Hallo Guys,
We use an x310 device with ubx-160 daughterboards and we have several
custome RFNoC blocks on it. It works at the moment quite well but we
get at the end of the make() for a multi-usrp the following error:
[ERROR] [X300] 192.168.10.1 <http://192.168.10.1>: x300 fw
communication failure #1
EnvironmentError: IOError: x300 fw poke32 - reply timed out
It seems not to hurt us, but maybe we didn't detected the problem till
now :/
Does someone know, why this error happens? Actually we had an
FPGA-image without a ddc-block and there was no problem. But after we
also integrated the ddc-block, because we needed to manipulate the lo,
we got this error. Actually we've got the error twice, also after
initializing the radio-ctrls. But there we could solve the problem by
introducing a 1s wait until further initializations. So it seems,
maybe it's a bug in the make(), because they do not wait somewhere
enought long before further initializations? I have after the make
already a wait of 1s and also 2s didn't changed anything.
Many thanks for your help!

Do you get the same behavior with a "stock" FPGA image? What version
of UHD are you basing your RFNoC work on?
