MCSPU FULL RESTART PROCEDURE
J. M. Hill, version E, 16 February 2010
When things really go bad in the land of MCSPU, it may be necessary to reboot jet.
Here's the sequence of activities to get MCSPU running again. Operators should have already called for help before executing this procedure.
soft reboot from the command line
(login to jet) ssh telescope@jet
or press the reset button
or power cycle jet if all else fails
Reload the FPGA code
- when mcstemp and gotemp are not running
- This is only needed when you have powered off jet.
This Dan Cox command executes a series of commands like this to reload the FPGA code
for AZ, EL and Rotators.
/usr/local/dsp21ksf/bin/bitldr fpga0 -d1 -f ~dashby/lbt/mcs/top-archive/top-v110.bit
/usr/local/dsp21ksf/bin/bitldr fpga0 -d3 -f ~dashby/lbt/mcs/top-archive/top-v110.bit
/usr/local/dsp21ksf/bin/bitldr fpga0 -d 9 -f ~danc/reef_1brd_top.bit
Start the RPC server on jet
rpcconfig start 192.168.18.170
Start the MCSPU program "mcstemp" and the display program
Now you are back on the air, unless the encoders got zeroed at the same time..........they did get zeroed if you did "fpga load".
There is a serial console plugged into jet -- to access it use "telnet jet-cons.mountain.lbto.org 10001".
