Additional notes on networking:
Care needs to be taken when editing these files on the device, since
vi
/
vim
sometimes generates undo files (e.g.
/etc/systemd/network/sfp0.network~
), that
systemd-networkd
might accidentally pick up.
•
Temporarily setting the IP addresses or MTU sizes via
ifconfig
or other command line tools will only change the value until the next reboot or
reload of the FPGA image.
•
If the MTU of the device and host computers differ, streaming issues can occur.
•
Streaming via SFP0 at 1 Gb rates requires a MTU of
1500
•
Streaming via SFP0 at 10 Gb rates requires a MTU of
9000
•

The FPGA image should match the version of UHD installed on the host computer, when operated in Network mode. Connect the device to the host
computer using either the RJ45 or SFP+ port, refer to the section above for detailed instructions.
To obtain all the FPGA images for a specific version of UHD, run the following command on the host computer with internet access:
$ sudo uhd_images_downloader
Example Output:
$ sudo uhd_images_downloader
