Re: GRC: Cannot find "RFNoC Fosphor" blocks

[Bachmaier, Luca]

Hey everyone,

 

I was able to solve this problem now: my installed version of GNU Radio (3.10.5) simply didn’t contain the Fosphor blocks. After removing this version and installing GR 3.10.7 from source the blocks are now available in GRC. (See release notes for GR 3.10.6, “gr-uhd” https://www.gnuradio.org/news/2023-07-19-gnuradio-v3.10.7.0-release/)

 

So far I’m struggling with getting Fosphor to start, Error “[!] CL Error (-1001, …): Unable to fetch platform IDs”. I wasn’t able to find any up-to-date help about this online. How did you install Fosphor / OpenGL? I’m using a AMD CPU and since AMD stopped supporting OpenGL I had to switch over to POCL.

 

Regards

Luca

I'm not sure about UHD 4.3, but the blocks are available for me with UHD 4.4 and GR 3.10.

However, the RFNoC Fosphor display block bogs down the GUI so much that it's practically unusable.  I haven't been able to look into what's wrong, or whether I'm doing something wrong though.

Hi Johannes,
     
thank you for your reply. Where can I find this module? The gr-ettus module (https://github.com/EttusResearch/gr-ettus) is apparently not required for 3.10, on the site it says "Use gr-uhd directly".

That aside I'm installing GNU Radio 3.10.7 right now which should contain the RFNoC Fosphor blocks (as opposed to my current version 3.10.5).

Luca

Hi Luca,

you need to install the OOT module that includes the RFNoC version of
fosphor.

Cheers
Johannes

 Hey everyone,

 I’m currently implementing a flowgraph that uses RFNoC by UHD / Ettus
 Research. In GNU Radio companion, I noticed that there are no blocks
 “RFNoC Fosphor Block” and “RFNoC Qt Fosphor Display” available (See this
 workshop https://www.youtube.com/watch?v=M9ntwQie9vs
 <https://www.youtube.com/watch?v=M9ntwQie9vs> @ 22:13 for a

flowgraph

 that uses them). My basic software setup is:

 -OS: Debian 12

 -GNU Radio 3.10.5.1

 -UHD 4.3.0.0+ds1-5

 I was wondering why these blocks aren’t available or if I need to
 install an additional module in order to get them. The module gr-fosphor
 (https://projects.osmocom.org/projects/sdr/wiki/Fosphor
 <https://projects.osmocom.org/projects/sdr/wiki/Fosphor>) just installs
 the “standard” version of Fosphor, **not** the FPGA / RFNoC

implementation.

 Thank you and regards

 Luca
