good morning , DMK URiX interface loss of connectivity
I have havd several all star nodes up and running using the DMK URIx interfaces each connected to thier own BeagleBone Black. Normally I see the green light on the URIx blinking at me. In the past few months I have seen where the light stops blinking. some times pulling the USB for 10 seconds and plugging it back in solves the problem. worse case a full reboot of the system. . now its only getting worse instead of better. and almost daily issue. I thought about the watchdog idea. but it monitors the read write to a file if I remember correctly. is it possible to rewrite the watchdog to monitor the pulses of the URI instead and act on the loss of pulses from the URI Mike AE4ML -- *"We must reject the idea that every time a law is broken, society is guilty rather than the law breaker.It is time to restore the American precept that each individual is accountable for his actions." ~ Ronald Regan*
Not sure if it's the same issue, but I had a similar experience with my BB-XM and LOX. Turned out it was my memory card. After reseating the micro SD, I've had no issues for a few months now. My BBB/URIx has been up and running on the original build for a long time now, without issue. Thanks, Bob kk6ecm Sent from iPad

No cable issues. No broken wires. I did pull the card and reseated it. Next plan.. I have ordered additional cards. Replacing the micro SD card this weekend. I'm just waiting for new cards to come in. Little more investigation showed the unit now when the light when out was totally dead. A total loss of pings to the BBB . Normally I could still access the BBB . So, I decided the best coarse of action is to replace the card and see if it miss behaves again. I have my test bed setup to see if it will fail in a 72 hr test this weekend. Mike Sent from my iPhone
