We have used VxWorks here since 1986. We have been very happy with it
since it takes care of all low level functions we need (NFS, rlogin,
telnet, sched, I/O) it looks (almost) like UNIX (I have often converted hundreds of
lines of UNIX C code with only some header changes and the replacement
of a few timing related functions like getitimer).
Their software support has been great. When I had some problems last
year with the VME TCP backplane driver (used to pass TCP/IP to boards
across the backplane that lack enet interfaces) I was readily given the
source and I sent back my fixes.
Unfortunately, there is one area in which I have recently become
dissatisfied with Wind River. Perhaps a year or two ago, Wind River
lawyers came up with the idea of restricting a development license
($15,000) to a specific "project". While the definition of "project"
is not at all clear, the pessimistic view is that any time you start
something new you pay an extra $15,000. I find this pessimistic
definition unnacceptable in an environment were we frequently get
$20,000 jobs to do some experimentatiion. I am trying to come to an
accommodation with WRS over this because we love their software, but
so far I haven't gotten very far.
