Hello @Sankar1,

 

Thank you for contacting the Intel Embedded Community.

 

According to Amston Lake EDS Addendum #721616, Section 7.8, Supported System Configuration, no Marvell 88E6393X is listed or validated.

 

Intel strongly recommends that only the PHYs listed be used in platform designs. Firmware and software incompatibilities may occur between other GbE PHYs and Intel’s BKC due to per-vendor or per-model PHY-specific programming requirements.

 

Best regards,
