Honored ContributorThe dev kit uses a Marvell 88E1111 PHY for the Ethernet but getting it working in your own design is really rather difficult (and I haven't got it working yet....)
The PHY chip is has a data sheet which is hidden behind an NDA. This makes it rather difficult to work out what you need to do to get it working. The schematic states that the default setting is RGMII. However, this support doc says that it is SGMII http://www.altera.co.uk/support/kdb/solutions/rd12262011_851.html Which is correct? Who knows, as I can't get hold of a copy of the Marvell data sheet. To implement the fix requires knowledge of the address of the PHY chip. Fortunately, Dave WH has found this out: CONFIG[0] = LED_RX = 010b => PHY address [2:0] = 010b CONFIG[1] = LED_LINK10 = 110b => PHY address [4:3] = 10b So PHY address [4:0] = 10010b = 12h From: http://www.alteraforum.com/forum/archive/index.php/t-39638.html Thanks Dave WH More on my progress with this problem here: http://www.alteraforum.com/forum/showthread.php?t=44206
