KSZ8794 4-port ETH switch to MX8M

Hi All,

I am unsure if how to wire Phy to a i.MX8M procc in RGMii mode of operation.

I am using a SOM from Variscite MX8M as the procc module.

The module has its PHY removed, with pins exposed as per the attached schematic.

 

Attached are the 2 schematic files.

 

Particularly my concern of the J1.1 on sch > main  >> ENET_PHY_REFR_CLK

 Does it need to connect somewhere to the PHY ?

 

Res strappings A>>E on PHY sch?

 

Any other apparent faults in the wiring?

 

Has anybody got a linux driver for this device, to share? (yocto)

 

Any advise and input will be appreciated.

 

Thank you.

 

Regards,

Gerhard
