Description
ETH0 interface
On BORAEVB, there is a mistake in the
connection of the center tap pins. They should be
separated from one another and connected
through separate 0.1 F common-mode
μ

connection and selection of the magnetics),
please refer to the Micrel KSZ9031RNX
datasheet)

The DDR3 SDRAM bank on the BORAEVB is not
supported in this BELK version
