> Is this an Altera FPGA ?
Thanks Michael,
I probably should have ellaborated a little more.  It is an Altera FPGA
as it happens, but it's irrelevant really because I'm running uClinux on
an ARM processor talking to the FPGA, so I could have said simply
"device".  There is no NIOS or Avalon buss involved.  The function of
the FPGA is naturally 32 bits wide so I don't want to alter it just to
allow it to accept byte wide accesses (I don't think we have connected
byte strobes to the FPGA in any case so it would be impossible with the
hardware without nodification).  I have just realised that this sort of
thing is done using ioctls in LDD3 so I may have found an answer to my
own (perhaps slightly premature) question.  Sorry for the newbieness.
