Hi Daniel,
 
did you check if RST# is deasserted ?
As long as RST# is asserted, your REQ# is ignored by the arbiter.

Subject: MASTER GNT# not being issued in response to REQ#


Hello,
 
What requirements are there before GNT# will be issued in response to a REQ#
? (other than an idle bus)
 
Do any of the requesting boards configuration registers need to be in a
specific state, as there are several registers related to MASTERs.
 
Do all wintel mother board work with MASTERs ?
 
Does the PCI BIOS require anything ?
 
Does the OS require anything ? (drivers ??)
 
I just want to do the minimum neccessary to receive a GNT#. I have done none
of the above and it worked fine on another older wintel mother board however
I am not reciving a GNT# on a Aopen AX33 motherboard.
 
Sincerely
