Hey Bob,

Ok, I've found a work-around.

With a single transceiver link, when TTK starts, the tx channel, rx channel, and link are present in the TTK GUI. Those default links do not work. If I delete the defaults and recreate them, things work. In an attempt to understand this, I looked on the Altera KnowledgeBase and found articles stating that TTK expects the PHY at address 0 and the reconfig controller at 0x800.

I suspect that deleting the defaults and re-creating the channel resolves the issue with the "assumed" addresses of the defaults.

I'll change my addresses and see if the default channels work.

Cheers,

Dave
