Just to be sure can you tell me how you pinned out the PCB footprint. Does it match this picture looking fr... - 03:57 PM FPGA Development: RE: TLK100 Ethernet
Mike,
After talking this out with our software guy we are convinced its as your said,one of two things. The con...- 03:49 PM FPGA Development: RE: TLK100 Ethernet

858-254-0008
- 08:20 PM FPGA Development: RE: TLK100 Ethernet
- That message is OK. You can set up ethernet to use MII or RMII (but not both, and you're using MII).
It looks lik... - 08:06 PM FPGA Development: RE: TLK100 Ethernet
- I saw this among the test
EMAC: MII PHY configured, RMII PHY will not be functional
I attached the whole text - 07:50 PM FPGA Development: RE: TLK100 Ethernet
- Can you dump out the text from the boot sequence? Does the u-Boot locate the PHY (via the MDIO scan)?
