Revision 1.0

Introduction

This application note describes two methods for updating the software on the Soc 2MII Board and its -

predecessor – the SocTest Board. The two boards are essentially identical, and this document refers to them

both as the “SoC board”.

KSZ9692PB--EVAL PTPSoc Test BOARD

The SoCboard is intended to be used with the KSZ8463, KSZ8462 and KSZ8441 Eval Boards, which have the

following ordering part numbers:

KSZ8463MLI- EVAL

KSZ8462HLI- EVAL

KSZ8441HLI- EVAL

The KSZ84xx family of devices has hardware features to support the IEEE 1588 Precision Time Protocol (PTP)

standard, and the SoC board comes installed with Linux, KSZ84xx drivers, and one or more stacks that

implement the IEEE 1588 protocol.

From time to time Micrel may update the software image for the SoC board. Customers may choose to update the

board to the latest software revision, and are especially encouraged to if their SoC board software is an early

revision. Software revisions prior to the year 2013 do not fully support the production version of the KSZ84xx

silicon.
