Dear TI Community,
When I use DP83620 in 100Base-FX mode I have trouble seeing an IP address at the CPU on the MII side of the PHY.
When I operate in 10/100BaseTx my CPU gets its IP address from the DHCP server without a problem and I can use a consul window to see the IP address. If I boot up the same PHY in 100BaseFX ie fiber mode then I can't see the IP address. The physical layer is fully functional. I can see from the far end that the link is up and operating on the fiber but it does not report an IP address ???
Is there some setting in the MII interface to the CPU that need to change when I switch from TX to FX mode? I'm using the boot-strap options for FX ENABLE. Is there any additional setting that I need to use?
Thank for your help!
