Hi all, I am trying to get configuration cycles to work through an intel 21554 non-transparent bridge. I am not having very much luck so far. Everything else works great. I configured the Configuration Status and Control register (CSR offset 0x12) to allow downstream and upstream cycles (value 0x0202). But when I place anything in the config address register and then read/write the config data register, nothing happens on the remote side. I can see that the bridge doesnt even arbitrate for the bus. It just returns a failure. I cant seem to find anything else in the manual that looks like it needs to be configured before this is supposed to work. As a sanity check, I write to an address that the bridge is configured to translate and forward, and I can see this on the other side just fine. Its only the config cycles that seem to have a problem. Any suggestions would be appreciated! -Greg Haskins
