Re: Old design R2000 and Realtek RTL8019AS duplex issue

Pete,

I did some searching and this post seems to summarize the Realtek issue (independent of the Rabbit's use of it) fairly well:

My understanding is that you can configure the Realtek chip for full duplex, but won't negotiate that with the switch.  You would need to manually configure the switch port for full duplex as well.

Perhaps you could push back to your customer on what the perceived gains are from getting your embedded device to run at full duplex.  The Rabbit 2000 is the bottleneck here, and switching to full duplex isn't going to result in huge performance gains.

You could see whether forcing the port to full duplex results in the interface working correctly.
