Re: Ubuntu 20.04 cannot find the Hackrf board?
Hi Cinaed, Thank you very much! I will check to see if I can do a more up to date hackrf version download.

Re: Problem seeing Hackrf One Hardware properly going through VirtualBox
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 -- Cinaed ** On 8/12/22 09:20, George Edwards wrote: 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: image.png 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 ?
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.
