2022-08-14 Thread Cinaed Simson
Okay, this output looks better -  it appears you now have the libraries 
installed.


I don't understand the output

   Board ID Number: 2

If you have more then 1 board installed, unplug all the boards except 
for 1 board.


To run multiple boards you need to use serial numbers - but you need to 
get hackrf_info working correctly.


Type

   groups | grep plugdev

If it doesn't print anything, you need to add yourself to the group 
plugdev.


To do that use

   sudo usermod -a -G plugdev 

where  is your login name.

Then logout and then login again and type

  groups

and you should see an entry for plugdev.

And then run

  hackrf_info

Hello GNURadio Community,

I designed an FM receiver in Gnuradio-Companion to receive an FM 
broadcast signal from the Hackrf One. I am running Gnuradio-Companion 
3.9 on Ubuntu 20.04 inside VirtualBox 6.1. I installed the Hackrf 
software on Ubuntu and set VirtualBox USB port to see the Scott Gadget 
Hackrf One. Problem is: when I execute the command "hackrf_info" in 
the Ubuntu Terminal, it reads the Board ID, Firmware Version, and Part 
Number, but says the hackrf_info version and libhackrf version are 
"unknown". This is a snapshot of the terminal response from executing 
the hackrf_info query:

I cannot find any info online to solve this problem (allow the 
Terminal query “hackrf_info” to return all the board information). As 
a result when I run the GRC flow graph, it fails because it cannot 
open hackrf. I would appreciate any suggestions.


Thank you!

George


[VOLK] a += b*c ?

2022-08-14 Thread Randall Wayth
Hi Folks,

Hopefully I am just missing this, but is there a kernel that does
vectorised a += b*c ?

Something like the IPP "AddProduct" function?

Cheers,
Randall.
