README  2306 directory

Jan. 13, 2009  David Lawrence

This file refers to the /home/laser/2306 directory
on halldsc1.jlab.org, the host computer for the
FDC laser scanning system.

This directory contains files needed for the 2306 SBC
used to control the motors for the FDC laser scanning
device to boot up. The kernel files are in the kernel
directory.

  The vs4.o and fdc_laser_micah.o files are 
the drivers for the vs4 module. The source for these
is kept in the halld source repository here:

https://halldsvn.jlab.org/repos/trunk/home/davidl/FDC_laser/src/vxWorks

and on the controller host machine halldsc1 here:

/home/laser/FLATNESS/src/vxWorks


The file "startup" is the startup script for the vxWorks
SBC and is kept in the same directories as above. Note
that 2 copies of this file exist on the the host machine.
One in the source directory that is therefore linked to 
the svn repository and one in the 2306 directory that is
actually used by the working system. Changes to the working
system need to be copied to the repository by hand by 
explicitly copying the "live" version to the source directory
and committing it from there whenever changes are made.

The "misc" directory contains files left over from when
the system was being developed, but are no longer used.
