[srsran-users] Request for a help

[Eddy Higgins]

To add to Justin's reply...
Note that depending on the OS and UHD version you are using, sometimes that
script is installed in a different location...

For me (Ubuntu 20.04 LTS server) it's installed under (*/usr/lib/uhd*):
usrp:~$ find /usr -type f -iname uhd_images_downloader.py
/usr/lib/uhd/utils/uhd_images_downloader.py

If you have already run this and are still having problems ...

You can check where it is looking for the images with: *uhd_config_info
--images-dir*:
usrp:~$ uhd_config_info --images-dir
Images directory:

If that is empty you may have to set the *UHD_IMAGES_DIR* environment
variable to the location of the images

usrp:~$ export UHD_IMAGES_DIR=/usr/share/uhd/images/
usrp:~$ uhd_config_info --images-dir
Images directory: /usr/share/uhd/images/

Now you should be able to see the uhd device...

usrp:~$ uhd_find_devices
[INFO] [UHD] linux; GNU C++ version 9.3.0; Boost_107100; UHD_4.1.0.4-release
--------------------------------------------------
-- UHD Device 0
--------------------------------------------------
Device Address:
    serial: 31234567
    name: B200mini
    product: B200mini
    type: b200

I would typically set the environment variable in my .bashrc or in the
calling script I might use
Alternatively you can also specify the environment variable on the fly when
you run. e.g:
usrp:~$ UHD_IMAGES_DIR=/usr/share/uhd/images/ uhd_find_devices
or
usrp:~$ sudo UHD_IMAGES_DIR=/usr/share/uhd/images/ uhd_find_devices

I hope this is helpful,
Regards,
Eddy.
