SPI over Ethernet (LAN9250V)

[Ranjitha]

Currently am Working on STM32H7x series , A'm confused regarding the importance of SPI for Ethernet(LAN9250V/ML) we have to use external bridge for communication. Give some samples codes to implement this perticular Ethernet

SPI has nothing to do with Ethernet as such.

The LAN9250V is an Ethernet controller which happens to have an SPI interface:

Note that it's a Microchip product - so nothing to do with ST.

Is This is supported to stm32 controller, because SPI over Ethernet is Microchip product. Actually, what am trying is it is for POC so this is supported or not please confirm.

[Ranjitha]

please give Some APIs to Achieve this POC

Microchip would be the ones to ask for that.

The key thing to remember is that the LAN9250 neither knows nor cares what microcontroller you use - it simply behaves as described in its datasheet.

So any driver code should be portable to an STM32.

Look for support in whatever IP stack you use.
