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)?
