Hi all, I am running a simple application where I am receiving and transmitting on both channels of multiple USRPs. I recently updated to the latest version of UHD (3.14) from v3.11, and now I can't run my program without getting the following errors:
[ERROR] [X300] 192.168.40.2: x300 fw communication failure #1 EnvironmentError: IOError: x300 fw poke32 - reply timed out [ERROR] [X300] 192.168.40.4: x300 fw communication failure #1 EnvironmentError: IOError: x300 fw poke32 - reply timed out [ERROR] [X300] 192.168.41.3: x300 fw communication failure #2 EnvironmentError: IOError: x300 fw poke32 - reply timed out [ERROR] [X300] 192.168.40.2: x300 fw communication failure #2 EnvironmentError: IOError: x300 fw poke32 - reply timed out [ERROR] [X300] 192.168.40.4: x300 fw communication failure #2 EnvironmentError: IOError: x300 fw poke32 - reply timed out [ERROR] [X300] 192.168.41.3: 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: 192.168.41.3: x300 fw communication failure #3 My MTU size is 548 bytes (for low latency), I am using 10G ethernet, and my max buffer size is 50000000. UHD does give me a warning requesting larger recv buffer sizes, but the requested sizes are larger than what is allowed on my host machine, and increasing them doesn't seem to get rid of this error. Any help would be appreciated. Thanks, Jessica Iwamoto Member of Technical Staff The Aerospace Corporation
