Subject: ATF FB0 front-end rebuild 

 I've started work on updating the model for our front-end code.  First I want to just rebuild as it is using the existing model.  I'm going to put up idiot-proof instructions on the wiki as I go along.

So far I've tried the method given on the 40m wiki here: http://lhocds.ligo-wa.caltech.edu:8000/40m/Simulink_to_Front-End_code  .  I can get pretty far through these instructions before hitting problems at the point where you copy the .ini file across - at this point I find that the file is not in the location given in the instructions.

The simpler instructions on page 17 of T080135-00-C do work however.  I can get all the way through to the point where i do the startatf command and using ps I can see there are processes with the atf name running.  If I open an MEDM screen there is no data coming in though.  Also the daqd process wasn't running, so I did a sudo reboot on FB0.  When I did this FB0 hung while rebooting.  I power-cycled it and it booted up the next time.  When I ssh into it daqd is now running.  I did startatf again.  When I open MEDM the channels still don't seem to be acquiring.

I wonder whether there is a problem that it is not loading epics BURT data because in the /cvs/cds/caltech/target/c2atf/log.txt the final line, repeated over and over again is "Waiting for EPICS BURT 0"

When I try opening the GDS_TP medm screen it comes up with the error "cannot open file /cvs/cds/caltech/scripts/utilities/nova_logo.gif".  When I check, the utilities folder does not exist.  I tried to see where in the MEDM screen this .gif is supposed to live, but in the end I opted for putting random small gif file in nova_logo.gif in the meantime.  Now the MEDM screen runs without complaining but the boxes are white.
