To control two ethernet PHYs individually with i.MX6SX.

[satoshishimoda]

Hi community,

I have a question about i.MX6SX Ethernet.

On MCIMX6SX SDB, two ethernet PHYs are used, but control signals (RST, INT MDC, MDIO) are shared PHY1 and PHY2.

Then, our customer want to control two PHYs individually.

In this case, how connect i.MX6SX and two PHYs? and how control two PHYs individually?

Can we use same connection as SABRE and can I control them with each PHY address?

Best Regards,

MDC and MDIO are the clock and data I/O signals of the RMII PHY management interface. They are common for both ENET modules. The PHY management interface can handle up to 32 PHYs simultaneously (the PHYs physical addresses should be configured differently in this case) and individually control them according to their addresses.

Have a great day,
Artur
