Re: [Discuss-gnuradio] uhd_fft.grc: fifo ctrl timed out looking for acks

[Marcus Müller]

Hello Maria,

the reason I most often encountered for this is that in the middle of operation, Ubuntu decided to reconfigure the network interface. Make sure you set the network interface to a valid address from the 19.168.10.XXX network (except .2), and configure the network manager for "static" addressing.

also, for some reason, your USRP's subnet mask as reported by uhd_usrp_probe seems wrong; it should be something like 255.255.255.0, not 255.255.255.255.

By the way, what is your network card? (you can find out by doing "lspci|grep -i ether", usually)

Best regards,
Marcus

Hello,

I have the following system configuration:

Ubuntu 14.04, 64-bit, 3.17.0-lowlatency

Gnuradio v3.7.8

and a USRP N2930, with UHD_003.009 version installed.

The script uhd_find_devices works properly and the output of uhd_usrp_probe is the following:

When I execute the uhd_fft.grc flowgraph, the program runs for a few seconds but suddenly freezes, showing the following output in the terminal:

Could you please give me some guidelines to solve this issue?

Best regards,
