Yes, bringing this back up. Back to the original topic. When I get this FIFO ctrl error, the host is sending back
an icmp port unreachable msg to the usrp, I grab this using wireshark.
All I'm doing is running "uhd_usrp_probe". I've tried with and without adding the --args addr=<ip> parameter, same thing using both.
I've debugged a bit, and increased the ACK_TIMEOUT in usrp/usrp2/usrp2_fifo_ctrl.cpp from 0.5 to 10.0 and it literally just sits at:
Creating the usrp device with: ...
-- Opening a USRP2/N-Series device...
-- Current recv frame size: 1472 bytes
-- Current send frame size: 1472 bytes
<sits here for 10 seconds>
Then spits out
RuntimeError: RuntimeError: fifo ctrl timed out looking for acks
Again, there is a switch in between the USRP and the host.
