Let me just re-state things to make sure that I understand.

First of all ...
A VxWorks 6.4 image has been built. The floppy drive component has
been included (INCLUDE_FD), but the drive is not connected to the
board. That is, a component has been included for which there is no
connecting hardware. If this is a fair summary, why would you do
this?

Second ...
You say that this works in 6.4, but not in 5.5.1. Although I have not
tested this (perhaps someone else can verify), I would imagine that
the problem you report would also exist in 6.2 and 6.3 (but probably
not in 6.1). I am basing this on the fact the file system framework
was completely re-worked in 6.2. The floppy drive still uses the old
BLKDEV interface, but it has been wrapped in an XBD. I suspect (and
this is a suspicion only as I no longer have access to the VxWorks
source code) that the observed behaviour is related to that.

One other point ... With some of the 6.2 and later versions, if a
hard disk was included in the image (INCLUDE_ATA), and no hard disk
was connected to the board, the system would effectively hang as it
would wait and wait for a non-existant hard disk. This may be a
similar situation. I think that situation was solved with a timeout
with the XBD wrapper for the INCLUDE_ATA component (30 seconds?)

Hi Peter Mitsis,
Yes. The problem is in XBD Wrapper layer. The floppy is waiting for
sync
semaphore. I have changed the code to wait for 30 seconds. Then it is
working.

Thank you for reply.

Is it recommended value(30 seconds)? Whether it will give any
problem in
rare situtation?

-Thanks
