LAN not detected

[Altera_Forum]

Hello, 

 I am using Ethernet connection to transfer data from the development board to a computer connected to the board.  The problem is that the LAN is not detected after downloading the SOF file as well as the simple socket server design example unless we first download the SOF file of the UDP offload design example!.  Can any one advise us?  Thanks in advance.

If you are using a board with the Marvel PHY I think it is very picky with its reset signal. Try to see if there is any difference in the two FPGA designs in how the reset signal to the PHY is generated.
