PNP Serial Ports

Has anyone had issues with COM Ports being setup properly on XPe FP2007?
The reason I ask, is that I have a new SBC with 6 ports built on the board.
XP Pro seems to install them properly, but on XPe, I end up with some really
weird results.

Sometimes, I end up with Com1, 2, 3, 4, 4, 4
Then if I delete the ports and reboot I may end up with COM1,2,3,4,4,5
This keeps up and finally they will come up properly named, but COM5, 6 will
come up as disabled - Out of Resources or Address Conflict.

With XP Pro, they come up as COM1 - 6 and work fine.

Thanks in advance for any ideas,
Richard
 
No ideas on where to look or what might help fix this. I'm needing to
deploy an image and kind of stuck.

I feel your pain. I have had some really weird things happen with the
later updates to XPe. The most recent was the centre and sub-woofer
sound outputs were not working, on one target only. There was a missing
dependency that TD was not picking up. I'm still not sure what it was.
I just added a whole bunch of components from a working image, none of
which appeared to have any relationship to audio.

This is not the only time I've had these sorts of problems with the
later XPe updates. Probably has something to do with how the
dependencies have been cut back. In SP2 and earlier, I couldn't build a
small image without having 20 or so unresolved dependencies.

I suggest that you might have a similar issue - a dependency that TD is
not picking up.
 
If the ports work properly on an XPPro machine it might be a driver issue.

On the XPPro machine look at the driver files used by the COM ports in the
device manager. (get the full list of files not just the first file).

Then in target designer use filters to find componenets using those files
and make sure they are all included in your image.

I've seen this with a standard PNP machine with just two serial ports. Both
of them come up in device manager as COM2. Delete both of them and re-boot
and they come up as COM1 and 2.

I suspsect there is something weird going on with the COM port ennumerator
during FBA. On our system i'm convinced it's something to do with the touch
screen system we have 'claiming' COM1 for the touch screen before COM1 has
been added to the system.
