Ethernet PHY with OSD32MP1-BRK

[Ray Ring]

Will the OSD32MP1-BRK support connection with an ethernet XCVR and magnetics to protype 10/100 ethernet? The hardware design seems straight forward but I am not that familiar the with Linux OS and I am wondering what I would need to do on the software side to configure. The RED development board provides good information as to hardware integration but I did notice one pin used on the RED board for the ethernet interrupt is not brought out to a connection point on the BRK board(A3/PA13).

Ray,

Since the only option for MII_COL is either PA3 or PH3, it won’t be possible to add 10/100 Ethernet to the BRK. However, RGMII configuration is possible.

Best,

Neeraj

 

Adding the RGMII configuration pins:

PD24 — ETH1_MDIO

PC24 — ETH1_MDC

PD22 — ETH1_RX_DV

PC20 — ETH1_RX_CLK

PC21 — ETH1_RXD0

PC19 — ETH1_RXD1

PD21 — ETH1_RDX2

PC11 — ETH1_RXD3

PD10 — ETH1_TX_EN

PC06 — ETH1_TX_CLK

PC07 — ETH1_TXD0

PD08 — ETH1_TXD1

PD14 — ETH1_TXD2

PD07 — ETH1_TXD3
