Thanks for the information. we would be surprised if it wasn’t a
hardware issue.
A more full story is that we have three systems deployed and are not
physically accessible (and not returnable) so that we cannot do any
hardware diagnostics. The other two systems have died and are not
visible on their network interfaces. They actually died before
deployment but the team responsible for the enclosure and power supply
sequencing failed to let us know prior to the deployment date that
they were non-functioning. One of these we have tried to recover
through JTAG reprogramming but no success there. As for this last one
that was working at the time of deployment, a insignificant
(incidental) amount of investigation showed that the power sequencing
affected whether or not the x310 was functioning. Now it appears but
is failing with the error as described. The people responsible for the
enclosure also made it exceedingly difficult for us to do even
software diagnostics by choosing a USB port for their convenience
rather than the alternative one we specified resulting in limited
access of the processing platform (that is running gnu radio) so that
the only thing we can do is insert a USB drive with arbitrary code on
it which will get executed when the power is cycled. This makes
reprogramming UHD difficult and treacherous. We only have access to
these systems in this way for one more day, so everything is looking grim.
Personally, I suspect that the power switching has fried 2 ½ x310s and
this project is a dead loss for us.
thanks - JP
It would be useful to the rest of us to know exactly how you believe the
power sequencing led to the failure of these devices.
I understand, given the domain of use, that such information may not
be readily available.
But if the power-sequencing to an X310 can fry it, I think this
community would surely like to know how...
