Hi all,
Below is message from Antti. As http://xilinx.openchip.org can't be
accessed currently, I cannot but ask in this list:
I tried a day but still couldn't get the flash in the NuHorizons Spartan 3 400
board to work. Could somebody kindly tell me the EMC bug below and the
fix for it (btw, I'm using EDK 6.2.2)?
Thx in advance!
Cheers,
Tyrone

Hi
both 8 and 16 bit wide Flash configuration can be used with EMC, the
flash will be accessible for reads in 8/16/32 bit accesses
the A-1 terms comes from Flash manufacturer datasheet so it quite
normal naming :)
with flash write using CFI there are problems as the EMC has a bug
that prevents the writing. Simple fixup exists, we actually made even
special fixup core for that purpose
it is the EDK cores forum at
http://xilinx.openchip.org
the fixup is basically one or gate :)
