Re: difference between vxworks 6.6 6.7 and 6.8

You should be able to find some relevant information via
(use the search box).

For VxWorks 6.6:

For VxWorks 6.7:

For VxWorks 6.8:

Not everything is listed on those documents though... What you really
want are the release notes but you probably need to be registered to
OLS to get them. Here is what comes to mind:

- VxWorks 6.6: Symmetric Multiprocessor (SMP) support
- VxWorks 6.7: VxWorks Source Build (VSB) and Overlapped Virtual
Memory for RTPs, as well as AMP support
- VxWorks 6.8: this is an "enhancements" release. Many enhancements
in many areas.
