SPARC M7 Series Servers : CMIOU FPGA firmware update (Doc ID 2085049.1)

Last updated on JANUARY 03, 2022

Applies to:

SPARC M7-16 - Version All Versions to All Versions [Release All Releases]
SPARC M7-8 - Version All Versions to All Versions [Release All Releases]
Information in this document applies to any platform.


The goal of this document is to describe how to upgrade the CMIOU FPGA Firmware on SPARC M7 series server.

The platform should be running SysFW 9.5.2.g or higher.

Note that several components of the SPARC M7 Series Servers are using FPGA. Those components must be running the latest version.

The following table provides the list of components and the respective latest versions available.

Platform Type Component FPGA Version
M7-16, M7-8 with one or 2 Pdoms CMIOU  X.3.8.3
M7-16, M7-8 with one or 2 Pdoms SP
M7-16 SPP
M7-16 SWU  Y.2.0.5

Where X and Y can be ignored.

If the platform is having several components running with downrev FPGA then all of the components should be updated. See Section 4. below.

This document also contains the procedure to check the FPGA versions and how to update.

When replacing a CMIOU on M7-8 or M7-16 servers, the procedure described below must be applied to check and update the FPGA version running on the newly installed CMIOU.

Updating the FPGA requires to power cycle the component. A complete platform power cycle is NOT required. This can be done by re-seating the CMIOU.

This document provides the methods to perform this operation.
