Hi everyone,
We have a very odd situation with our Roach 1 board and i was wondering
if anyone has seen something like this before, or had ideas on what to
check.
We are having problems with a close to production receiver, and I setup
a test bed in the lab that recreates the issue. I have a simple bof
running on the FPGA, and a custom mode for the tcpborphserver2 that
transmits (fake) data via UDP to a client machine (in this test-bed
there is no interaction with the FPGA for what data to transmit). A
simple UDP client process receives the data and exits. When I then stop
the data transmission on the tcpborphserver2 the entire roach nearly
freezes up: PING times go up to nearly a second, and the roach is
extremely sluggish, even when we are logged in via the serial connection.
Once the roach gets into this state, we have had no luck finding
anything that might be causing it: CPU and memory usage looks normal, no
traffic viewed from tcpdump that causes alarm. Does anyone have any
idea what could be freezing up the roach like this, yet not appear to be
using up cpu or memory?
thanks
Paul Marganian
