There currently seems to be a timing issue with the frame builder. We switched over to using a symmetricom card to get an IRIG-B signal into the fb machine, but the gps time stamp is way off (~80 years Alex said).
If there is a frame buiilder issue, its currently often necessary to kill the associated mx_stream processes, since they don't seem to restart gracefully. To fix it the following steps should be taken:
Kill frame builder, kill the two mx_stream processes, then /etc/restart_streams/, then restart the frame builder (usual daqd -c ./daqdrc >& ./daqd.log in /opt/rtcds/caltech/c1/target/fb).
To restart (or start after a boot) the nds server, you need to go to /opt/rtcds/caltech/c1/target/fb and type
./nds /opt/rtcds/caltech/c1/target/fb/pipe
At this time, testpoints are kind of working, but timing issues seem to be preventing useful work being done with it. I'm leaving with Alex working on the code.
