Hi Dirk,

Generally, vxWorks 6 has some new features (e.g. real time processes) which
are not used by EPICS. vxWorks 6 still supports running applications, e.g.
EPICS, in "kernel space" (which is all you had in vxWorks 5). However, the
vxWorks shell has changed a bit and not everything that worked in vxWorks 5
startup scripts might work in vxWork 6 startup scripts (I had difficulties
sourcing other scripts). I think I can tell more once I have the MVME4100
running.

I wonder if your sourcing scripts problem is the the same issue we found when we upgraded to vxWorks 5.5.2 - if you use the construct
    ld < ioc.munch
in your startup script then all subsequent shell redirections to source other scripts get ignored. The solution is to replace the above line with this
    ld 0, 0, "ioc.munch"
which permits later shell source commands to operate normally. I think it's highly likely that Wind River broke both versions of the target shell at the same time...
I am also not having problems with this.
However, in the beginning I bumped into this as well.

We are using vxWorks 6.6 on some projects here at SLAC:

Using the vxWorks project facility please do the following:
================================================================================
vxprj parameter set SHELL_COMPATIBLE TRUE
vxprj parameter set SHELL_TASK_OPTIONS "(VX_FP_TASK | VX_UNBREAKABLE | COPROCS_ALL)"
=================================================================================
I had to make similar changes when I was at the SNS as well.

Thanks,
Ernest
