We use our RoboRio on our practice bot and this week we encountered a problem where sometimes the RoboRio will disconnect from the DS and won’t go back online unless we reboot it. We tried reimaging the RoboRio but that didn’t help.
We then replaced our RoboRio on the practice bot with a spare one, but that didn’t help either.
In order to help you help us more I took the first RoboRio (the one that is no longer on the bot) aside and connected it only to a 12V power supply and a laptop (through USB or Ethernet). I managed to recreate the problem (which was very hard as it happens randomly) and gather some info.
The first thing I see when the problem occurs is this (laptop is connected to RoboRio through USB):
I can see the USB is recognized but no other signs of communication.
All other adapters are disabled:
I cannot ping the RoboRio:
I try to disconnect the USB and reconnect it, but now it is not recognized anymore:
The adapter is gone:
Windows complain that the USB device is not recognized:
The RoboRio thinks everything is good:
Even when not connected at all:
Ethernet connection doesn’t work either:
Can’t even ping:
Back to USB, I reboot the laptop and it doesn’t help.
The RoboRio Imaging tool can’t find the RoboRio.
I took the logs out of the RoboRio (from /var/local/natinst/log/). I couldn’t find anything in them, but maybe you can:
