Ethernet MDIO driver

sgp_118 — Thu, 05 Nov 2020 06:59:49 GMT

Hi All,

I have a board where only the Ethernet MDC and MDIO lines are connected to S32K148 controller and the data lines are connected to a different application processor. The S32K controller is supposed to only initialize the PHY.

For this I am looking for a sample MDIO driver, that can be used for setting up only the MDC clock and read/write over MDIO interface.

I couldn't find any such example codes in S32DS. Can someone please help with this?

Thanks in advance.

Regards,

Guru

Hi,

what about "phy_tja1101_s32k148" demo example. Could this be helpful?

It shows MDIO communication with TJA1101.
