I have an RFNoC flowgraph and bitfile combo that used to work but is erroring out now. I've been using the code successfully on the E320 and E310 and decided to re-build for the X310 (and XG flowgraph). When I run my flowgraph, I am see a lot of addition debug that I am not used to seeing (which is fine) and then my block in particular seems to cause problems and I get the error in the subject. I am guessing that since I just rebuilt everything, some change needs to be made in my impl for my block due to some UHD update, but I can't quite figure out anywhere where something changes. The beginning of the output when I run my flowgraph is:

And finally, if I let it sit there, the X310 must get into a wonky state because I start to get: [ERROR] [X300] 192.168.80.2: x300 fw communication failure #1 EnvironmentError: IOError: x300 fw poke32 - reply timed out [ERROR] [X300] 192.168.80.2: x300 fw communication failure #2 EnvironmentError: IOError: x300 fw poke32 - reply timed out [ERROR] [X300] 192.168.80.2: x300 fw communication failure #1 EnvironmentError: IOError: x300 fw poke32 - reply timed out [ERROR] [X300] 192.168.80.2: x300 fw communication failure #1 EnvironmentError: IOError: x300 fw poke32 - reply timed out [ERROR] [X300] 192.168.80.2: x300 fw communication failure #2 EnvironmentError: IOError: x300 fw poke32 - reply timed out [ERROR] [X300] 192.168.80.2: x300 fw communication failure #3 EnvironmentError: IOError: x300 fw poke32 - reply timed out [ERROR] [UHD] An unexpected exception was caught in a task loop.The task loop will now exit, things may not work.EnvironmentError: IOError: 192.168.80.2: x300 fw communication failure #3 EnvironmentError: IOError: x300 fw poke32 - reply timed out What am I missing here?
