Honored ContributorI have designed Cyclone V FPGA based board.
When i try to program, initial configuration is not working in Ethernet PHY. Can't see any LED glowing in Ethernet PHY. Hereby I have attached Ethernet PHY schematic. Please verify and guide me to clear this issue.
Honored ContributorUsing a Marvel chip on a custom board is really really not recommended because it is impossible to get the datasheet from Marvel... But now that the damage is done, I'd look for the usual culprits. Begin by testing the power rails, then the reset and clock signals with a scope, and then attempt MDIO communication with the PHY chip and see if you get any response.
